FOREWORD
The objective of this report is to analyze the 2.5 billion ruble
figure which the Soviets reported to be the gross output of the USSR
coal mining machinery industry in 1955. Tb breakdown this figure,
published quantitative production figures of coal mining machinery
have been valued in ruble terms. For the majority of the items for
which the Soviets give no iploalcal figures, estimates hare been made
of the volume of production, and their ruble values calculated. The
1 July 1955 wholesale prices of coal mining machinery in the Soviet
handbook Materials and Equipment Used in the Coal Industrz were used
in estimating the value of the various types of coal mining machinery.
The paucity of production data and the difficulty of determining
an average price for each type of coal mining machinery make these
estimates subject to a considerable margin of error. Further refine-
ment of these estimates should await the appearance of statistics on
the quantity of production for a greater range of items of coal mining
machinery than the Soviets have so far published.
This study is part of a. larger ORR effort to determine the value
of output of the entire machine building sector in the USSR, which in
turn, contributes to ORR's study of Soviet economic growth--past?
present, and future.

The USSR reported that the value of the gross output of the
coal mining machinery industry in 1955 was 2.5 billion rubles. To
analyse this figure, the value of 1955 production of those items
of coal mining machinery for which the Soviets reported quantitative
production figures--coal combines,coal cutters, rock loaders and
electric mine locomotives-- was estimated. This estimate revealed
that these major items of coal mining machinery constituted only
8.5 percent of the reported gross output of the coal mining
machinery industrye quantitative estimates were made for other
important items on the basis of data on inventories model dit,
tribution and partial production. The estimated value of these
items approximated 60.3 percent of the gross output.
B6 data were available which permitted even crude estimates
of quantitative production of winches and hoists, mine supports,
ventilators, drills, and accessories. The value of these items
and any addition to unfinished production was assumed to represent
the remaining 31.2 percent of the gross output.
The total estimated valre of the gross output of the coal
mining machinery industry is shown in Table 1 below.

I.Introduction
Amid-1955 Soviet source reported the overall value of the gross
output* of the Soviet coal mining machinery industry to be over 2.5
billion rubles annually. 2/** At that time the industry consisted
of 35 specialised coal mining machinery plants producing about 600
types of coal mining eqpipment. This group of 35 plants constituted
a highly integrated coal mining machinery industry administratively
subordinate to the Ministry of the Coal Industry USSR and produced .
equipsent used in mine construction and development, as well as all
types of coal extraction and coal cleaning machinery. Later to 1955,
a new Ministry of the Construction of Coal Industry Enterprises USSR
crime into existence and assumed jurisdiction over 11 of the above-
mentioned 35 plants. The significance of this development, insofar
as this report is concerned, is that a separate breakdown of 4600385,000
rubles representing the value of the grows output for 1955 vas reported
for this group of plants. 3/ This value figure, although pinpointing'
a considerable segment of the 2.5 billion figure, is only of limited
usefulness, because the product mix of these plants, while oriented
toward shaft Sinking and mine construction equipment, also included
items produced elsewhere in the industry (mine cars, supports, pumps,
winches). This factor precludes association of the 460 million ruble
figure with mine construction equipment exclusively.
In the ensuing sections of this report, the 2.5 billion gross
production figure is analyzed to determine its composition. Section II
covers those items of equipment for which the Soviets issued quanti-
tative production figures for 1955. Estimates have been made of the
volume or production of each model known to have been in production
during 1955 and an average value calculated for each model based on
Soviet wholesale prices issued on 1 Jay 1955. Section III covers
those items for which data on inventories or on production at specific
plants permits approximations to be made of total national production.
These estimates are then valued as in Section II. A number of items
far which no data are available on which to base an estimate of
production are included in Section IV. These items are assumed to
comprise the residual portion of the 2.5 billion ruble figure.
* The term "gross output" refers to the total volume of output (goods
and services) in value terma produced in a given period. It includes
all cOmmercial production, alluTdMolsbed production, plants' own unused
semi-manufactures, and all the tools, devices, materials, and spare parts
manufactured by the plants of the industry in a given production period.
Gross output is calculated in wholermle prices, actual or comparable.
Repair services for other than the plants' own equipment are not included
in the gross output of the coal mining machinery industry. The coal
industry operates its own extensive repair facilities Apart from coal
mining machinery manufacture. The value of the gross output of these
machinery repair plants is always reported separately.

No separate estimate has been made for the value of production of
spare parts for coal mining machinery. Coal mining machinery plants
generally produce only initial spares which are sold with a new machine.
Coal face machinery, for example, is equipped with three of more sets of
major spares when it leaves the plant. These spares are wesumEibly
included in the price of the machine. Spare parts for repairs are
produced by the repair plants and shops of the coal mining trusts formerly
subordinate to the Ministry of the Coal Industry (27 plants and 86 shops)
and by the repair plants and shops of the former Ministry of Construction
of Coal Industry Enterprises (41 repair establishments).* Since these
enterprises are not part of the coal mining machinery industry, the spare
parts, and the new equipment, which they produce would not be included in
the. 2.5 billion ruble figure.**
II. Estimates of the Ruble Value of Coal Mining Machinery for Which
Production Data are Available
A. Coalface Machinery
Although coalface machinery is the most publicized of all the .
mining equipment, its ruble value constitutes a relatively small percentage
(slightly over 6 percent) of the total value of gross output. .Coalface
machinery includes coal combines, coal cutters, and coal and rock loaders.
It is the only category, with the exception of nine locomotives, for which
quantitative production data for 1955 are available.
1. Coal Combines
The output of coal combines in 1955 tatalled 731 units.
Below is the breakdown by model and estimated ruble value: ?
fnce the reorganization in 1957, these ministries no longer
exist, and the repair enterprises are subordinate to the Regional Economic
Councils, either directly or through coal or mine construction trusts.
** The gross output of these repair enterprises is sizeable, exceeding 1.4
billion rubles in 1956. More than half of this amount represented the value
of production of coal mining equipment. The value of the output of the repair
plants and shops of the coal mining trusts under the Ministry of the Coal
'Industry was 1,150,000,000 rubles of which 420,000,000, or nearly 37 pereent
was derived from repair services; 114,000,000 rubles, or about 12 percent
from spare parts production; and 585,000,000 or about 51 percent from the
manufacture of metal supports and miscellaneous equipment. V The value
of the output of the repair plants and shops of the Ministry of Construction
of Coal Industry Enterprises for 1956 was 267,100,000 rubles of which
96,156,000 rubles, or 36 percent was from repair and spare parts produc-
tion and 170,944,000, or 64 percent from the manufacture of metal supports
and miscellaneous. equipment. !!"/

Only two models of coal cutters were in regular production
in 1955 No breakdown of production by model is available, but the prices
on both models differ so slightly that they are both valued at the average
price of 34,500 rubles.

3. Rock Loaders
Although an overall production figure of 1,965 units for
rock loaders* is reported, it is not absolutely certain that all of these
machines were produoed within the coal mining machinery industry. A
popular loader, the MPR-6 (similar to EM-3) for example, was produced
at the time by the Ministry of Defense Industry, while other loaders used
in coal mining were, and still are, produced by the ore mining equipment
plant at Xtivey Rog. Another difficulty is the lack of data on the
breakdown of loader models manufactured. A great variation exists in the
price of rock-loaders -- 15,300 rubles for the small P14L-5 model and
200,000 rubles for the highly specialized, powerful, PJ-1.
The only concrete information on the nuMber of specific
types of loaders in production was obtained from
report which estimated the 1955 production of the EPM-1 loader at the
Druihkovka Toretsk Plant to be approximately 513 units, or slightly
more than 26 percent of the total output of rock loaders. ?/ The
Druthkovka plant is known to specialize in the production of the above
model and probably accounts for most of its output, which, however, does
not preclude the possibility of small numbers of this type of loader
being produced elsewhere in the industry, particularly because of its
widespread use. Assuming that an additional 5 percent or 98 units of
the overall output of rock loaders Was devoted to the 'production of this
machine by other plants, and that the Druthkovka plant accounted for
about 26 percent of the total output of rock loaders, the output of EP4-1
loader for 1.955 is estimated to be about 611 units or slightly over 31
percent of the entire output of loaders in 1955.
25X1B
The PMU-1 loader, which is used in steep headings, was
developed and tested in mid-1955 and probably did not go into full series
production until sometime in 1955. Considering the short time in production,
and the fact that this machine is used in highly complex rather than general
mining operations, it is unlikely that the PMU-1 accounted for more than
5 percent of the total output, or 98 units.
The pneumatic PML-5 rock loader, used almost exclusively
in the seams where the use of electric power is reatricted because of the
fire hazard, is said to be produced in large numbers. The PPM (2, 3, and 4),
referred to as a highly efficient machine, is also widely used in Soviet
mines. just what proportion of the output each one constituted in 1955
cannot be determined. Consequently, the remaining output of loaders,

(with the exclusion of 20 percent of the entire loader output which is

B. Mina Locomotives
In 1955 electric mine locomotive production amounted to 1,816
units.** Recent Soviet sources indicate that only 18 Percent of the
Soviet mine locomotive inventory consists of 10-14 ton machines, the bulk
of the inventory consisting of 7-8 ton units and a certain proportion of
the 2-ton light duty locomotive. 7/ For lack of more definite information
it is assumed here that the 1955 output of the 10-14 ton locomotive was
about 15 percent of the total, or 272 units. The output of the 2-ton
lightweight locomotive is assumed to be 20 percent, or 363 units, and of
the 7-8 ton locomotive about 65 percent, or 1,181 units.
* Excluding the 393 assumed to be produced outside the industry
** In 1957 the inventory of mine locomotives consisted of 12,316 units
of which 5,618 were of the trolley type and 6,698 of the storage battery
type. The fact that the inventory of battery type locomotives was almost
20 percent higher than that of the trolley type, suggests a higher
production rate for the battery type.

Because of the fire hazard, trolley locomotives are confined to intake
airways. The biggest weights are usually hauled by the 7-14 ton battery
locomotives; the small 2-ton types are used for light duty and materials
hauling. In estimating the rale value of locomotives, weight, rather
than type, is used as a criterion.
III. Estimates of the Ruble Value of Machinery Items for Which Production
Data Have -13een Derived
A. ClagntETLI1
There has been a steady increase in the postwar inventory of
conveyers of several thousand units per year. In 1955 the inventory of
scraper conveyors increased over the 1954 inventory by 4,556 units. The
inventory of belt conveyors increased by 978. units. The retirement rate
of conveyors, is not known. The retirement rate for fixed capital of the
coal industry is about 11 percent, ?./ This rate applied to certain types
of mining equipment would undoubtedly be too high, but applied to conveyors,
which are known to have a relatively short life, appears reasonable and
may even be low.
The 1955 inventory of scraper conveyors was 28,705 units. Assuming
that 11 percent or 3,158 units were retired, and adding to it the increment
to the inventory of 4,556 units gives a rough production estimate of scraper
conveyors of 71714 units. Correspondingly, the inventory of belt conveyors
in 1955 was 9,457 units. If 1,040 units were retired, the production of
belt conveyors is estimated at 2,018 units.
* The average price was derived 'by averaging all the prices for a given
weight locomotive.

B. Mine Caro
If Soviet plant production data are to be taken at face value,
the output of mine cars in the USSR in 1955 could have been as high as
175,000 to 200,000 unite per year./ The Xiselevakitining Machinery
Plant alone was slated to bring up its production of mine cars in the
1951-1955 period first to 70,000 and ultimately to 1000000 units per
year. 10 The Uzloveafa Mining Machinery Plant was reported to have
produc 180000 large cars (2 te 2.5 tons) in 1955. aai The Drushkovka
Toretak Plant, also known as a large producer of mine cars is esti-
mated to have produced 50,000 cars as early as 1951gi m;d. probably
increased its production of cora over that amount in 55. Mine
cars are also produced in considerable quantities at the InUisi
"Oornylk" and the Xrainyy Lucia plants and in varying quantities in a
number of other mining machinery plants within and outside the USSR
?veregi-price obtained from averaging the prices of all scraper
conveyor models in production in 1955. Price variations based on con-

meter 3.28 ft.) in length.

coal mining machinery industry.* An analysis of the inventory of mine
ears tends to coati= the 200,000 production estimate. The inventory
of mine care increased from r60900 units at the end of 1950 to 626000
units by the end of 1955. Li Soviet estimates put the service life of
a small car at about 4 years. AI/ Assuming a 25 percent retirement
rate and an addition to inventory of about 65,000 cars aarmally, the
production of mine cars for 1955 is estimated to be around 200,000 units.
Using the production estimate of 175,000 cars assumed to have
been produced by the coal mining machinery plants, the value of the
output of cars adds up to a considerable portion of the value of the
overall gross output of the industry., The average price of a 2 ten
and over car is estimated at 4,081 rubles.** If 15 percent of the
output (mumel on the inventory ratio) were devoted to the production
of the larger car it can be valued at about 107,126,000 rubles. Com-
puting the rens/fling output ef 148,750 cars at an average price of
1,076 rubles gives, a. figure or 160,055,000 rubles, making a. grand
total for all mine cars of 2670181,000 rubles.
* Met of the Soviet ears are small, only one to 1.5 tons. Only
15 percent of the inventory consists of cars 2 to 2.5 tons OT larger.
The average for the Donets Basin is 1.0e tons; for /Melo 1.37 tons;
Neraganda0 1.41 tons; Pechora, 1.57 tons; and for the I'nets Basin,

** The average was derived by averaging the price of all models
weigaing over two tons. Although the average price" used in this
report for each type of car seems realistic, the estimated overall
value of the output of mine cars appears inflated when compared
with the available production and value of output data of plants.
Per example the estimated value of the output of mine cars of the
eledbenik plant (specialized produeer of mine cars) exceeds by far
the given total value of the gross output of this plant for the year.
The total value of this output for 1955 is reported to be only 310019,000
rubles. go, Assuming that the plant reached only the 70,000 unit
production rate instead of the planned 100.000, and valuing the car
output at the lowest price listed? which Ia 705 rubles the total
value or the mine car output (49,3500000) would still ;mooed he
plants overall value of output by 18,331,000 rUbles. Computing the
output at an average price of 1,076 rubles would give a figure of
75,320,000 rubles, almost two and &half times the reported value
for 1955. la case of the ealoineek punt, the total value of output
for the year is given at 87,0020000 rubles. Al/ If the plant pro-
duced 18,000 large cars, as claimed their value at the average price
of 40081 rubles would total :3eeeeeee rubles leaving only 3165440000
rubles to seecunt for the value of other important items that the plant
is known to produce. These discrepancies cannot be reconciled at the
present time without additional information and further study.

D. Coal Clesilps_aq_Ema
Coal cleaning equipment includes a miltitude of Items ranging
from a TO ruble cable castor to a 193,000 rale drier. If only one of
each of the items included in the range of coal cleaning eqpipment had
been produced, the total value would amount to over 5,000,000 rubles.
As in the case of the major emaLfaa* machinery, the major items in the
coal cleaning product mix, on the basis of Inventory figures, do not
appear to constitute a very significant part of the probable total
value of coal cleaning equipment.* In 1955, two coal mining machinery
plants, frequently referred to in Soviet literature as those among
the largest and most important in the industry, were producing coal
cleaning equipment almost exclusively, supplying about 100 coal clean-
ing plants of the coal industry. Eli Unfortunately, no reliable labor
or sage data are available for these plants to be used in constructing
an estimate of the overall value of output. Generally, the coverage
given these plants makes them appear much larger than any of the plants
in the construction machinery category of which two plants have a
value of gross output reported at nore than 99,000,000 rubles each.
This factory together with the fact that the two coal cleaning equip-
ment plants are supplying such a large number of conaumer plants, mikes
it seem reasonable to place the value of their joint output in 1955
between 2500600,000 to 40000000000 rubles.**
* Mb production information on coal cleaning equipment is available,
other than the fact that almost all of it is postwar. In 1956, the
inventory of major coal cleaning machinery consisted 01'2,0000 screens,
650 crushers, 130 jigging machines, 100 pneumatic separators, 60
flotation machines, 200 centrifuges and 50 driers. 2.2/ Per the purpose
of extreme simplification and assuming no retirement taking place
(with the possible exception of screens), the above data averaged
over a 10 year period of 1946-56 indicate the production of 200 screens,
60 crushers, 13 jigging machines, 10 separators, etc., stnnually. The
total value of this assumed output would add up to only about 110000,000
rubles on the basis of the average price obtained by averaging the
prices of products in question. Doubling or tripling the figure on the
assumption that the 1955 production was greater than in the preceding
years, would not appreciably change the overall estimate.
** Wise coal cleaning equipment such as special ventilators, pumps,
vacuum filters, filters, etc. and a considerable quantity of spare
parts are also prbduced in repair plants and shops and are not in-
cluded in this estimate.

X. Nine Constructloniemchinery and Miscellaneous Equipment
Mb individual estimates can be made of the different types of
equipment produced by the eleven plants under the farmer Ministry of
the Construction of Coal Industry Nnterprises. Mbst of this equipment
consisted of construction imachinery including cranes bucket hoists,
excavators, ditch digging machines,. special construction equipaent
used in the installation of concrete blocks, electric cableways, etc.,
fitting*, and other metal structures. These plants also manufactured
items that were produced by other coal mining machinery plants pumas,
winches, mine ears tunnelling combines, and mine supports. The total
value of this output is given at 460,385,000 rubles. Assuming that
appromchmately 60,000,000 of this total is contained in the figure al-
located in this report for mine ow production,* the value of the
remaining output domes to about 400,000,000 rubles, or 16 percent of
the overall value of 2.5 billion rubles.
West of the mining machinery plants are rewired to produce a
ltaWAsuaber or consumer geode and selected items for other industries,
such as woode.workingtools? tractor spare parts, etc. The value of
such production is arbitrarily set in this report at 5 percent of the
total or 125,000000 rubles.

A. Mine Hoists and Winches
The largest and heaviest mine hoists) are produced outside the
coal mining; machinery industry, chiefly at the Bevo-Kramatorak and the
Urni. Wahine Building plants. Smallex hoists, with the drum diameter
of 2-3 meters are produced at the Stalino 15th Anniversey of the IMO
Plant. This ;lent is kuown to produce mine hoists for export to the
Ihropean Satellites and Communist Chime and probably was the rter
Of IO coal mine hoists in 2955 valued at 2,382,000 rubles. 2 No
data are, available on the production or inventory of these nachines.
light types of hoists appear to have been in production in 1955,
ranging from 87,600 to 202,400 rubles in price which indicates that
they may be a significant element in the pricing of the overall output.
* Artmitraray based on the possible Share of the total value of the
output of the Niselevsk plant (total value 31,019,000 rubles) and the
Uslovaya pleat (870002,000 rubles) devoted to nine car production in
1955. As was previously pointed out, the low figures of the total gross
value of output of both plants do not seem to correspond to the published
production data on mine cars for these plants and to the value assigned
to mine car production in this report.

Data on the output of winches are so scattered and incomplete
that it would be futile to guess at their value. The price of winches
ranges from 3,550 to 108,000 rubles, with one prototype costing as
much as 250,000 rubles. /a 1955, many of the winches were produced by
the group of plants producing mine construction machinery. Part of
their value is included in the value of the construction and miscell-
aneous equipment category.
EL Other
In addition to mine hoists and winches, there are many other
products of the coal mining machinery industry for which the value of
production cannot be estimated. No production data exist for pumps,
drills, ventilators, lamps, and smaller tools and accessories, aome of
which individually are of low value, but collectively form a significant
part of the total value. Quantative production data on large satin
sinking units, hydraulic mining evipment? mechanized mine supports
and props* and a variety of other equipment are also lacking. Part
Of the value of this output (pumps, supports, etc.) is contained in
the value of the construction machinery and miscellaneous equipment
category. The total value of the mine hoists and miscellaneous
items .Ls assumed to equal the unaccounted for portion of the 2.5
billion rubles 78140.19,00 rubles a figure which seems reasonable
for the aggregate value or such a 144, variety of items.**

The general orgenization of this 'oreakdown parallels that of the
subseqeent textual presentation. The first esteem!, which tncludes
coal combines, coal cutters, rock loaders, and electric mine locomotives,
is estimated from published production data. Sufficieet information
on eoal combines peraitted production estimates to be made by model in
Beetle* II of this report. Less information was available on rock
loaders and electric mine locomotives, so that estimates were devel-
oped fm deductions concerning the possible model distribution
within these categories. The total value of the equi,pment estimated
on the basis of production data is 211,800,000 rubles, or about 8.5
percent of the 2.5 billion rubles.
Me second category covers items for which only partial production
date were available and for which quantitative production estimatesend/or
andfor value of production were derived. This group includes such
important machinery items as conveyors, mine cars, and tunnelling and
heeding machines. Estimates of the value of conveyors and tunnelling
machines were based on inventory and model data. A crude estimate of
the value of mine car output was made from conflicting production
data and the reported value of the output of producing plants. The
value of the coal cleaning equipment was approximated from scattered
inventory data and the probable value of output of producing plants.
Construction machinery and equipment was estimated with fair certainty
by aggregating the data on the value of the output of the individual
plants engaged in the production of such equipment and making allowances
for other items produced by them. Consumers goods comprise the re-
minder of this category. The total value of the items in the second
category is estimated to be 1,507,181,000 rubles or 60.3 percent of
the gross output of the coal mining machinery industry.
The last category includes a variety of items such as mine hoists,
winches pumps drills, ventilators, lamps etc. as well as unfinished
production, whose value defies estimation ;ecause of the complete lack
of production data. The total value of these items is assumed to con-
stitute the still unaccounted for portion of the 2.5 billion rubles,
or 781,019,000 rubles, which is 31.2 percent of the total gross output.
