BUT LAG IN PRODUCTION
DIRECTORS RESPONSIBLE FOR SLUMP -- Pravda, 11 Aug 50
In the first half of 1950, the Krivoy Rog Iron ore Basin owed many thou-
sand tons of ore by failing to meet its production plan, and this lag nat.u?-
..
rally has affected many metaliurgii:al plants of the South and Center. The
substantial inner reserves of the basin have not yet been utilized, The new
mining technology is not being used at full capacity. At the "Novaya!" Mine
of the Mine Administration imeni R. Lyuksemburg, loading machines often lay
idle due to delays in getting empty cars to the stopes. At a number of mines
the compressed-air mains are in poor ccnd.ition\and repairs do not conform to
schedule, with the result that the supply of compressed .sir to the drill ham
mer!: is irregular and the productivity of the drillers reduced. The workers'
attitude toward machine equipment is not good and is the direct result of a
general lack of responsibility for tools, an attitude which is rooted in the
Krivbass (Krivoy Rog Basin).
Directors of the "Krivbassruda" Trust limit their action against this
MMost outtresponsible ine-
evil by protests in conferences andewworker

de-
this administrative negligence is Nedin,
partment, and Pozul'skiy, senior engineer in the same department.
Mine development operations are in a serious slump. In the first half
of 1950, the Mine Administration imeni R. Lyuksemburg completed only 63 per-
cent of the plan for development work. Again, the trust and mine administra-
tion directors have taken nb responsibility for the shortcomings. Vegner,
chief of the Kapitallnogo

development plans.
The efforts of leading workers are not getting the attention they de-
serve. The number of shaft-sinking brigades operating 'at high speed has re-
cently decreased by almost one third. At the Mine Administration imeni
R. Lyuksemburg, the sinking brigades are high speed in name only, since each
brigade advances less than 2 running meters per day. No one at the basin or
in the mines is taking the leadership for promotion of high-speed campaigns
or other advanced methods of work.

The mechanization of such labor-consuming operations as the collection
of ore and wet drilling are going extremely slowly.
MINES ACHIEVE HIGH MECHANIZATION LEVEL -- Gornyy Zhurnal, No 7, Jul 50

With the wide use in the mines of pneumatic support columns; automatic
feeders, telescopic hammers, and drill carriages, drilling had been automat-
ized 91.21 percent as of 1 January 1950. At the following mines, drilling
is 100 percent automatized; "Novaya" Mine of the Mine Administration imeni
K. Libknekht, "Kapital'naya" Mine of the "Zheltaya Reka" Mine Administration,
Mine imeni Ordzhonikidze of the "Zheltaya Reka" Mine Administration, and
"Tsentral'naya" Mine of the Mine Administration imeni Frunze. In 1950, drill-
ing will be made 100 percent automatic in all mines of the basin. At present,
wet drilling is being adopted with good results and has been introduced in all
mines.
Substantial qualitative changes have been effected by the introduction
of more powerful scraper winches with 20 to 30-kilowatt motors, heavy-duty
electric locomotives with the weight on drivers of 10 tons, 5 to 6-ton mine
cars, excavators for loading railroad cars, and others.
In 1949 and the first half of 1950, the park of mine machines and mechan-
isms increased over the prewar period, and the equipment has improved in qual-
ity. The mines are now using the more powerful drill hammers designed for wet
drilling. Loading machines for mechanization of-the removal of rock and ore
in development workings are having wide circulation throughout the basin. The
mines are also equipped with modern transport facilities.
The following new types of machines were tested in 1949 and introduced
into mining operations: NIGRI-4 drill machines, percussion-cable drill machines,
VCh-1 pneumatic loaders for collecting rock during sinking of shafts, mechanical
installations for unloading timber from railroad cars, pneumatic closing devices

for mechanization of loading from the manways, automatic ventilating doors,
automatic switches, PK-12, PPK-17, and PPK-21 pneumatic support columns,
drill carriages, ventilators, dust absorbers, mechanical chargers for verti-
cal deep-hole drilling, new and improved types of PR-35, PR-51, and PP-30
drilling machines, and others.
The Mine imeni Ordzhonikidze is testing a drill-assembling machi.n- for
use in advancing raises. The "Severnaya" Mine of the Mine Administration
imeni Kirov has complete all auxiliary structures for and has begun tests
of a large grab bucket for removing rock in advancing a vertical shaft. The
rock will be brought directly from the face to the surface by the bucket.
The work of drilling in advancing the shaft will be completely mechanized.
A ventilation shaft at the "Gleyevatka" No 1 Mine of the Mine Administration
imeni Frunze is being sunk by a shift-drilling machine.
Loading and unloading of materials in the shafts and on the surface,
haulage of materials and equipment in sublevel workings, and some auxiliary
processes such as delivery of supports to sublevels, shunting operations in
the shafts, removal of ore through the manways, and apportioning of ore into
railroad cars, are all not sufficiently mechanized. Timbering of various
workings and crushing of oversize pieces of ore in screening areas and on
accumulation (akkumuliruyushchiye) levels are completely unmechanized.
The lag in mechanizing such operations is explained by the length of
time involved in the design, production, and testing of new machines, and
in some cases by the insufficient utilization of existing machines which
have alredy been tested and recommended, such as the VCh-1 and PML-4 load-
ing machines, cable and pole installations for unloading timber, and others.
In 1950, it is planned to increase sharply the mechanization of opera-
tions which are either little mechanized or completely unmechanized. How-
ever, the wide utilization of basic machines and the achievement of a high
level of mechanization of individual operations (see Table 1) is still not
adequate to meat the demands on the basin for increased iron-ore output.
There should be a conversion to complete mechanization of the entire tech-
nological process of mining ore.
One step toward achievement of full mechanization of the basin's mines
was the conversion in 1949 of the "Komintern" Mine, Mine imeni Kirov, and
the "Novaya" Mine of the Mine Administration imeni K. Libknekht and the
"Kommunar" Mine of the Mine Administration imeni Dzerzhinskiy, to full mech-
anization. The basic production processes were mechanized according to a
standard plan drawn up by "Krivbassproyekt" (Krivoy Rog Basin Planning) for
the "Komintern" Mine.
It soon became clear that for successful adoption of complete mechani-
zation, technical plans for all four mines and working plans for production
of new-model mining machinery needed to be drawn up. The delay in the plan-
ning work, because of the newness and complexity of the problems involved,
and the lack of the necessary machine-design base, retarded the progress of
complex mechanization. The technical plan for the "Komintern" Mine was com-
pleted in May 1949, and somewhat later for the other three mines. Despite
the planning lag, work went ahead in the mines on mechanizing basic and auxi-
liary operations by extensive use of already tested machines. In 1949, the
mechanical equipment in these mines increased considerably over 1948, and
underground and surface haulage was 100 percent mechanized. Table 2 shows
the increase in the mechanization of basic operations in 1949, with the 1948
level taken at 100 percent:

The following difficulties were encountered in converting the four mine
to complex mechanization:
1. Lag in planning and designing new models of mining machines necessary
for full mechanization of the entire cycle of mining operations.
2. Insufficient rate of production and adoption of new models of ma- L
chines by "Kommunist" Plant.
3. Unsatisfactory supplies of machines and electric motors which had
already been adopted to production.
4. Insufficient utilization of existing equipment at certain mines.
The continual increase in basic production and the wide adoption of mech-
anization demand a radical reconstruction of the design, production, adoption
to production, and the utilization of new machines. In 1950, the categories _
of new models of machines planned for complex mechanization of the mines must
be increased sharply, and the production of these machines must be adopted
successfully. Series production of the new models tested in 1949 should be
organized and on a scale sufficient to meet the mines' requirements fully.
Together with this, the output of machines already widely used in the mines
should be considerably increased.

For the future development and completion of complex mechanization, the
design, experimental, and machine-building base of the Krivbass should be ex-
panded. The Ministry of the Metallurgical Industry must give its assistance
to this end.
The technical policy of mechanization of the entire technological cycle
in the Krivbass is directed mainly to the following:
1. Achievement of full mechanization of basic labor-consuming opera-
tions by already tested methods with the use of machines adopted to produc-
tion and in the process of production at plants.
3. Development of plans and new models of machines for extensive
mechanization of those sectors of the basic and auxiliary operations which
are not now mechanized or only slightly mechanized.
5. Maximum automatization of basic and auxiliary processes and dis-
patcher services.
For successful completion of the first two points, the "Kommunist" and
Automobile Repair Plants and the Central Machine Shops of the "Krivbassruda"
Trust must organize output of machines.:nd equipment in sufficient quantity
to meet all requirements of the mines.
To meet the third oint, the "Krivbass royekt," "Kommunist" Plant, TsKB
~entral Design Bureau of "Glavmashmet" Main Administration of Machine
Building for the Metallurgical Industry?7, aad the "Krivbassruda" Trust
should speed development of working drafts of new models of machines designed
for complex mechanization as well as the production and testing of experimen-
tal models and organization of their series production. Included among these
machines are: 1950 models of PR-24, PT-32, PR-32, P1-50, PK-42, PK-50, PK-60,
PP-62 drilling machines; incline drilling machines; mechanical charger for
deep-hole drilling; scraper winches; loading machine with conveyer; inclined
block hoist for hoisting workers, equipment, and materials on sublevels; cars
for transport of workers; car.-cleaning machines; device for automatic unload-
ing of tipple cars; mobile machine for hoisting and laying timbering material
in shafts and other workings; motor cart (elektrokar) for transporting mate-
rials and equipment throughout the workings; machine for unloading cement and
other loose materials from railroad cars; suspension-type drill carriage for
use in advancing and sinking shafts; automatic ventilation doors for haulage
ways; remote control mechanisms for scraper winches; switches, ventilators,
and other machines. At the same time, the Ministry of the Metallurgical In-
dustry should provide uninterrupted supply to the mines of special apparatus
and devices needed for automatization of production processes and dispatcher
services.
Together with the development of mechanization, improved methods of
working have been introduced in the basin. The use of deep-hole drilling,
in comparison with other systems used in the basin, is helping to decrease
the percent of cutting work and to increase considerably the productivity
of the driller and stoping workers, while at the same time providing safer
working conditions. The elimination of the screening levels, conversion to
the use of accumulation levels in mining by the block caving or the block
and sublevel caving systems combined, as well as by other systems, has
created favorable prospects for the use of heavy-duty scraper winches and
heavy-duty electric locomotives and cars, and has helped to increase produc-?
tivity of intramine transport.

The mechanization of the hoisting of men, materials, and equipment in
sublevel workings and the wide use of accumulation workings in blocks are
helping to provide a further increase in the height of the level, to simpl-
ify the method of stripping and development of levels and blocks, to de-
crease sharply the volume of labor-consuming development work, and to open
a new stage in mechanization with the use of larger and more powerful equip-
ment.
