DEVELOP NEW PROCESSES FOR SHALE EXTRACTION;
ESTONIAN SHALE MINES USE IMPROVED METHODS, MACHINERY
MOTOR FUEL, OTHER PRODUCTS EXTRACTED FROM SHALE -- Tallin, Sovetskaya
Estoniya, 20 Dec 51
Associates of the Ali-Union Scientific Institute for the Processing
of Shales; in collaboration with engineers of the Estonian Shale Gas
Plant in Kokhtla-Yarve, have developed new technological processes
resulting in the extraction of some types of motor fuel, raw material for
tanning leather from shale, in addition to household gas.
Great importance is attached also to the new method of obtaining so-
called frothing agents, used widely in the mining industry for concentrating
ores. Th.. new materials are 22-3 times as cheap as the previous ones.
Scholars of the institute have developed and introduced the technology of
gasifying shale dust, leading to the utilization of shale fines which previ-
ously had almost been discarded as waste.
KYAVA-2 MINE ACHIEVES HIGH PERFORMANCE -- Tallin, Sovetskaya Estoniya,
8 Jan 52
In 1951, miners of the Kyava-2 shale mine achieved considerable success,
keeping their promise to Stalin to deliver tens of thousands of tons of shale
above plan. In 1951, all technical and economical indexes improved over 1950.
Labor productivity of the cutting and loading personnel rose 17 percent.
The effectiveness of the work of the cutting machine increased 30 percent and
of electric locomotives 15 percent. Starting on 1 September 1951, operations
at Sections No 1 and No L were converted to the cycle work schedule.

Before every shift, electric inns and mechanics prepared the machines
for uninterrupted work. During the development shift such processes as
undercutting of the seam, transferring of the conveyer, and installation
of mine props were carried out so efficiently that the actual mining of shale
at the faces could proceed promptly. The entire cycle of operations in
shale extraction was completed in . 24-hour period.
Workers in Section No 4 had never fulfilled the production plan from
February to August, but, in September, after introduction of the cycle shed-
ule, the plan was fulfilled 102 percent. In October, plan fulfillment rose
to 112.6 percent, and in November to 123.2 percent. Since the introduction
of the cycle work schedule, the quality of the shale mined has improved with
a reduction of the rock content of almost one percent. Labor productivity
has had an average increase of 6 percent. Every worker in the section ful-
filled his norm in December.
In October, Section No 4 received the Transferable Red Banner of the
Ministry of the Coal Industry and the TsSPS for its distinguished performance.
Workers of Section No 1 also had great success.
In 1952, all sections of the'Kyava-2 shale mine will be converted to the
cycle work schedule.
IMPROVED MACHINERY RAISES PERFORMANCE OF ESTONIAN MINES -- Tallin, Sovetskaya
Estoniya, 4 Jan 52
In 1948, the first STR-30 conveyer was tested by engineers and miners in
the Kyava-2 shale mine, and it was proved that this conveyer cc?ild be used in
sh,_le as well as in coal mines. At present, the STR-30 is being reconstructed
in order to improve its technical and economic indexes considerably.
In Mine No 6 the chief of a section carried out experiments with a
cutting machine with a thin bar, manufactured by the Kopeysk Mining Machinery
Plant. This innovation makes it possible to decrease greatly the amount of
shale fines resulting from mining.
Operators of cutting machines in the Kukruse Mine collaborated with a
docent of the Leningrad Mining Institute in designing a new cutting chain for
cutting machines which is intended for cutting hard seams and which will save
a large amount of state funds.
Formerly, shale was cleaned by the manual removal of rock. Now, rock is
removed mechanically, thus saving for the state 8.8 million rubles per year.
SHALE MINE USES OPEN PIT-METHOD -- Moscow. Pravda, 22 Dec 51
The Vivikond shale mine in the Estonian SSR is being worked by the open-
pit method and has recently acquired two walking excavators. Recently, the
first of these excavators reached the main pit of the mine and was made ready
for action. The walking excavator will remove rock located on the surface of
the ground from the shale seam. The shale miners will then work the uncovered
shale seam with ordinary excavators. Employment of the new machines will
greatly accelerate shale mining. The second walking excavator is now being
assembled at the Vivikond shale mine.
