NEV MINING 1TBODS INCREASE OUTPUT
INNOVATIONS IN BOSNIAN MnI3S -- Barba, No 76, 3o mar 49
Production in Bosnia and Berosgcvina mines will be greatly increased
during 1949 through increased mechanization and new working mothods.
Cutting according to the broad-face system, which has been employed
heretofore only in the Zenica mine, will be adopted this year to several
other mines, inoludi}Ig the NrakanJ and Breza brown coal mines and the
Kroka lignite mine. Preparations are being made In one part of the Makanj
mine to introduce the new "B" system of cutting, which will greatly inore,e
labor efficiency.
The adoption of new cutting methods han already increased production
at the Nliceka mine by 10 - 20 percent.
i
Mhaking conveyers are bring installed at Sakam~ and drilling will be
mechanized. The acne at M1l,evina in Pooa Srez will be electr?fled, and
a dry separation pleat will be built there to imp:eve the quality of the
coal..
In the Tcsnios mine, large-scale prospecting has revealed rich
dronits of coal around Livno. They will be exploited systematically
this year.
NEW IIETROD 8Pi~l COAL WORKING -- Barba, No 76, 30 Mar 49
Mirko Perisic, an engineer at the Alekeinae coal mines, hoe diseov'ned
an improved method of cutting that will permit the working norms to be
raised by 17 percent.

angle in the middle of the face and 12 more holes around them in a predeter-
mined pattern. The explosive is set.-'off in such a way that the four holes
in the middle explode first, making a cavity in the face, and then the other
holes explode. Relieved of pressure from the middle of the face, this part
disintegrates much more readily.
This method was known previously in Yugoslavia, but was not used at the
Alekeinsc mines until 14 January 1949. The new method cuts twice the area
and requires only about half as much explosive as the former method. It Is
also being applied to work in stone ruerries and will be adopted in all
Serbian coal mines.
5T3 HIMM BEAT QUARTER PLAN -- Borba, No 77, 31 Mar 49
)%ny Slovenian mines have completed their production plane for the
firet.quarter of 1949 ahead of schedule. The Trbovlje coal mine, which
exceeded its February plan by 4 percent, completed its 3-month plan 3 days
ahead of, schedule. The 8enaso, Liboje, Pecovnik, and ifanizerica mines also
fulfilled their plans ahead of schedule. The Volenje and Z,aburouice coal
mines and the mine at Lasko are expected to most their plans on time.
The best results were achieved by the mine at Sent Janz, which completed
its plan 10 days ahead of schedule, as a result of the prompt completion of
preliminary work art a new coalfield. However, acme mines have not paid
sufficient attention to the preparation of now deposits while the old ones
were being exhausted. The Ehoevje mine, for example, failed to most its
January plan by about 20 percent and so was unable to meet its 3-month
plan. Its old seam had been exhausted in December.
The Zaeorje coal mine will fulfill its 3-mouth plan on time. Well-
organized youth brigades at the Urastnik and Lasko mines are achieving
excellent results.
