Jastrzebska Spolka Weglowa SA announced recently that the PW -1 plough longwall in seam 358/1 has the initial strike of 720 meters and the length of 200 meters. The coal is mined in a seam with the thickness ranging from 1 to 1.4 meters. For the time being, the longwall is at the commissioning stage, but the target daily progress is planned to be in the range of 8.2 meters, with the daily output of 3 thousand tons of coal.

The longwall shearer comprising: the GH9-38/VE plough, JZR-11/25 mechanized roof support sections and PF4/932 face conveyor, supports operation of seams with the thickness from 1 to 1.7 meters. The plough head may have a cut of as much as 21 centimeters, working at the speed of 1.9 meters per second. Such fast daily progress of the longwall front requires efficient preparation of longwall roadways.
