摘要：
The studies aimed to evaluate longwall productivity in the Talda-Zapadnaya 1 Mine are carried out with regard to the technological parameters of the drum shearer and capacity of the armored face conveyor in mining thick methane-bearing coal seam. It is found that methane release reduces with increasing output of the shearer, and allowable longwall length and capacity by the gas criterion are determined. The length of longwall 6605 is optimized by the maximum annual profit of the mine.
