Abstract: This article is devoted to the studies of geomechanical safety performed in longwall 50-03. The aim of the studies was to validate the possibility of mining seam 50 by longwalls 400m long by having identified the stability, load properties and cavability of the active roof strata in seam 50, the stability of the seam floor strata, establishing the required rate of advancing face 50-03 to ensure the required performance of the long-wall and geomechanical safety in the longwall. Based on the anticipated loads and load distribution on the powered supports, the required geometrical and power parameters of the powered supports were determined for mining seam 50 with the indicated face output. The results of the study of geomechanical processes in longwall 50-03 show that the geomechanical safety control in high-performing faces with intensive exposure of the roof should be done by maintaining the appropriate speed of longwall advancing, the rate of coal extraction in the longwall, the speed of longwall supporting.

Key words: high-performance mining seam 50 longwall 50-03 abutment pressure cavability the roof of the seam the extraction pillar the rate of face advancing
