APPLICATION OF THE SHORTWALL FACE SYSTEM WHEN DEVELOPING COAL SEAMS PRONE TO DYNAMIC PHENOMENA

The article describes the features of the system short faces of room and pillar systems on their geomechanical and geometrical parameters, consider using the system short faces in seams prone to rock bursts and sudden outbursts of coal and gas. The variant flowsheet short faces when thick seam mining unsafe gas-dynamic, with the layer of coal extraction from the camera is tilted congresses and application safe pillars. Also, the basic elements of the short faces. The main parameter in the configuration is being handled, blocks passage of the main roof caving. Calculated expressions to determine the ultimate collapse of the main span of the roof. In conclusion, briefly describes the use of the short faces when developing thick seam unsafe gas-dynamic in the mine «Raspadskaya- Koksovaya» in research trials.

Key words: TECHNOLOGICAL PLANE, SYSTEM DEVELOPMENT OF SHORT WORKING FACES, COAL SEAMLIABLE TO ROCK-BUMPS, LIMITING THE SPAN OF ROOF COLLAPSE
