METHOD FOR MINING ANTICLINE THICK COAL SEAM

摘要

Usage: The invention may be used in the mining industry in developing anticlines thick coal seams. SUMMARY OF THE INVENTION: thickness of the coal under the flexible Kim overlap in the joint part before undercut recess cuttings vertical slits, which is carried out between the recessed drifts traversed by at roof and the soil layer in the boundary zones of the hinge portion with flaps and a recess on carbon are simultaneously upper and lower drifts, starting from coal-cutting slots ahead of the upper drifts. 3 yl.
