SHIELD SUPPORT CONTROL METHOD Russian patent published in 1999 - IPC

FIELD: mining industry. SUBSTANCE: this can be used in development of thick steep coal seams. Shield support control method implies successive cutting of coal and separate setting of bases and shield support due to descending rock matter. Shield support has guide members with slide members and stops installed in support. Determined is position of slide member relative to stop which is nearest to seam floor. Cutting of coal is performed at seam roof with setting of shield support at L <1/2 h, or coal cutting is performed at seam floor with setting of base at L > 1/2 h, where L - measured distance from stop to slide member, m, h - full stroke of slide member, m. Application of aforesaid method allows for determining position of shield support relative to base and enhancing safety in carrying out mining operations under support. EFFECT: higher efficiency. 2 dwg
