摘要
Abstract
Special strata of about 150~300mm between16, 17 coal seam and the mudstone lfoor of north shaft of dongda coal mine in North Teng coalfield, Platts hardness is between 3.8~8.7, and the joint is not development, lithology is ductile. in order to solve the coal mining machine cutting special rock problem, power, drum, arm and other key technologies of the shearer is studied.关键词
