摘要
极薄煤层的开采由于其工作空间狭小,由此带来工人劳动强度大、工作条件恶劣、安全事故多、设备配套困难、投入产出比高、效率低、经济效益差等问题,综采工作面由于设备占用空间大,空间不足的问题更加严重。采用"限定变形"理论,确定合理的支护强度限制顶板下沉,通过在斌郎煤矿N1014极薄煤层"爬底式"综采工作面应用,取得成功。
Lacking of work space is the major difficulty probleme of the mining in thin coal seam. Some relative problems such as high labor intensity, abominable working conditions, more accidents, e- quipment incompatibility, the higher of input-output ratio, low efficiency and poor economic, more serious problem from insufficient space are appeared in fully mechanized face. The reasonable strenght of support- ing roof is determined based on the ＂ limited deformation＂ theory, and it is applied to thin coal seam N1014 ＂floor creeping＂ fully mechanized mining face successfully in Bin Lang coal mine.
