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。  

关键词: 极薄煤层, 综采, 顶板控制

Abstract: 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, equipment 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 supporting 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.   

Key words: Extremely thin coal seam, Fully mechanized mining, Limited deformation, Roof control
