摘要
综采工作面在回采过程中经常出现刮板输送机、采煤机下滑,液压支架倾倒等现象,不仅影响工作面回采进度,而且很容易发生煤矿安全生产事故,给煤矿企业造成重大经济损失。西山煤电集团屯兰矿综采二队在28120综采工作面采用伪斜推进后退式综合机械化采煤法,保证工作面安全顺利回采,遏制了机械设备打滑现象,取得了显著成效。
The decline of semper conveyer and shearer and hydraulic support dumpling not only influence the stoping speed butalso cause safety accident with serious economic loss. The paper introduces the false-inclined-advance retreating mining methodwith comprehensive mechanization at 28120 fully-mechanized working face in Tunlan Colliery, which can guarantee the safe andsmooth stoping and restrain the sliding of mechanical equipment.
