摘要
针对任楼煤矿7240(上)南工作面回采过程中出现的机尾段歪架问题,从工作面矿压、工作面涌水影响和推进速度等角度,对歪架的原因进行了分析,并针对7240(上)南工作面的具体条件,提出了提高工作面支护质量、加强超前管理、减少甩采、合理排水等措施。
Aiming at the support inclining problem in southern of upper- 7240 working face in Renlou coal mine,the reason of support inclining was analyzed from the views of ground pressure, water inflow and mining velocity. And according to the specific conditions of upper- 7240 southern working face,prevention measures of supports inclining was proposed,including to improving working face support, enhancing pre- management, reducing turning mining, and using reasonable water drainage measures.
