大倾角综采工作面支护中的防倒防滑技术

乌兰煤矿5767综采工作面煤层赋存复杂,倾角较大,造成工作面设备下滑及支架歪斜、挤架和咬架,严重影响工作面的正常生产。针对该工作面实际情况,结合理论分析和现场经验,找出设备下滑、歪斜的原因,从调整回采工艺和增设防滑设备两方面入手,对工作面设备防滑和防倒技术进行了研究,取得了预期效果,保证了工作面生产的正常进行。

Antitoppling and Antiskid Technique for Support in Fully Mechanized Face with Large Dip Angle

The coal seam occurrence of 5767 fully mechanized face in Wunan Mine was complicated and with larger dip angle,which offten cause the sliding of face equipment and the tilt and pressing of face supports,this serously affacted the normal production of the working face.To counter the actual condition of the face and in combination of the theoretical analysis with site test,the cause of sliding and tilt of face equipment was found out.Research was also made on the antitoppling and antiskid technology for face ...
