摘要
204综采工作面回采期间顶板出现破碎、冒落,导致工作面回采速度降低、移架困难、支架支护不到位,威胁着工作面回采安全。本文分析了顶板破碎、冒落原因,提出了"人工假顶+超前深浅孔注浆加固"联合治理措施。通过实际应用,控制了顶板冒落现象,取得了显著成效。
The roof of 204 fully mechanized face is broken and caving during mining,which results in the reduction of mining speed,the difficulty of moving frame and the inadequate support of support,which threatens the safety of mining.This paper analyzes the causes of roof breaking and caving,and puts forward the joint treatment measures of"artificial false roof+advanced deep and shallow hole grouting reinforcement".Through practical application,roof caving has been controlled and remarkable results have been achieved.
