摘要
该文以张集煤矿1131(1)回采工作面沿空巷道侧压治理为例,张集煤矿通过对打锚杆钢带、锚索等不同技术手段对加强支护效果的分析,探索如何经济高效解决沿空巷道架棚支护条件下尖顶及折腰现象,以及控制巷道围岩变形的实用技术,通过现场检验,取得了良好的支护效果及经济效益。
That article takes control technology of the side pressure in drift on goaf for 1311 (1)mining face in ZhangJi Coal Mine as an example,By ana-lyzing different techniques means such as playing anchor rod、steel belt and anchorage cable ,to strengthen the supporting effect of Coal pillar ,exploring practical technology how to cost-effective solution Steeple and Hip breaking phenomenon of drift on goaf with supporting roof by shelf,and to control de-formation for roadway. through field testing,and achieved good supporting effects and economic benefits.
