摘要
以常顺煤矿9105进风巷为研究对象,采用理论分析的方法对受强烈动压影响巷道围岩的破坏机理进行深入研究,结合工程经验确定了9105进风巷围岩变形控制技术对策,制定了高预应力强力全锚索支护方案与支护参数。9105进风巷支护试验结果表明:高预应力强力锚索支护技术对强烈动压巷道服务期间围岩变形控制效果显著,提高了常顺矿煤炭资源利用率,为矿井后续强烈动压巷道的使用提供技术依据。
It taking 9105 air intake roadway of Changshun coal mine as background, the broken mechanism of surrounding rock inroadway that influenced by strong dynamic pressure was analyzed deeply, surrounding rock deformation control measures of 9105 air intakeroadway was determined with engineering experience, and high prestress strengthen cables supporting scheme and its parameterswere formulated. The practical in 9105 air intake roadway showed that surrounding rock deformation control during service period ofstrong dynamic pressure roadway with high prestress cables supporting technique was obviously, coal resource utilization of Changshuncoal mine was improved, it references for similar situation.
