察哈素煤矿31315工作面停采期间巷道变形原因分析

Research on Causes of Roadway Deformation during Stopping of Mining in 31315 Working Face of Chahasu Coal Mine

针对察哈素煤矿31315工作面回采过程中因长时间停采导致31315运输巷围岩变形增大的问题,通过顶板围岩裂隙发育特征实测研究了31315运输巷在停采期间的变形破坏原因,并提出了相应的解决措施。为同类条件下工作面开采时回采巷道围岩控制技术方案选择提供了依据。

Aiming at the problem of the increase in deformation of the surrounding rock of the 31315transportation lane due to long-term stoppage during the mining process of the 31315 working face of Chahasu coal mine, the cause of deformation and failure of the 31315 transportation lane during the stop of mining was studied through the actual measurement of the development characteristics of the roof surrounding rock fissures, and proposed corresponding solutions. It provides a basis for the selection of the control technology scheme for the surrounding rock of the mining roadway in the mining of the working face under the same conditions.
