机械化回采巷道矿压显现规律与围岩控制技术研究

Study on the Law of Ground Pressure Behavior and Surrounding Rock Control Technology of Mechanized Mining Roadway

为解决煤矿生产中支护方案并不完全适用于工作面导致对围岩控制效果不佳的问题,以某矿2173回采巷道工作面为研究对象,在对其顶底板条件分析的基础上,对该工作面的矿压显现规律进行分析,并结合支护难点提出了有效的支护方案,通过对支护后顶板离层量的监测验证支护方案对围岩的控制效果。

In order to solve the problem that the support scheme is not completely applicable to the working face in coal mine production,which leads to poor control effect on surrounding rock,the 2173 stope roadway working face is taken as an example.Based on the analysis of its roof and floor conditions,the law of ground pressure appearance of the working face is analyzed,and an effective support scheme is proposed in combination with the support difficulties.The control effect of the support scheme on surrounding rock is verified by monitoring the roof separation amount after support.
