摘要
为使厚煤层放顶煤开采中工作面巷道支护结构安全,基于山西同忻矿8102工作面巷道矿压进行监测,对巷道表面收敛、围岩位移情况、顶板离层、主动支护结构动载拉力等进行监测分析,预判其发展形态,保障生产安全。
In order to make the roadway supporting structure safe in the working face of top coal caving mining in thick coal seam, based on the monitoring of mine pressure in the 8102 working face of Tongxin Mine in Shanxi Province, the surface convergence of roadway, displacement of surrounding rock, roof separation, dynamic load tension of active supporting structure and so on are monitored and analyzed, and its development form is predicted to ensure production safety.
