摘要
本文通过对巷道支架载荷和围岩变形观测数据的统计分析,探讨了漳平煤矿地应力的变化规律。通过分析讨论了矿井支护改革方案,为漳平煤矿控制地应力找出了有效的途径。
In this paper, through analysing loads on the supports and deformations in the surrounding rocks of the road ways by statistical observation, authors study the changing laws of stresses in ZhangPing coal mine. The effective ways are discussed for controlling the strata stresses in coal mines by analysing the actual examples.
