摘要
采煤工作面矿山压力观测就是利用各种观测仪器或工具,对工作面及四周围岩的应力、顶底板变形与破坏、支柱压缩与载荷、煤壁片帮、支架变形与折损等宏观矿压显现量进行测量与记录,通过整理分析,掌握采煤工作面矿压显现规律,并以此指导生产。
The underground pressure observation in mine coal face measure and recorde stress around the rock face, deformation and is to use observation equipment or tools to damage in the roof and floor, pillars compression and load, coal wall - help, support deformation and impairment, and other macro - ground pressure , Through analyzing, it gathers mine coal face pressure regularity, and for guiding production.
