本文列举了造成大倾角煤层底板破坏的主要因素和影响这类煤层底板破坏滑移发展过程的主要因素。着重分析了不同采煤方法的应力环境,结构体特征,“顶板—支架—底板”相互作用对底板破坏滑移的影响及作用机理。
This article lists the main factors that lead to the destruction of the coal seam floor and the main factors that affect the development of the destructive slip of the coal seam floor. The stress environment, structural characteristics and the influence mechanism of “roof-bracket-floor” interaction on the failure and slippage of the floor are emphatically analyzed.
