调整采煤机滑靴高度对俯采工作面采煤机性能影响的分析

The Analysis on the Influence of Underhand Stopes Coal Mining Machine of Adjusting the Height of Coal Mining Machine Sliding Shoe

通过分析石槽村煤矿1102203俯采工作面采煤机受力状态,提出了该工作面俯斜开采的临界角度,分析了俯斜变化与采煤机对煤壁力、摩擦力之间的关系,采取了调整开采高度,预先留底煤改善俯斜角度和加高采煤机滑靴高度的方案,实现了俯斜开采工作面安全生产,取得了良好效益。

By analyzing the coal clutter’s stress condition of acting surface of Shicao Village Coal Mine, it has put forward its working surface’s critical angle of inclined mining and has analyzed the relation among underhand mining changes and coal wall force and friction force, adopted the scheme of adjusting the mining height, improving the underhand mining angle by leaving leftover coal in advance and heightening the Coal mining machine sliding shoe. It implements the secure production of underhand mining acting surface and earns good economic benefits.
