非正规采法的放顶工艺

Caving Coal Technology of Irrugular Mining Way

随着矿井储量的减少,只能依靠残煤回采弥补原始储量的不足,因此非正规单扒采煤方法值得推广和使用。文章根据矿压规律分析了扒顶煤的可行性,具体论述了扒顶煤的方法,同时分析了扒顶煤存在的问题。

Along with the reducing of mine reserves, the original re,ryes insufficiency is remedyed by mining the residual coal, so the irrugular mining way with pushing coal alone is worth popularizing and using. In the article, the feasibility of pushing coal is analyzed on the basis of mine pressure law. The pushing coal way is particularly expounded. The existing problems in pushing coal are analyzed.
