摘 要: | 在露天煤矿的开采中,前期经过小煤窑开采破坏所形成的采空区给露天煤矿的正常开采带来了很大的危害,采用何种有效的爆破方式使其上部的覆盖层由地表塌陷填实采空区,将对露天煤矿的后续开采安全影响极大。本文通过铁长沟露天煤矿采空区塌陷爆破实例进行分析和解释。

Abstract: | Mining in the open pit - mines, after all small coal mines that are formed early in the goaf mining damage to the normal exploitation of opencast mine is a big danger. Blasting the way it used to effectively cover from the upper overburden of mined areas. The opencast mine will be a greal impact on mining safety. By Tiechanggou open - pit coal mine collapse blasting on emptied stope examples for analysis and interpretation. |
