摘要
可靠支护条件下采煤是煤矿井下开采的传统采煤方式,但作为典型代表的壁式采煤法有时对一些特殊赋存条件的煤层开采仍然难以适应,尤其是一些急倾斜不稳定煤层。本文试图通过对几种急倾斜煤层采煤方法的简略介绍和分析,来说明煤矿井下实现无支护采煤的可能性是存在的。
this article intends to give some brief introduction and analysis to the mining methods in a few kinds of sharp inclined coal seams,so it is explained that there is a possibility in non support coal mining in coal mine underground.
