榆树沟煤矿开拓方案研究

Study on Mining Plan of Yushugou Mine

榆树沟煤矿主要开采3号煤层、14号煤层及14-1煤层,表土层较厚,且含有两个含水层,从施工条件上看,宜采用立井开拓方式,然而技术上也存在斜井开拓的条件,通过经济技术比较对设计的两种开拓方案进行比较,最终确定矿井采用主斜井-副立井的综合开拓方式。

Yushugou Mine mainly explored No. 3, 14, 14- 1 coal seam, the surface was thick, with two aquifer, vertical shaft mining was proposed considering construction condition, but the inclined shaft was allowed technically, the two mining plan was compared from economic and technical terms, the comprehensive mining technology of main inclined shaft- auxiliary vertical shaft was put forward finally.
