千树塔煤矿工业场地位置及开拓方式选择

Selection of Industrial Site Position and Development Methods in Qianshuta Mine

分析了千树塔煤矿的中北部及东北角两个工业场的地位置选择方案,结合其立井开拓方式、煤层赋存条件、开采技术条件、井下开拓布置和井筒检查孔资料等因素,设计了三个开拓方案,并进行技术和经济分析,最终选用中北部场地,"两斜一立"三条井筒开拓方案。

The paper studies selection of two industrial sites in Qianshuta mine： north central site and northeast one. Combined with their shaft development modes, coal seam occurrence conditions, mining technology, underground mine development, and shaft pilot hole data, three development plans are designed. On the technological and economical analysis, the north central site and the two-inclined-one-vertical-shaft development plan were chosen.
