对特大型矿井主井开拓方式选择的探讨

Discussion on Selection of Development Method of Main Shaft of Large Mine

以察哈素矿井开拓方式为例,提出主斜井方案、主立井(1个主井)方案、主立井(2个主井)方案,通过技术经济比较分析,发现具有类似于察哈素矿井建设条件的新建特大型矿井主井,采用斜井开拓方式相对于立井开拓方式优势明显,应该优先采用斜井。

Taking the development method of the main shaft of Chahasu mine as an example, presents main inclined shaft, main shaft(1 shaft) and main shaft(2 shafts), through comparative analysis of the technical and economic, the main shaft of new large mine was foud to have similar Chahasu mine construction conditions, the development method of inclined shaft compared with the development method of vertcal shaft has obvious advantages, should be given priority inclined shaft.
