群力煤矿矿井巷道布置优化

Roadway Layout Optimization in Qunli Colliery

通过对群力煤矿巷道现状的描述,分析存在的弊端,对原有巷道布置进行优化,集中布置三条井筒,通过区段集中布置石门揭穿各煤层。优化后巷道施工有效减少揭煤次数,矿井系统更加简单合理可行;井巷工程量大幅减少,安全生产方面更适合当前综合机械化开采需求。

Based on the present situation of roadway and its existing drawbacks in QunLi Colliery, the paper presents the optimization on the original roadway layout by centralized arrangement of three shafts and crossheadings in uncovering coal, which has effectively reduced the coal-uncovering times, and the engineering quantity with simple and reasonable mine system suitable for the current comprehensive mechanized mining demand in safety production.
