特殊条件下工作面设计与施工管理综合效益分析

Comprehensive benefit analysis of working face design and construction management under special conditions

黄岩汇煤矿15111工作面,寺家庄铁路压煤662.8m,开拓巷道掘进滞后。特殊条件下利用铁路压煤区设计措施巷(煤巷),开拓巷道、措施巷两条线平行作业,共设计五个贯通,提前完成采掘接续的综合效益分析。

The 15111 working face of Huangyan Hui coal mine and 662.8 meters of coal pressing coal in Sijiazhuang railway are lagging behind. Under the special conditions, we use the design measures of the railway coal pressure area（roadway）, and develop the parallel operation of the two lines of the roadway and the measure lane. We design a comprehensive benefit analysis of five connections and finish the excavation and connection ahead of schedule.
