深部矿井采煤及充填空间优化布局方法研究

Optimization Layout Method of Coal Mining and Filling Space in Deep Mine

以屯城煤矿为例,介绍了1种深部矿井采煤及充填空间优化布局方法。该方法采用了井下新增的跳汰分选系统,并将其布置到井下转运硐室,同时在1303N-1与1304N两个作业面进行布置。通过应用得知,现场作业面围岩强度较高,表明留巷围岩符合规定要求,可以提高井下作业的安全性,确认了深部矿井采煤及充填空间优化布局方法具有较高的应用价值。

Taking Tuncheng Coal Mine as an example,an optimization layout method of coal mining and filling space in deep mine was introduced.In this method,a new jigging sorting system was installed in the underground transfer chamber,and simultaneously arranged in 1303N-1 and 1304N working faces.Through application,it is known that the surrounding rock strength of the site working face is high,indicating that the surrounding rock of the roadway is in line with the specified requirements,which can improve the safety of underground operation,and confirm that the optimization layout method of coal mining and filling space in deep mine has high application value.
