摘要
斜沟煤矿地表上有岚漪河流过,为了保证煤矿开采的安全性,需要划定相应的保护煤柱。介绍了岚漪河保护煤柱留设方法,并选取了合适的参数来划定保护煤柱的范围,可以为煤矿的安全开采提供一定的参考。
There is Lanyi River on the surface of Xiegou Coal Mine.In order to ensure the safety of coal mining,it is necessary to delimit the corresponding protective coal pillar.This paper introduced the retaining method of protective coal pillars for Lanyi River,and selected appropriate parameters to delimit the scope of protective coal pillar,which can provide certain reference for the safe mining of the coal mine.
