矿井直流电透视法探测工作面底板岩层含水性

Observations the Rock Aquosity of Floor Undulation for Mining DC Electrical Penetration

为解决保安煤矿3701工作面开采受水威胁问题,提出了"工作面直流电透视法"的探测方法。监测结果表明:3701工作面底板岩层的含水性较弱,只是在局部地段出现电阻率略低于正常值的区域,这样区域的岩层具有弱的含水性,水量相对较小,可以安全开采。

To solve the problem of mining threatened by water of 3701 working face in Baoan mine ,this paper put forward the mothod of“mining dc electrical penetration”.Monitoring results show that the rock aquosity weak of 3701 floor undulation,only at local section,the resistance rate slightly lower normal and the rock have a weak aquosity. Because of relatively small amount of water in those place,coal mining can be safely.
