强径流区薄含水层注浆治理技术研究

Research on Grouting Treatment Technology for Thin Aquifer in Strong Runoff Area

强径流区薄含水层是煤矿采掘的潜在危险,高富水、流量大、流速快,给注浆带来了很大的困难。以孙庄矿12661工作面为例,对强径流区薄含水层注浆治理技术进行研究,为了工作面的安全开采,注浆过程中可以采取加固料、间歇注浆等措施。

Thin aquifers in strong runoff areas were potential dangers of coal mining,with high water richness,large flow rates,and fast flow rates,which brought great difficulties to grouting.Sunzhuang Mine 12661 working face was taken as an example,the research on grouting treatment technology for thin aquifers in strong runoff areas was carried out.For the safe mining of the working face,reinforcement and intermittent grouting should be taken during grouting.
