摘要
铜坑细脉带矿体的破碎带矿岩具有氧化自热自燃特性,因而在开采中发生了井下火灾,为此决定用灌泥浆扑灭坑内自燃火灾。本文介绍试验研究情况,结果表明这一方法是行之有效的。
The ore and walls in the narrow vein zone of Tongkeng ore bodies specialize in oxiding spontaneous combustion,so the underground spontaneous combustion happened during mining. In that case, the slurry mud was grouted to extinquish the mine spontaneous combustion. This paper introduces the extinquishment test, analysis and studies the grouting technique and its effect. The result showed that this grouting method is available for the mine.
