摘要
二道沟金矿目前采深超过700m,按我国采矿手册有关规定已进入深井开采,出现了一些不正常的地压现象。分析其各种地压现象的致因,并揭示采用浅眼留矿法开采极薄矿脉形成的大量采空区对矿山生产的危害,提出相应而且可以施行的解决对策。
Erdaogou Gold Mine pick deepth about 700m, according to Mining Handbook it belong to deep mining. This article, study on genesis of effect on crustal stress in deep mining, open out the disserve of empty section formed by adopting short -hole shrinkage stoping method in thin vein mining. The counte measures are adopted.
