多断层矿区回采方案数值模拟分析研究

Numerical simulation of mining schemes in mine with multi-faults

为了保证漂塘钨矿东部矿区回采的安全,根据矿区的开采现状以及采空区、断层的相互关系,提出两种回采方案,并利用有限元软件FLAC3D对两种方案进行数值模拟比较分析。分析结果表明,东区留556、616中段为隔离层,将有效保护采场上覆岩层,在不利的地形地质条件下有利于东部区域资源回采的整体安全。

In order to ensure the safety of mining in the east part of Piaotang Mine, two mining schemes are proposed according to current mine situation and the relationship between goafs and faults, then these mining schemes are modeled and comparatively analyzed by FLAC3D. Analysis results show that if 556m and 616m are kept as isolative layers, it will protect the rock stratum effecti,Jely and contribute to overall mining safety of the east part in bad geological situations.
