天马山硫金矿段地压监测分析与控制

Monitoring analysis and control of ground pressure in Tianmashan sulphur-gold ore section

天马山矿业公司天马山硫金矿段经过十多年的开采,留下了大量采空区,采空区体积随着采矿生产而不断增大,目前采空区容积已达80万m3。为了保障矿山可持续安全生产,加强采空区的稳定性监测和对地压实施有效控制意义重大。介绍了天马山硫金矿段开采及采空区状况,对天马山硫金矿段采空区稳定性进行了分析,并提出了下一步采空区地压监测方案。

The total volume of goaf in Tianmashan sulphur-gold ore section has been increasing with the more than 10 years＇ mining production and achieved 0.8 million m3. In order to ensure the production safety, the stability monitoring and effective control of ground pressure in goal is of great importance. The paper introduces the mining method and goaf status in Tianmashan ore section. The stability of goaf is analyzed and monitoring plan of ground pressure is proposed.
