铅锌矿采空区隐患治理与微震监测技术研究

Study on hidden danger control and microseismic monitoring technology of goaf in the lead-zinc mine

随着矿石资源大量的开采,遗留下大量的采空区。本文通过对湘西花垣县境内的铅锌矿采空区隐患处理技术研究,并结合当地的实际情况,提出"封堵+监测"联合治理方式处理复杂采空区,采用先进的微震监测技术实时监控采空区顶板稳定性,依据监测结果合理优化采空区封堵措施,实践表明该方案能够有效监测地压灾害,保障人员的安全。

With the massive exploitation of domestic ore resources, a large number of goafs had been left behind. In this paper, the hidden danger control technology of the lead-zinc mine goaf in Huayuan County, Western Hunan, was studied, and a combination harnessing method of ‘plugging＋monitoring’ was put forward to deal with complex goafs combining with the local actual situation, and advanced microseismic monitoring technology was used to monitor the stability of the goaf roof in real time, and plugging measures of the goaf were reasonably optimized based on the monitoring results. Practice showed that the scheme could effectively monitor ground pressure disasters and ensure the personnel safety.
