阿希金矿采空区对地表构筑物影响分析及监测方案研究

Study on the Influence of Goaf on Surface Structure and Subsidence Monitoring in Axi Gold Mine

针对阿希金矿开采技术条件及采空区分布情况,就1385m中段以上采空区对地表影响进行了数值模拟分析,发现在地表形成位移约为1cm的影响区域,其东西范围约120m,南北范围约400m,主要集中在南北露天坑之间。地表岩移监测采用静力水准仪、拉线式位移计、全站仪三种手段对岩移范围进行监测,目前,该监测系统已进入建设实施阶段。

Based on the technical conditions of Axi gold mine and the distribution of goafs,the numerical simulation analysis on the surface influence of goafs above 1 385 m was carried out. It was found that the affected region with a displacement of about 1 cm was formed on the surface,with an east-west range of about 120 m and a north-south range of about 400 m,which was mainly concentrated between the seventh vein plate chamber and the water tower. The monitoring of subsidence was carried out by three means: static level,pull line displacement meter,total station. At present,the monitoring system has entered the construction and implementation stage.
