大宝山采空区治理研究

Study on Goaf Management in Dabaoshan

大宝山矿由于长期地下开采以及民窿偷采,形成了大量的井下采空区,对露天生产构成了严重威胁.为保证矿山安全生产,结合矿山地质状况及采空区分布情况,在采空区钻探、采空区扫描、采空区稳定性微震监测的基础上,采取了有效方法,成功处理好威胁露天作业的采空区,消除了重大安全隐患.

A lot of goafs have been formed in Dabaoshan Mine due to underground and civilian mining which will give great threat to the opening operation. On the goaf zones, the effective goaf management is given based on drilling investigation and scanning and goaf micro earthquake monitoring and in combining with the mine conditions and the goaf distribution for safety mining, which successfully controls the threat of opening operation in the goafs and eliminates the major hidden danger.
