元宝山露天煤矿采空区治理方案

摘要

由于小煤窑越界开采,在露天采区北部形成面积约为1.49 km2的采空区,这些采空区位置不明,开采程度不详,为露天矿长远发展带来了极大的安全隐患.为了确保露天矿高效、安全生产,结合露天矿实际情况,制定了采空区治理方案,为其他露天矿处理采空区提供参考与依据.%Because of the small coal mines cross-border exploitation, the northern open-pit mining area forms about 1.49km2 goaf .These goafs are not clear and the mining degree is unknown, which has brought great security risks to the long-term development of open-pit mines. In order to ensure efficient and safe production of open-pit mines, combining with the actual situation of open-pit mines, the mine formulates scheme of goaf treatment, which provides reference and basis for other open-pit mines.
