摘要
四老沟矿因侏罗纪煤炭资源衰竭,既要积极寻找新的煤炭资源,又要进一步精采细采,尽量回收煤炭资源延长矿井服务年限。因此,借鉴上覆采空区极近距离开采经验,结合先进的物探手段及钻探技术,探明小窑破坏区情况,成功回收小窑破坏区的煤炭资源17万t,有效延长了矿井服务年限。
Since the coal resources of Jurassic Period is exhausting, Silaogou Mine seeks for the new coal resources. Meanwhile, the mine recycles the coal recourses to achieve more accurate and refined mining in order to prolong the service life. Therefore, on the extra-close mining experience of the upper goal, the study investigates the failure situation caused by mini coal mines using advanced geophysical prospecting method and drilling technology. It has recovered 170,000t coal recourses from the failure zone of mini coal mines and prolonged the service life of the mine.
