三道庄矿区单层采空区处理研究

Research on the Treatment Method of Single-layer Mined-out Area of Sandaozhuang Mine Area

介绍了三道庄矿区露天采场下部大量单层采空区的处理方法,给出了深孔崩落法安全参数,规范了空区探测、场地准备、穿孔、爆破及铲装施工要求,解决了采空区处理及残矿回收利用问题。

The treatment methods of signal-layers mined-out areas of Sandaozhuang open-pit mining area are introduced in detail, and the safety parameters of deep hole caving method are given. The con- struction requirements of cavity detection, site preparation, perforation, blasting and shovel loading are regulated. The research results of this paper solve the problems of mined-out areas treatment and residual ore recycling.
