摘要
我国是一个资源匮乏的大国,针对井下高斗留矿法采场和小中段空场法采场电耙道底板至切割层底板之间的设计永久损失部分矿体,通过确定合理的技术方案,成功回收。
China is a big country with limited resources. According to the design of permanent losses between the float of cutting layer of high trolley shrinkage method for underground stope mining method and small -stage open stope method and electric rake road , the reasonable technological solution was identified, and the ore was recoveried successfully .
