摘要
针对矿体情况,原设计为上向式胶结充填采矿法,但在回采过程中矿体的形态及其品位发生了较大变化,因此在充填体上部将局部块段改为房枉法开采,从而节约了成本,获得了较好的经济效益。
Based on the ore body occurrence,the former designed mining method was upward consolidated fill sloping.Because the ore hody form and the ore grade changed greatly with the sloping,the room-and-pillar method was used to parts of the ore block on lop of the filling hody.It reduced the cost and gained good economic benefit.
