充填采矿法应用范围的扩展

Expansion of Application Sphere of Cut-and-fill Mining Method

论述了充填法采矿的应用范围 ,已从适用于中厚急倾斜矿体发展到适应复杂多变的矿体。在中厚倾斜矿体的开采过程中 ,改变人道和溜井在采场面的相对位置 ,可适应矿体的变化 ,降低贫化率。通过主采场探边扫盲 ,在增加很少掘进量的基础上 ,扩大了采场回采面积。对顶底柱进行回采 ,可多回收矿产资源。

The application scope of cut-and-fill mining is described which has extended from medium thick steeply inclined orebody to complex variable orebody.In the mining process of medium thick steeply inclined orebody,changing the relative position of manway and pass on the stope face to suit the change of orebody can reduce the dilution rate.The extraction of blind orebodies in the main stope may expand the extraction area with only very little drivage work.The recovery of bottom and floor pillars can increase the recovery of mineral resource.The application of cut-and-fill mining method in Fenghuashan Copper Mine has achieved good results.
