某铜矿在矿区南部探边扫盲时 ,探获了与原主矿体赋存状态截然不同的倾斜薄矿脉 ;其产状变化大 ,开采条件较复杂。根据矿脉地质条件的不同 ,探讨了改进型的采矿方法 ,即房柱全面矿块空场采矿法和分段空场留矿法 ,并获满意效果。该采矿方法的成功应用 ,将对该矿山或同类倾斜薄矿脉的开采具有一定的指导意义。
When a copper mine explores the edge in the southern part of the mining area, it is found that the inclined thin vein has a very different shape from that of the original host ore body. The occurrence of such a copper deposit changes greatly and the mining conditions are complicated. According to the different geological conditions of the veins, the improved mining methods are discussed, that is, the method of empty field mining with full blocks and columns and the residual mining method in the sub-field are satisfied, and satisfactory results are obtained. The successful application of this mining method will be of certain guiding significance for the mining of this type of mine or similar inclined thin vein.
