针对呷村银多金属矿前期开采的剩余矿体进行了分类与讨论,并以该矿4160 m中段7线~9线之间的残留矿体为例,结合周边空区分布情况、地压变化情况,对该范围内存在的不同类型残留矿体的回收顺序、回采工艺以及采切工程做出了合理分析与布置,并就实施过程中的一般技术要求进行了说明.研究结果一方面解除了原矿山采用单一方式进行残矿回采的限制,将回采方式增加到5种;另一方面在对旧有工程的恢复利用基础上,进行新的采切工程布置,最终实现了采切比8.38 m/kt、53.11 m3/kt的良好经济效果.%In this paper,the remaining ore bodies in Gacun silver polymetallic mine are classified and discussed,and taking the residual orebody which is in 4160 m level between line 7 and line 9 as an example, combines with distribution of surrounding area and the situation of ground pressure,the reasonable analysis and arrangement are made for stoping sequence,mining technology and cutting engineering of different residual orebody existing in the area,the general technical requirements in process of implementing the plan are explained.The findings,on the one hand,lift the limitation of mining the residual ore in a single way in the original mine,increase the stoping method to 5 kinds;on the other hand,the new mining and cutting engineering layout are carried out on the basis of the restoration and utilization of the old works,and achieve a good economic effect of cutting ratio 8.38 m/kt,53.11 m3/kt.
