    Study on the comprehensive recovery scheme of residual ore resources in Gacun silver polymetallic mine

    • In this paper,the remaining ore bodies in Gacun silver polymetallic mine are classified and discussed,and taking the residual orebody which is in 4 160 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.
