Application of medium-length hole drilling equipment in non-ferrous mines in China;

According to the actual situation of a Mo mine which will employ multi-stage mining and the occurrence morphology of orebody which is deep and large,the paper introduces sublevel stoping mining method drilled by mid-deep borehole drilling machine and loaded by electric-rake.

According to the mining conditions of inclined,broken orebody with medium thickness and lower grade in Nalin Gold Mine, sill-free sublevel caving method and long and medium hole drilling and blasting were applied in research experiment.
