| Abstract: | Dongguashan Copper Mine is a deep mine which is complex and difficult for mining. In order to strengthen the safety of mining and ensure its capacity, large-diameter long-hole sublevel open stoping with post filling method is selected. Different groove cutting ways impact stope production capacity differently. Different ways of groove cutting are studied to increase the production capacity, and several efficient groove cutting methods that are fit for different stope height of Dongguashan Copper Mine are gi... |
