| Abstract: | Wa-Sun-Jia mine field of Bei-Jie Gold Mine belongs in altered rock type gold deposit.Controlled by fractured structure and presented as a vein deposit, its orebody is extremely broken in poor stability. Directed against these characteristics, the sublevel open stope method is employed in the experiment, from which the better techno-economic result is obtained. |
