【Abstract】 Based on the characteristics of No.VII ore body of Xiadian Gold Mine, the improved schemes of sublevel caving without pillars of induced falling and setting footwall drifts to recover residual ores are researched and adopted. The integrated measures such as drawing combined with low dilution and cut-off grade and setting footwall drifts etc. are raised. Ore loss and dilution are reduced and controlled effectively, and better applying effect is obtained.更多还原
