所有地下矿山都有许多影响其总利润的限制因素。当矿山利用有限的劳动力处理过爆造成的额外岩石量、完成额外地下支护任务时,生产活动被非生产工作取代。如果过爆引起矿石品位降低,采矿经济效益会受到更进一步的影响。回顾了矿山一直在采用的创造良好环境。有助于成功控制过爆的组织制度。 All underground mines have a number of constraints that affect their total profit. Production operations were replaced by nonproductive jobs when the mine completed the additional subsurface support tasks using a limited amount of labor to deal with the explosion. If over-blast causes the grade of ore to be reduced, the economic benefits of mining will be further affected. Recalling the good environment the mine has been using. Organizational systems that help control overblown issues.
