摘 要:在采场结构稳定的前提下,为了降低矿石二次贫化,利用三维数值分析程序,模拟了乳山市金矿深部分别采 用留矿法和上向不胶结充填分层开采两种采矿方法,得出乳山市金矿在-485m水平以下,上向不胶结充填分层回采 方法是首选方案,并确定了该回采方法的矿房参数。In condition of ensuring stability of stope structure and reduce second impoverishment of ore, both mining methods were simulated by 3D numerical analysis programme. The first is shrinkage method. The second is sublevel fill stoping from bottom to top and its filling medium isn't cemented. It was found that the second mining method could reduce second impoverishment of ore effectively and improve safety production condition below level of - 485 m in the mine. Therefore, the second mining method is to be chosen. Based on above-mentioned research results, the parameters of the second mining method were determined.
