| 摘 要： | 根据乳山市金矿深部矿藏的赋存条件、围岩特征和地压显现特点,以采场结构的稳定性为前提、降低矿石二次贫化为目的,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的优劣。认为在乳山市金矿在-485 m水平以下采用上向不胶结充填分层回采方法可以有效地降低矿石的二次贫化和改善安全生产条件。该研究成果已获得工程实践的验证。图2,表3,参10。

| Abstract: | According to occurrence condition and surrounding rock feature as well as ground pressure character of depth mineral resources of Rushan city gold mine, both shrinkage method and no-cementupper extraction with stowing of slicing method of more units was simulated by 3D numerical analysisprogramme. A premise of stability of slope structure and an aim of reducing second impoverishment of ore were considered when two a-bove-mentioned mining methods were simulated. It is regarded that no-cement upper extraction with stowing of slicing method of more units may effectively reduce second impoverishment of ore and improve safety production condition below level of-485m in Rushan gold mine. The research result was verified by engineering practice. 2figs. , 3tabs., 10refs. |
