中文摘要:
      为克服某矿深部矿体开采过程中地压难以管理的问题,实现金属矿体的安全高效开采,基于协同开采理念,设计了三种不同开采顺序方案。运用Phase2数值模拟软件建立矿体开挖模型,分析了不同回采顺序下矿体围岩应力和位移的变化规律。研究结果表明:随着间隔矿柱数的增加和高强度充填体范围的扩大,采场地压得到有效控制。其中,方案1开采顺序优化程度较低,方案2与方案3开采顺序优化程度较高;在此基础上,本文综合技术、经济两种指标构建出深部矿段开采顺序优化的协同测度模型,并计算出三种回采方案的协同度分别为0.063、0.178、0.196,确定了方案3为最优开采顺序方案。
英文摘要:
      In order to over come the problem of ground pressure management in the process of mining for deep orebody and realize the safe and efficient orebody mining.The optimization schemes of three different mining sequences are designed basing on synergetic mining conception.By using numerical simulation software Phase2,the model of orebody excavation is built.The stress and displacement time-varying effects of the different scheme is analyzed by numerical simulation.The results show that the stope ground pressure is effectively controlled as the increase in the number of route interval and the expansion of high intensity backfillSscope.Among them, the degree of mining sequence optimization of the first scheme is low and the second and third scheme is high.On this basis, this paper establishes a synergetic degree measure model for mining sequence optimization basing on the technical and economic indices.The synergy degree values of the three schemes are 0.063,0.178 and 0.196 separately.The optimal scheme is established and it is the scheme 3.
