摘　　要：采场结构参数直接关系到采场自身的稳定性及开采过程的整体安全,选择合理的采场结构参数,有利于采场稳定,并提高开采速度。针对采场稳定性的问题,采用数值模拟的手段对采场结构参数进行优化,从开采过程中矿岩的位移、应力和塑性区等方面进行了详细分析。在保证安全的条件下确定了最优的矿块结构参数,为矿山规模化生产提供了有力的理论支撑。It is known that stope structure parameters have an impact on rock mass stability and mining safety. Namely, when choosing reasonable stope structure parameters, it is beneficial to ensure stope stability and improve recovery rate. In the paper, displacement, stress and plastic zone of ore and rock during mining are analyzed respec- tively by numerical simulation, and then the stope structure parameters are obtained. It can provide technical refer- ences for mass production.
