摘　　要：讨论了失稳倾向矿床的采场结构参数的优化问题,以平均能量释放率为优化目标,将数值模拟与正交设计方法相结合,提出了失稳倾向矿床采场结构参数优化的一般方法。采用作者改进的优化方法与程序,对某失稳倾向矿床的采场结构参数进行了优化研究,获得了该矿床开采设计较优的采场结构参数。并用能量释放理论进行分析,讨论了其稳定性,为矿山实际生产提供了可靠的理论依据。The paper discusses the optimization of the stope structural parameters for deposits with instability tendency. With average energy release rate as the optimization target, a general method for optimizing the stope structural parameters for deposits with instability tendency is proposed based on the combination of numerical modeling and orthogonal design. By using the optimization method and procedure modified by the authors, the stope structural parameters of a deposit with instability tendency are optimized for the mining design of this deposit. Its stability is also studied by adopting energy release theory, providing a reliable basis for the practical mining.
