摘要
介绍了ＲＦＰＡ′９８ 数值模拟计算软件的特点和计算方法，并结合湘西金矿深部无间柱连续开采技术研究课题，建立了采场数值模拟计算模型，分析了采场的稳定性．通过计算，准确模拟了采场回采过程中的应力分布情况，为优化采场结构参数和指导采场地压控制提供了可靠的理论依据．
This paper presents a calculating method and describes characteristics of RFPA′98 numerical simulation software. Based on the research of Continuous Mining Technology Without Midwall in depths of Xiangxi Gold Mine, the calculating model of stope was established, and the stability of the stope was calculated and analysed. The results showed the situation of rock stress distribution during mining of stope and provided theoretic basis for optimizing stope structure parameters and instructing the control of rock stress.
