通过运用加拿大rocscience研究所研发的二维有限元数值模拟软件Phase2对凡口铅锌矿较典型的N4-5采场逐步进行了动态模拟分析。通过分析,准确模拟了采场回采过程中的应力分布及位移变化情况,为优化采场结构参数和指导地压控制提供了可靠的依据。
By using the two-dimensional finite element numerical simulation software Phase2 developed by Canadian rocscience Institute, the dynamic simulation analysis of the typical N4-5 stope in Fankou lead-zinc mine was carried out step by step. Through the analysis, the stress distribution and the displacement change during the process of stope mining are accurately simulated, which provides a reliable basis for optimizing stope structure parameters and guiding ground pressure control.
