摘要
运用三维有限元模拟计算方法对某集团铜镍矿一个分层采场地压进行了数值模拟计算分析，并与现场观测结果相互验证，得出随着工程的进展，动态地压变化结果。为优化采场参数和回采工艺，实现高效安全生产提供了依据。
Abstract
Numerical simulation calculation analysis was done on stope ground pressure of a layer of cuni ore of a group by using 3d finite element simulation calculation method, and verified with site observation result, changing result of dynamic ground pressure with the development of engineering was obtained, which provided basis for optimization of stope parameters and mining technology and efficient safe production realization.
