本文将正交试验设计和三维有限元数值模拟方法用于优化河北某铁矿缓倾斜中厚矿体的盘区开采顺序,在底板采准巷道稳定性的目标下,获得最优盘区开采顺序为斜对角线正台阶式开采顺序。
In this paper, the orthogonal experimental design and three-dimensional finite element numerical simulation method is used to optimize the plate mining order of moderately inclined orebody with a moderately inclined thickness in a certain iron mine in Hebei Province. Under the goal of the stability of the roadway adopted by the floor, the optimal panel mining sequence Oblique diagonal is the stage of mining order.
