摘要
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, orthogonal test design and three dimensional finite elememt numerical simulation method (FFM) are applied to optimization of panel mining sequence for flat-dipping,middle-thick orebody in an iron ore mine, Hebei Province. For the stability of openings in foot wall, the optimized panel mining sequence is heading-and -stope method in obligue mining sequence.
