摘要
结合程潮铁矿实际采场情况,利用PFC3D软件,对放矿过程进行数值模拟实验,验证了椭球体放矿理论。根据数值模拟结果,对采场结构参数进行优化,分析不同放矿步距下矿石回收情况,结合该矿的生产现状,提出现行放矿步距扩大至3.0m的建议。
Combined with the actual situation of Cheng-chao Iron, numerical simulation of ore drawing experiment was carried out by means of PFC3D software, and the ellipsoid drawing theory was verified. According to the simulated re- suit, the stope parameters were optimized, and ore recovery under different ore steps was analized. It is concluded that the existing ore step should be expanded to 3.0 m under the current production of thismine.
