摘要
河北矾山磷矿采矿方法为有底柱和无底柱采矿法相结合的一种新的采矿法,其采场结构参数选取正确与否,将直接影响该方法优越性的发挥。本文通过物理模拟放矿实验和电算模拟放矿实验验证了其结构参数选取的可行性和合理性,从而为该采矿方法在矾山磷矿的推广应用奠定了基础。
The mining method which will be used at Hebei Fanshan Phosphorus Mine is a new one combining the sublevel caving mining method with sill pillar and sublevel caving mining method without sill pillar.The selection of structure parameters of the stope will directly affect the elaboration of the advantages of this method. Based on physical modelling drawing test and computer simulation drawing test,it is proved that the parameters selected are feasible and reasonable,so as to lay a foundation for using the mining method at Hebei Fanshan Phosphorus Mine.
