摘要
通过研究和优化河北省矾山磷矿Ⅱ号矿体的结够参数,可以提高采场稳定性、采矿效率、矿石回收率及确保矿山生产安全.对于Ⅱ号矿体所采用的采矿方法,拟使用方形矿柱,对其采场结构参数中的点柱宽度、点柱纵向间距和横向间距这3个参数进行优化,运用数值模拟与正交试验相结合的方法得到采场结构参数的最优方案.通过此次的采场结构参数优化研究使矿山矿石的损失率、贫化率和采准工程量降低了,矿山开采的回采率和经济效益得到了一定的提高.在矿山矿石资源的回收及利用方面为其它类似结构的矿山提供了参考意义.
In order to improve the stability of stope, ensure the security of mining production, increase mining efficiency and the rate of ore recovery, the stope structure parameters of vanadium phosphate rock mountain Ⅱ# ore body in Hebei Province needs to be optimized. For the mining method of Ⅱ#ore body, we use square pillar to optimize the stope structure parameters of point pillars width, longitudinal spacing and lateral spacing. We also use numerical simulation, and orthogonal experiment stope structure parameters are obtained by the combination of the optimal solution. Through the stope structure parameters optimization research, the mine ore loss rate, dilution rate and collect accurate quantity are reduced, and mining recovery rate and the economic benefits have been improved by the stope structure parameters optimization research. Thus, it has provided references for other similar structures of the mine in the mining of mineral resources recycling and utilization.
