摘要： 移动概率赋值问题至今没有一个很好的解决方法,现今的放矿仿真使用的移动概率仍然为传统的移动概率赋值方法,并且是始终不变的,已经不能适应现今矿山的仿真要求.基于上述情况,通过多次SLS放矿实验后,对移动概率问题提出商榷意见,即对k取不同的数值进行仿真的放矿,可以得到不同的回收指标,也就是反映了不同的矿石松散性,使仿真结果更接近于实际情况,同时也简化了9块概率赋值过程.

Abstract: Valuation of movement probability has remained difficult to solve up to now without appropriate solution given to it. Today the movement probability used in ore-drawing simulation is still with traditional valuation all through, but it is unadaptable to mining simulations nowadays. So, after the SLS ore-drawing tests carried out for many times, a discussion was made on the movement probability problem and some views were put forward, i.e. assigning different values to k during ore-drawing simulation so as to get different recovery indices. The different ore loosennesses are thus reflected to enable the simulation results to be closer to actual condition and at the same time, to simplify the valuation process of the nine-block probability.
