摘要
对于崩落矿石和围岩的采矿法，需要借助于预测矿块的各种放矿制度和结构参数下的放矿中矿石回收率和贫化率去优选矿块的放矿制度和结构参数。将物理模拟放矿和随机模拟放矿结合起来，能更好地再现实际放矿．新提出的向一些高程削高峰的矿块放矿制度有时是经济上最优的，而且不要求以最多的次数去开关放矿点．优选矿块的放矿制度和结构参数时应根据该矿块的自然和社会条件进行模拟放矿和经济计算。
For caving mining, must optimize the ore drawing regime and structure parameters of a block with the aid of forecasting ore recovery and dillution during ore drawing from the block under different ore drawing regimes and structure parameters of the block. In combination of physical simulating with random simulating of ore drawing can reproduce practical ore drawing better. Newly proposed ore drawing regime of a block with lowering peaks to several altituds sometimes is economic optimum and does not ask to open and close drawpoints by the most times. During optimization of an ore drawing regime and structure paramenters of a block, ought to carry on ore drawing simulating and economic calcultating by natural and social conditions of the block.
