摘要
蒙特卡洛模拟法是一种概率抽样的方法,它是利用模型区内已知矿床资源量的分布曲线,通过抽样实验模拟出该区在某种概率意义下具有的资源潜力的方法。通过对辽宁省11个矿带、16个矿田层控碳酸盐岩型未知铅锌、银矿床(点)的资源潜力模拟,获得了省内层控碳酸盐岩型铅、锌、银的资源潜力。在模拟过程中所使用的评价方法及所应用的前提条件是成功的,其所获得的层控碳酸盐岩型铅锌、银矿产资源潜力是可信的。本文只讨论第Ⅳ矿带及第16矿田的资源潜力。
Monte Carlo simulation is a method of probability random sampling which simulates the potention of mineral resources under probability through random sampling experimen by use of the distribution curves showing known mineral resource quantity in the model region.The resource potention of stratabound carbonate-type Pb-Zn-Ag deposits in Liaoning province is acquired through respectively simulating unknown resource petontions of 11 ore belts and 16 ore fields in Liaoning province,in which Ⅳ ore belt and No.19 ore field are the examples showing the simulating process. During the simulation,the evaluating method and prerequisite conditions are feasible and the acquired resource potention of stratabound carbonate-type Pb-Zn-Ag deposits for Liaoning province is reliable.
