摘　　要：文章介绍了以含矿网格单元为统计单位、并与找矿信息量法结合的蒙特卡洛矿产资源潜力评价方法的原理和工作步骤,以及用该法进行丹池锡多金属成矿带锡矿矿产资源潜力评价工作案例,表明该法可以把评价工作区的矿产空间分布信息、成矿模式和找矿模型、成矿-找矿空间信息引入蒙特卡洛方法中,无需人类专家估计矿床个数,减少了工作步骤,提高了工作效率和自动化程度,减少了因人为主观性而造成的评价误差。This paper gave an introduction to the principles and workflow of Monte-Carlo method for mineral resource potential which used ore-bearing grid cell as statistic unit and was integrated with prospecting information method.Then the paper cited a case of Danchi Sn polymetallic deposit which applied this method in its assessment of the mineral resource potential of tin.It indicates that this method can import the information about the distribution of mineral resource,metallogenic mode,prospecting model,metallogenic-prospecting space of the appraisal area into Monte Carlo method.The number of the deposits is no longer required to be estimated by human experts.With less workflow steps the efficiency and automaticity are enhanced,and the assessement errors caused by subjectivity are reduced.
