通过系统分析影响矿产资源勘查风险的基本因素 ,对前人确定勘查风险系数的方法———费用效益法、概率统计法进行了全面的评述 ,认为在实际操作上存在较大的困难 ,计算结果的准确性并不可靠。从统计地球化学理论出发 ,考查了矿产资源勘查和开发全过程中技术、经济参数对投资效果的影响 ,推导出矿产勘查投资利润率的计算公式 ,并将其与安全利率相比较 ,达到计算矿产资源勘查风险的目的 By systematically analyzing the basic factors that affect the exploration risk of mineral resources, this paper makes a comprehensive review of the methods for determining the risk factors of prospecting --- the cost-benefit method and the probability-statistics method, and finds that there are great difficulties in practical operation. The calculation results The accuracy is not reliable. Based on the theory of statistical geochemistry, this paper examines the impact of technical and economic parameters on the investment effect in the whole process of exploration and development of mineral resources, and deduces the formula for calculating the profit rate of investment in mineral exploration and compares it with the security interest rate to calculate the mineral The purpose of resource exploration risk
