摘要
基于风险分析的商业性找矿预测新方法主要限于针对矿山深部和外围找矿预测与风险投资中的商业性矿产勘探。从风险分析和经济地质学角度对以往研究成果进行系统总结,认为成矿成晕模式与地质地球化学找矿预测系统、构造地球化学方法、矿体探采对比、广度搜索选优评价(矿点与异常成矿概率法)、深度解剖评价与定量预测等技术方法在金属矿山(床)找矿预测中应用前景广阔,矿物地球化学、岩相学亚相-微相填编图等新预测方法完善后可广泛推广应用。基于风险分析的商业性找矿预测方法技术不断发展,有助于满足境外矿产勘查迅猛发展和矿业权交易量增加的商业性矿产勘查新局势需求,推动矿产勘查和开发项目现代管理水平的提升。
The new ore prospecting methodologies based on risk analysis in commercial ore exploration and assessments are to focus on ore prospecting in the vicinities and deep parts of metal mines and on the venture capital investment in commercial ore exploration and assessments. We have systemically reviewed the achievements in ore prospecting from the views of risk analysis and economic geology, and summed up the following methodologies that can be widely used in ore prospecting for metal mines： those are the patterns of oreorming and geochemical halo-forming and the related predicating system of geology-geochemistry; the tectonic geochemistry; the balance sheets of exploration-exploitation of orebody; the optimization of occurrences and anomalies in the scope study, such as mineralization probability of occurrences and anomalies; the extensive assessments and quantitative predication. The mineral-geochemistry and the sublithofacies and microlithofacies mapping of lithofacies may also be broadly applied for ore prospecting and predication but only after making some improvement. With the development of ore prospecting methodologies based on risk analysis in commercial ore prospecting and assessments, the demands of the drastically increasing tasks of commercial ore-exploration overseas can be steadily met. Thereby the management of ore exploration and exploitation will be promoted in the future.
