矿产资源潜力评价中成矿地质体体积法及参数确定方法探讨

摘要

根据西藏矿产资源潜力评价的实践成果,针对第一批“全国矿产资源潜力评价”项目中资源量估算过程中存在的问题和不足,结合实践和认识,系统总结已有潜力评价工作中资源量估算过程中的经验和方法,进一步完善了全国矿产资源潜力评价中资源量估算流程和方法,提出了成矿地质体体积法中面积、延深、相似系数等重要估算参数的确定思路和方法.在综合矿产资源潜力评价中资源量估算方法和西藏矿产资源潜力评价实践成果的基础上,应用VBA编写而成的资源量估算辅助工具软件包“地质体积法预测辅助系统”,可以很好地应用于矿产资源潜力评价中资源量估算,为新一批全国矿产资源潜力评价项目工作以及其它相关矿产勘查和预测工作提供帮助和参考意义.%In view of the problems and defects existing in process of resource reserve estimation in the first batch of the national mineral resources potential assessment project (MRPAP) in China, the experience and methods for process of resource reserve estimation is systematically summarized according to the results and practice of the tibetan mineral resources potential assessment project. Processes and methods of resource reserve estimation in MRPAP are further improved, and the paper presents guideline and method of determining parameters in the Metallogenic geologic body volume method, such as acreage, down dip extension, similarity coefficient. Base on the combination of resource reserve estimation method in MRPAP with the results and practice of the Tibetan MRPAP, "Prediction auxiliary system of geologic volume method" (PASV) is programmed by using VBA, which is a auxiliary software toolkit for resource reserve estimation. It has been confirmed that the PASV can well applied in resource reserve estimation of MRPAP, and it is expected to provide help and reference significance for the new batch of the national mineral resources potential assessment project in China and other relevant mineral exploration and prediction.
