摘要
钍是除铀以外的另一种核燃料,钍基熔盐堆已被列入第四代核电技术的堆型之一。近年来,随着钍资源开发应用技术的突破,为钍资源调查评价工作带来了发展机遇和挑战。本文归纳总结了中国在钍资源调查评价、潜力预测和成矿理论方面的研究进展,划分了中国的钍成矿区带和钍矿成因类型,构建了各成因类型典型矿床的成矿模式,为钍资源基础理论的研究奠定了基础;建立了钍资源调查评价方法和数字化远景预测技术,为中国钍资源潜力评价工作提供了技术支撑;剖析了中国钍成矿特征和成矿机理;展望了中国可利用类型钍资源的开发前景,分析了目前钍资源调查评价工作中存在的问题;为今后钍资源勘查工作部署提供依据。
Thorium is another nuclear fuel other than uranium,and thorium-based molten salt reactors are one of the reactor types of the fourth generation of nuclear power technology.In recent years,breakthroughs in the development and application of thorium resources have brought development opportunities and challenges to the investigation and evaluation of thorium resources.This paper summarizes the current research progress of thorium resources in China's investigation and evaluation,potential prediction and metallogenic theory:it divides the thorium metallogenic belts and thorium genesis types in China,and constructs the metallogenic models of typical deposits in different genetic type,which lays a foundation for the research of the basic theory of thorium resources.The investigation and evaluation method of thorium resources and the prediction technology of digital telescope were established,which provided technical support for the potential evaluation of the thorium resources in China.The metallogenic mechanism of thorium was analyzed.It looks forward to the development prospect of available types of thorium resources in China,and analyzes the problems existing in the investigation and evaluation work of thorium resources.It provides a reference for the future deployment of thorium resource exploration and development.
