对能源金属矿产资源基地调查评价基本问题的探讨r——以四川甲基卡大型锂矿基地为例

摘要

Energy metallic minerals are significant and irreplaceable in the energy field. To build large metallic mineral base as a national goal is also a new thing in investigation and assessment. Lithium as a 21st century energy mineral will play an important role in solving the bottleneck problems such as energy crisis and environmental protection in China. In Jiajika of western Sichuan, there exist rich lithium resources and superior metallogenic conditions. Based on the working practice of comprehensive investigation and assessment in Jiajika large lithium mineral resource base, this paper discusses the fundamental problems which will emerge in investigating and assessing the "energy + metal" type mineral resources base, such as the target tasks, basic principles, project basis, innovation drive, technical route, and work content. This can not only offer reference for work deployment in the same kind of large mineral resource bases but also provide the basis for scientific decision and reasonable development of lithium resources. To carry out the investigation and assessment in large energy metallic resources base dominated by lithium in western Sichuan Jiajika can increase the degree of mineral geology survey and reliability of the reserves, further investigate resources base, drive the exploration, provide resources guarantee for establishing large exploration and development base to provide resources, and establish a demonstration for the survey evaluation in the whole western Sichuan region. Innovation drive including finding out occurrence regularity of lithium, lithium isotope and associated components for improving the comprehensive research and utilization degree will provide a scientific basis for the efficient development of the energy metal in the field of high and new technology. The overall planning and rational deployment can not only turn resource advantage into economic and social advantages and benefit the local people but also supply scientific basis for the construction of the western Sichuan region into a new energy base so as to lead the development of emerging industries.%能源金属矿产是指可在能源领域发挥重要作用的金属矿产资源,而大型能源金属矿产基地作为国家目标开展调查评价,也是新事物.四川西部甲基卡一带锂资源十分丰富,成矿条件优越,而锂作为21世纪的能源金属,将为解决我国能源危机、环境保护等瓶颈问题发挥重要作用.本文通过对甲基卡大型锂矿资源基地综合调查评价的工作实践,探讨了在"能源+金属"类矿产资源基地进行调查评价时所遇到的基本问题,包括目标任务、基本原则、立项依据、创新驱动、技术路线、工作内容及其他应注意的问题,为同类大型矿产资源基地的工作部署提供参考,同时也为科学决策、合理开发锂资源提供依据.通过川西甲基卡一带以锂为主大型能源金属资源基地的调查评价,不但可提高矿产地质调查程度和资源储量的可靠程度,进一步摸清资源家底,为带动整装勘查、建设大型勘查开发基地提供资源保障,而且可以为整个川西地区能源金属的调查评价提供示范;通过创新驱动包括查明锂、锂同位素及其共伴生组分的赋存规律,提高综合研究和利用程度,为能源金属在高新技术领域中的高效开发提供科学依据;通过统筹规划,合理部署,有序推进,不但可将资源优势变成经济社会优势、造福地方百姓,也可以为把川西地区建设成为新能源基地、引领新兴产业的发展提供科学依据.
