我国煤系共伴生矿产资源综合利用研究进展

Research Progress on Comprehensive Utilization of Associated Mineral Resources in Coal-bearing Strata in China

煤炭是我国的基础能源,煤系共伴生矿产资源储量大、种类多,主要包括金属矿产、非金属矿产与能源矿产。加强煤系共伴生矿产资源综合利用符合国家能源资源加工利用重大需求。阐述了煤系金属矿产(锗、镓、铝、稀土元素)、非金属矿产(硫铁矿、高岭土、膨润土、耐火黏土、硅藻土、石墨)和能源矿产(铀矿、油页岩、煤系气、天然气水合物)的赋存状况、分布特征与加工利用研究进展,分析了“双碳”背景下煤系共伴生矿产资源综合利用面临的机遇与挑战,展望了延伸煤系产业链、聚焦关键技术开发、促进煤系共伴生矿产资源分类及内涵改革、完善矿业权设置管理的发展前景,为未来煤系共伴生矿产资源综合利用提供借鉴。

Coal is the basic energy of our country.The associated mineral resources in coal-bearing strata have many kinds and large reserves.It can be divided into metal minerals,non-metallic minerals and energy minerals.Deepening the comprehensive processing and utilization of associated mineral resources in coal-bearing strata is in line with the major needs of national energy resources processing and utilization.This paper expounded the occurrence,distribution characteristics,processing and utilization of metal(germanium,gallium,aluminum and rare earth elements),non-metallic(pyrite,kaolin,bentonite,refractory clay,diatomite,graphite)and energy minerals(uranium,oil shale,coal measure gas,natural gas hydrate)in coal-bearing strata,analyzed the opportunities and challenges faced by the comprehensive utilization of associated mineral resources in coal-bearing strata under the background of"Double-Carbon Policy"and looked forward to the development prospect of extending the coal-bearing strata industry chain,focusing on the development of key technologies,promoting the classification and connotation reform of associated mineral resources in coal-bearing strata,and improving the management scheme of mining rights.It provides a reference for the study of comprehensive utilization of coal measures associated mineral resources in the future.
