煤炭地质勘查中共伴生矿产资源的综合勘查研究——以内蒙古地区煤田中共伴生的锗、稼等矿床为例

Comprehensive Study on Coal Geological Exploration of Symbiotic and Associated Mineral Resources——Setting Symbiotic and Associated Germanium and Marry Deposits in Coal Mines in Inner Mongolia as an example

煤炭地质勘查揭露的含煤岩系中共伴生有金属矿产资源、非金属矿产资源和能源资源,加强含煤岩系中共伴生矿产资源的勘查可为国民经济建设提供更多的矿产资源具有重要现实意义和经济价值。如何在煤炭地质勘查中加强共伴生矿产资源的勘查与研究。文中列举了内蒙古自治区乌兰图与煤层共生锗矿床,锗品位平均244×10^(-6),锗金属量1 805 t;内蒙古自治区准格尔煤田与煤层共伴生镓矿床,镓平均品位44.8×10^(-6),保有镓金属量6.3×10~4t,预测锗金属量8.57×10~5t,该煤层还富集稀土元素,其平均含量为255×10^(-4)。内蒙古自治区近几年在鄂尔多斯东胜煤田含煤岩系下中侏罗统延安组的煤炭地质勘查中发现并勘查了一处世界级铀矿床,从而改变了我国铀矿资源状况。因此,在煤炭地质勘查中极需加强含煤岩系中共伴生矿产资源的勘查与研究,并就此问题提出了若干建设性的意见。

Coal geological exploration revealed the coal-bearing rock series of the communist party of China associ- ated with metal mineral resources, non-metallic mineral resources and energy resources, strengthen the coal-bear- ing rock series of the communist party of China of associated mineral resources exploration can provide more mineral resources for the national economic construction has important practical significance and economic value. How to strengthen in coal geological exploration of associated mineral resources exploration and research. This paper enu- merates the Inner Mongolia autonomous region were ulam figure and symbiotic germanium deposits of coal seam, the average grade of germanium 244×10^-6, germanium metal reserves of 1805t; Inner Mongolia autonomous region must be associated with coal, coal gallium deposits, gallium average grade 44.8× 10^-6, gallium reserves metal re- serves of 6.3×10^4t, forecasts 8.57×10^5t resources, the coal seam also enrichment of rare earth elements, the aver- age content of 255×10^-4. The Inner Mongolia autonomous region in recent years under the erdos dongsheng coalfield coal -bearing rock series in the jurassic yanan group found in coal geological exploration and the exploration of a world-class uranium deposits, which changes the uranium resources in our country. So, exploration and research of associated mineral resources in coal-bearing rock series should be strengthened. Relative countermeasures and sug- gestions have been put forward as well.
