山西省大同煤田石炭二叠系主采煤中锗元素分布赋存特征及成矿前景预测
|
摘要
根据收集的煤炭勘查区钻孔测试数据及煤矿采样测试结果,对大同煤田石炭二叠系主采煤层山4号、3-5号、8号煤层煤中锗的含量进行统计并成图,研究分析了煤中锗分布特征及赋存特征,锗富集区分布于煤田北部,煤中锗主要以有机质结合存在,其富集区主要分布在低变质程度煤层中,低价煤中有机质含有较多官能团,可以与锗以整合物的形式结合。煤田北部四台煤矿和同忻煤矿这两个区域因各煤层煤中锗资源富集度高,成矿前景较好,可作为下一步重点勘查开发地区。
based on collected coal exploration area borehole tested data and coalmine sample tested results,carried out statistics and mapping for germanium content in main mineable coal seam Nos. S4,3-5 and 8 in Permo-Carboniferous coal measures,Datong coalfield. The distribution and hosting features of germanium in coal have been studied and analyzed. The germanium enrichment area is distributed in northern part of the coalfield low degree metamorphosed coal seams,mainly combined with organic matter. The organic matter in low ranked coal contained with more functional groups,can be combined with germanium in integrated forms. The Sitai and Tongxin coalmines in the northern part of the coalfield,because of high degree of germanium enrichment thus have better metallogenic prospect can be next step emphasized exploration and exploitation areas.
