煤炭资源勘探中共伴生稀有元素的综合勘查研究

Study on Integrated Prospecting of Paragenetic and Associated Rare Elements during Coal Resource Exploration

含煤岩系中共伴生有多金属和非金属等矿产资源,其中稀有元素在特殊地质条件下也可能富集,达到工业品位;个别元素(如锗、铀)已经被开采利用。通过列举内蒙古乌兰图嘎煤矿-锗矿床、准格尔煤田与煤层共生的镓,以及二连盆地群和鄂尔多斯盆地含煤岩系里的铀矿床等煤系伴生矿床实例,表明在煤炭地质勘查中需要加强煤层和含煤岩系中稀有元素资源的勘查与研究,并就此问题提出了若干意见。

In coal-bearing rock series have paragenetic and associated polymetallic and nonmetal mineral resources existed. In which,some rare elements can be enriched amount to industrial grade under specific geological condition. Particular elements（such as germanium, uranium） have already exploited and utilized. The paper has enumerated instances of Urant coal-germanium deposit, paragenetic gallium with coal in Jungar coalfield, uranium deposits in coal-bearing rock series in Erenhot basins and Ordos Basin etc. all in Inner Mongolia. The cases have indicated that during coal geological exploration should strengthen prospecting and researches on rare element resources in coal seams and coal-bearing rock series. On this issue, some suggestions put forward.
