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.
含煤巖繫中共伴生有多金屬和非金屬等礦產資源,其中稀有元素在特殊地質條件下也可能富集,達到工業品位;箇彆元素(如鍺、鈾)已經被開採利用.通過列舉內矇古烏蘭圖嘎煤礦-鍺礦床、準格爾煤田與煤層共生的鎵,以及二連盆地群和鄂爾多斯盆地含煤巖繫裏的鈾礦床等煤繫伴生礦床實例,錶明在煤炭地質勘查中需要加彊煤層和含煤巖繫中稀有元素資源的勘查與研究,併就此問題提齣瞭若榦意見.

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 germa-nium, 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 ele-ment resources in coal seams and coal-bearing rock series. On this issue, some suggestions put forward.
