摘要
与石油地质学领域比起来,煤地质学领域近十多年来显得有点"冷清"。燃煤过程中出现的环境污染问题以及煤作为油气源岩新认识的出现,又使相对"冷清"的煤地质学领域闪烁着一些"热点"。这些现在和今后可能成为持续的热点问题包括:隆重煤模式、煤系层序地层学、与环境保护有关的煤中有毒有害元素赋存和扩散规律、与煤成烃有关的富氢镜质体、树皮煤以及煤层气的成因和分布等。在国家自然科学基金资助的项目在,基本上都有优先考虑这些方面的内容。
Comparing with the field of petroleum geology,ir looks like a little'cold and cheerless'in that of coal geology in the last more than ten years.However the status of coal resources in our country' senergy constitution(nore than 70%),the emergence of the problem of environmental pollution during burning coal and the newly understanding of coal as a source rock for oil and gas,there are some'hotspots'glittering in the relatively'cold and cheerless'field of coal geology.These hotspot issues at present and in future possibly in- clude:the coal accumulation pattemsequence stratigraphy of coal measures,the occurrence and distribution pattern of harmful elements in coal which are related with the environmental protection and people's health, the genesis and distribution of hydrogen-rich vitrinite and the bark liptobiolite as well as the coal bed gas which are related with the hydrocarbon from coal et al.Projects involving these areas are supported by the Natural National Science Foundation nearly every year.These are listed and briefly summarized in this paper.
