摘要

摘要: 基于全国煤炭资源潜力评价和全国特殊及稀缺煤炭资源调查项目成果，结合前人的研究，采用保有储量加权平均法，分析我国不同省份、不同成煤时代煤炭资源的挥发分产率和焦油产率以及特高挥发分、特高油产率煤的分布和成因。结果显示：我国煤炭资源的挥发分产率储量加权平均值为30.27%，以中高-高挥发分煤为主，焦油产率储量加权平均值为7.66%，以富-含油煤为主；我国特高挥发分、特高油产率煤的保有资源储量约占全国煤炭保有资源储量的0.9%，主要为褐煤、长焰煤、气煤和气肥煤；含有腐泥煤和腐植腐泥煤夹层的煤和残植煤因富含壳质组分具有较高的挥发分产率和焦油产率；对于同一煤类，挥发分产率和焦油产率都与氢含量和氢碳原子比呈正相关关系。

Abstract: Based on the research results of Chinese potential coal resource estimation and Chinese special and rare coal resource investigation, and combining with previous studies, the volatile and tar yield of Chinese coal resource in different provinces and geological ages were discussed using the calculation method of weighted average of recoverable deposits. The distribution and genesis of super high volatile and tar yield coal in China were researched. The results show that the weighted average of volatile and tar yield of Chinese coal resource is 30.27% and 7.66%, respectively. The high-medium and high volatile coal and rich and low tar coal dominate. The super high volatile and tar yield coal occupies about 0.9% of the total recoverable deposits of Chinese coal, and they are primarily brown coal, long flame coal, gas coal and gas-fat coal. The coal with sapropelite or humossapropelite sandwich and the liptobiolite have higher volatile and tar yield because of rich liptinite components. The correlations between the volatile and tar yield and hydrogen content and hydrogen carbon atom ratio are positive for the same coal class.
