摘要
中国炼焦煤资源具有以下特点:煤炭资源丰富,但炼焦煤资源所占的比例并不高;煤炭资源分布广泛,全国29个省(自治区)都赋有炼焦煤,可是炼焦煤资源主要集中分布在为数不多的地区;炼焦煤种品种齐全,但分布不均匀,其中气煤和1/3焦煤在炼焦煤查明资源储量中占较大比例,焦煤与肥煤是炼焦的主力煤种,但占比例较小;目前华北聚煤区东缘的几个大煤田正以每年约15m的速度向800m延伸,个别煤矿的开采深度已到1 000m,勘查深度也达1 200m,因此,研究深部煤的变质作用意义深远。根据煤的深成变质作用理论,我国华北东缘诸多煤田的深部煤质有可能变好,有可能赋存大量的肥煤、焦煤和瘦煤等稀缺资源,该预测结论若获得验证,将有利于解决我国主要焦煤资源紧缺瓶颈,为未来我国经济建设提供可靠的资源保障。
The resource of coal for coking in China has some features as follows： abundant coal resources with low proportion of coal for coking; wide spread of coal for coking in 29 provinces （autonomous regions） but concentrated only in small number of mining areas; complete coal ranks for coking with uneven distribution （large proportion of gas coal and 1/3 coking coal and low proportion of principal ranks of coking coal and fat coal）. At present, mining depth of coalmines in some larger coalfields in the North China coal accumulating region is extending to 800m with 15m per annum rate, several coalmines＇ mining depth are already as deep as 1000m, explored depth 1200m. Thus, to study coal metamorphism in deep part has profound significance. According to coal deep-seated metamorphism theory, the deep part coal quality of many coalfields in the eastern margin of North China coal accumulating region could be better and hosted large amount of fat coal, coking coal aod lean coal resources usually hard to get. If the predicted resuli is creditable, thus can hopefully eliminate the bottleneck of prime coking coal in short supply, and provide resource supports in the country＇s future economic development.
