贵州盘北-水城地区煤资源特性及其意义

Characteristics of coal resources and its significance in northern Panjiang and Shuicheng mining district,Guizhou

盘北-水城矿区上二叠统龙潭组和汪家寨组煤资源具有高镜质组、中高硫、中高灰、中低挥发分、高灰熔性和相对富氢(相对于相同煤级)的特性,其煤岩组成、硫含量、灰分等主要受聚煤期三角洲-滨岸沉积体系控制,煤的挥发分产率、碳氢比等主要受到煤变质作用的影响。区内化工煤资源丰富(主要为焦化煤和气化煤),焦化煤资源丰富且集中,而液化煤稀少但相对集中。建议在盘北-水城矿区规划3个煤化工基地:水城煤焦化基地、水城煤直接液化基地、盘北煤焦化基地。

Upper Permian Longtan Formation and Wangjiazhai Formation coals＇ resources characteristics and their variation law are summarized through sampled - test alaysis and statistics in northern Panjiang and Shuicheng mining district. The results show that the coal characteristics is of high vitrinite content, medium-high-sulphur, medium-high-ash, high ash melting point, relative richhydrogen（comparing with the same coal rank） in this area, which is closely related to geologic setting and geologic control, the lithotypes, sulfur content and ash content is mainly controlled by delta-onshore depositional system, the volatile matter content and carbon hydrogen ratio is mainly effected by coal metamorphism; The district is rich in chemical coal resources, the gasified coal and coking coal reserves are the primary types of the chemical coal resources ; The coking coal reserves are concentrated and abundant, the liquefaction coal is rare but relatively concentrated. It is feasible to establish Shuicheng direct coal liquefaction base, Shuicheng coal coking base and North Panjiang coal coking base in the area.
