摘要

江西省煤炭资源相对集中,以萍乐坳陷带煤炭资源较为丰富,主要为龙潭组B4煤层,煤层厚度较大且分布较为稳定,平均厚度达3 m,区内煤层的煤质特征、构造特征、水文地质条件、埋深以及顶底板特征为煤层气聚集提供了有利的生储盖条件。综合分析,江西省萍乐坳陷带煤层具有煤层气聚集条件,煤层气资源前景良好。
        Based on the data collection and analysis of major coal-bearing strata of Pingle Depression in Jiangxi province, coal resources in Jiangxi province are relatively concentrated, and coal resources of Pingle depression are abundant. Average thickness up to 3 m, Longtan formation B4 coal seam is the major coal-bearing strata, the coal seam is thicker and the distribution is stable.The coal quality characteristics, structural characteristics, hydrogeological conditions, buried depth, roof and floor characteristics provide favorable conditions for the storage and cover of coalbed methane. According to the comprehensive analysis, the coal seams in the Pingle depression of Jiangxi Province have coalbed methane accumulation conditions, and the prospects of coalbed methane resources are good.
