金沙县长兴煤矿可采煤层对比分析

Comparative Analysis of Recoverable Coal Seams in Changxing Coal Mine,Jinsha County

金沙县煤系地层以龙潭组为主,是一套海相和陆相交互沉积地层,且龙潭组为长兴煤矿主要含煤地层。为了提高对金沙县煤炭地质工作的认识,通过对金沙县长兴煤矿含煤地层的岩性特征、物性特征(测井曲线)、煤层层间距及煤层自身特征进行综合分析,认为长兴煤矿可采煤层(C4、C8和C12)比较可靠,可以作为今后对金沙县煤系地层开展地质工作的参考依据。

The coal-bearing strata in Jinsha County are mainly composed of Longtan Formation,which is a set of marine and continental interaction sedimentary strata,and the Longtan Formation is the main coal-bearing strata in Changxing Coal Mine.In order to improve the understanding of coal geological work in Jinsha County,through comprehensive analysis of lithologic characteristics,physical characteristics (logging curve),coal seam spacing and coal seam characteristics of coal-bearing strata in Changxing Coal Mine of Jinsha County,it is considered that coal can be mined in Changxing Coal Mine.The layers (C 4,C 8 and C 12 ) are more reliable and can be used as a reference for future geological work in the coal-bearing strata of Jinsha County.
