摘　　要：为矿山开发和相似矿区找煤提供参考,分析了方山-白沙煤矿煤系地层特征,且利用标志层、层间距、煤岩层组合特征、煤层自身特征、测井曲线特征等方法对煤系地层进行了对比分析。研究表明,矿区煤系地层共划分为9个煤段,含煤25层,煤层总厚度11.92 m,发育全区可采煤层二1煤层和局部可采煤层七2煤层。To provide reference for mine development and coal prospecting in similar mining areas,the stratigraphic characteristics of the coal measures in Fangshan-baisha Coal Mine are analyzed,and the coal measures strata are compared and analyzed by using the methods of marker layer,layer spacing,combination characteristics of coal strata,characteristics of coal seams themselves,and characteristics of logging curves.The study shows that the coal measures strata in the mining area are divided into 9 coal sections,with 25 coal seams and a total thickness of 11.92 m.The whole minable the 21 coal seam and the local minable 72 coal seam are developed.
