芦岭煤矿8、10煤层煤体结构成因探讨

Study on Genesis of Coal Structure of No.8&10 Coal Seams in Luling Mining

通过解译芦岭煤矿8、10煤层钻孔测井曲线和井下观察,描述了8、10煤层煤体结构特征;从褶皱、断层、层滑构造和煤岩成分的角度,探讨了它们对煤体结构成因的影响。研究结果表明在构造复杂块段煤体结构破碎严重,8煤层的破碎程度比10煤层严重。

The character of No. 8＆10 coal seams was described by explaining the drilling logging curve and observation in underground, from the perspectives of fault, fold, layer slip structure and Petrography Composition, the cause of coal structure was studied. The results show that coal structure was seriously crushing in complex area, the degree of damage of No. 8 coal more serious than No. 10 coal.
