摘　　要：在对井下不同结构煤体变形及分布特征观测分析的基础上,结合其在测井曲线上的响应特征,对新景煤矿3号煤层不同煤体结构进行了判识和划分。结果表明,新景煤矿3号煤层煤体结构以Ⅰ类煤和Ⅱ类煤为主,Ⅲ类煤局部发育。煤体结构破坏程度严重的煤主要分布在不同期次构造叠加区域以及背、向斜的轴部,小断层附近也可见到;煤体结构破坏程度弱的煤主要分布在煤层产状平缓以及褶曲翼部地区。Based on observation and analysis of deformation and distribution of different coal structure, combined with different response characteristics of different coal structure on logs, this paper identifies and divides different coal structures of seam No.3 in Xinjing Mine. The results show that structures of seam No.3 are primarily of coal of classⅠand classⅡ, and locally coal of classⅢ develops. The coal structure which has been seriously destroyed mostly develops in the superposition area of tectonic movements of different periods, axis of anticline and syncline, small faults also can be seen in the vicinity. Coal structures suffering minor damage are mainly located in the area with seams of gentle ocurrence and wings of folds.
