摘要
断裂—断块组合构成薛村井田基本构造轮廓,通过井下地质调查,研究了薛村井田地质构造发育特征及煤层断裂展布规律,结果表明:已采区中、小型煤层断层的展布具有分区性和方向性等特点,以NNE、NE向最为发育,NW向次之,倾角以55°～75°居多,且层滑断裂发育,对煤层破坏严重。
The Xuecun minefield is a minefield with extensional structures, through underground geological investigation discussed its geological structural development characteristics and coal seam fault distributing regulations. Demonstrated that the distributing of medium to minor coal seam faults have characteristics of zoning and directivity, i.e. NNE and NE are developed best of all, NW takes second place; dip angle is mostly 55°-75°, and interlayer-gliding faults are well developed, seriously disrupted coal seams.
