贵州习水矿区构造特征分析

Discussion on Structural Characteristics in Xishui Mining Area

根据已有煤田地质资料,对习水矿区的地质构造进行了分析研究,认为矿区断裂以正断层为主,断层力学性质多属压扭性,东西向构造早于北东向构造;构造复合部位较复杂,其余区段较简单;矿区南部以褶断带为主,北部以断裂为主的单斜构造带。构造线方向性明显,与区域构造线方向一致。建议在矿区开发时,应尽可能避开构造复合部位(区段),选择构造对煤层影响较小的矿区北部地段。

Based on geological data of look for coal,the paper analyzed geological structure in the Xishui mining area,considered that the faulted structure in the mining area is mainly compresso-sheafing normal faults. EW structure is earlier than NE structure, structural compounding part is rather complex, while other parts are simple. Southern mining area is mainly a fault-fold zone; northern part is mainly faulted monocline zone, Directivity of structural line is clear; it is in accord with tectonic lineament. It is advised that during the mining area exploitation, the structural compounding part should keep away from; while the northern part of the mining area less structural impact sector will be better.
