摘要
在野外地质和勘查资料分析的基础上,结合区域构造背景,论述了赵楼井田构造发育、组合及分布规律。研究表明:石炭—二叠纪成煤期后,多期性质、强度不同的构造作用相互叠加、改造,致使赵楼井田构造以断裂为主,褶皱发育次之。断裂构造主要有近NS、NW、NE及NNE向四组,其中以NE、NNE向为主,NW向断层组多为落差、延展长度都较小的断层。断裂以正断层为主,在剖面上主要表现为堑—垒构造组合,这种组合特征不仅使矿井构造更加复杂,而且使煤层的连续性受到破坏。井田东南部断层发育,断层叠加于早期的褶皱之上,破坏了褶皱的完整性,构成井田的构造复杂区。赵楼井田构造发育规律及成因机制的研究为今后矿井建设与生产提供了地质依据。
Based on the field geological and exploration data analyses, combined with regional tectonic setting, have discussed the structural development, combination and distribution pattern. The research results show that after the Permo-Carboniferous coalforming stage, mutual superimposition, reformation of multiple staged, different intensity tectogeneses have made the fractures proved to be the main structure form in the Zhaolou minefield, folds the second. The fault strikes include nearly NS, NW, NE and NNE, mainly NE and NNE. Most are normal faults; appear as graben-horst tectonic association on profiles, this association not only made mine structures complicated, but also destructed coal seam continuity. Faults well developed in southeastern part of the minefield, superimposed onto early-stage folds and destructed their integrity, made up the structurally complicated area. The research on structural development pattern and genetic mechanism provided mine construction and production with geological basis henceforth.
