禹州梁北一号井田构造特征及成因分析

利用井田勘探资料及野外地质资料,分析了梁北一号井田构造特征,认为该井田以断层为主,具有镶嵌构造特征,井田的构造格局是多期构造运动综合作用、互相叠加的结果,喜马拉雅运动对井田构造格架的形成具有重要影响。井田内断层发育,与煤层赋存和开采有密切关系,一方面断层的发育破坏了煤层的连续性和完整性,给煤岩开采造成很大困难;另一方面断层的发育使得埋藏较深的煤层向上抬升,埋藏变浅,有利于开采,扩大了煤层开采的有效面积。

Liangbei No.1 Minefield Structural Characteristics and Their Genesis Analysis

Based on minefield exploration and field geological data, analyzed Liangbei No.l minefield structural characteristics, considered that minefield structure is mainly faults, mosaic structure is the main feature. Tectonic framework is a result of multiphase tectonic integrated activities reciprocal staking, the Himalayan orogeny has major impact on the formation of the tectonic framework. The development of faults in the minefield has close relation with coal seam hosting and mining. On the one hand, the development of fault destructed coal seam continuity and integrity, puzzling coal mining; on the other hand, faults uplifted deep buried coal seams in favor of mining, extending coal seam effective mining area and formed large-sized minefield.
