采用遥感图像解译、天然地震震源分析等手段,对邯郸-峰峰矿区的新生代构造特征进行了深入研究.受太行山山前断裂带伸展滑脱的区域构造背景条件的控制,邯郸-峰峰矿区的先存断裂在新生代不同程度地重新活动,同时形成一些新断裂.矿区新构造格架由NNE-SSW向构造线与NWW-SEE向构造线组合而成,两组断裂交汇部位是底板突水、瓦斯突出等矿井地质灾害的易发地段.在华北新生代伸展变形区,新构造,尤其是活动断裂对矿井安全生产的影响应引起充分的重视.
Using the interpretation of remote sensing images and the source analysis of natural earthquakes, the Cenozoic tectonic characteristics of Handan-Fengfeng mining area have been deeply studied.According to the tectonic setting of the tectonic setting of the extensional slip of the Taihangshan piedmont fault zone, the Handan-Fengfeng mining area Of the pre-existing faults re-activated to varying extents in the Cenozoic and formed some new faults at the same time.The new tectonic framework of the mining area is composed of a combination of NNE-SSW tectonic line and NWW-SEE tectonic line, Water and gas outburst, etc. In the Cenozoic extensional deformation zone of North China, the attention of new tectonics, especially active fractures, should affect mine safety.
