摘要
冀北地区的兴隆煤田由于受区域构造影响,形成了较为独特的逆冲推覆构造,地质条件十分复杂。在逆冲推覆构造的影响下,兴隆煤田各井田形成典型的叠瓦式构造,逆断层广布,深部煤层推覆至地表形成浅部煤层和露头,岩浆岩沿断层侵入煤层,逆冲推覆构造不利于深部煤层瓦斯发散,却利于浅部区域瓦斯溢出,形成了对瓦斯地质独特的影响。
Xinglong coalfield in northern Hebei region formed a relatively unique recoil and overburden structure due to the influence of regional tectonics,and the geological conditions were very complex.Under the influence of the reverse thrust structure,Xinglong coalfield formed a typical stacked tile structure with extensive reverse faults,deep coal seams thrust to the surface to form shallow coal seams and outcrops,magmatic rocks intrude into coal seams by extending the faults,the reverse thrust structure was not conducive to gas dispersion in deep coal seams,but is conducive to gas overflow in shallow areas,forming a unique impact on gas geology.
