There are fault thrust,strike slip fault and over thrust in this thrust nappe.
推覆体主要为震旦系、寒武系的灰岩,由NW→SE推覆掩盖在志留系页岩之上,主滑脱面倾角较小(10°～20°)。
The Cambrian Fengtai Formation under thrust nappes and the Carboniferous system of North Huaiyang Formation,which are both marine deposits,are the main gas source rocks of tunnel combustible gas.
在大别造山带内发现的可燃天然气和发生燃烧的隧道具有明显的区域性,集中分布于磨子潭-晓天断裂以南的北大别杂岩带和信阳-舒城断裂附近的早石炭世变质石英片岩中,磨子潭-晓天断裂和信阳-舒城断裂是连通深部气源的通道断裂;推覆体之下的寒武系凤台组和北淮阳型石炭系两套海相烃源岩是隧道可燃天然气的主力气源岩,其中下寒武统凤台组烃源岩具有高碳、高"Ro"、高Tmax、低氯仿"A"的特点,已进入热演化的过成熟阶段;北淮阳型石炭系烃源岩有机质丰度高,以Ⅲ型干酪根为主,热演化程度很高,大量的油气已经生成,最重要的是研究其成烃过程与圈闭配套史的关系。
The Lower Cambrian Fengtai Formation below thrust nappes and the North Huaiyang Carboniferous strata,both of which occur as the marine source rocks,are considered as the main gas source rocks of the tunnel combustible gas.
在大别造山带内发现的可燃天然气和发生燃烧的隧道具有明显的区域性,集中分布于磨子潭-晓天断裂以南的北大别杂岩带和信阳-舒城断裂附近的早石炭世变质石英片岩中,磨子潭-晓天断裂和信阳-舒城断裂是连通深部的气源通道断裂;推覆体之下的下寒武统凤台组和北淮阳型石炭系两套海相烃源岩是隧道可燃天然气的主力气源岩,其中下寒武统凤台组属大陆边缘沉积,其发育的海相泥质烃源岩具有高碳,高"Ro",高Tm ax和低氯仿"A"的特点,已进入热演化的过成熟阶段;北淮阳型石炭系处于前陆盆地的沉积中心,地层序列齐全,其煤系源岩有机质丰度高,以Ⅲ型干酪根为主,热演化程度很高,大量的油气已经生成,最重要的是研究其成烃过程与圈闭配套史的关系。

The nappe lane in the east-south coaling face has too much water locally which will threaten the safe coaling of 150801 face that is the first one under the board of the nappe lane in Xinji Mine.
150801面是新集矿区推覆体夹片下开采的第一个工作面,由于南东翼采区推覆体夹片局部富水,推覆体夹片水将威胁150801面的安全回采;通过对推覆体夹片水文地质条件的进行分析,并对150801面安全开采的可行性进行了论证,提出了150801面推覆体夹片下留设48 m防水煤柱开采可行性;通过开采实践证明:150801面推覆体夹片下防水煤柱48 m的开采是可行的,为矿区相似条件下全面提高回采上限提供了技术依据。
