摘要
运用瓦斯地质理论,以平顶山矿区八矿为研究对象,基于地质构造对区域、矿区和井田瓦斯赋存的控制特征,研究了三级构造对平顶山八矿突出煤层瓦斯赋存的地质构造逐级控制特征.研究表明:区域构造奠定了平顶山矿区高瓦斯的基调;矿区构造将平顶山矿区划分为东西2个瓦斯赋存单元,瓦斯赋存以李口向斜呈轴对称分布;井田构造控制着矿井突出煤层的瓦斯赋存和构造煤分布,造成煤层瓦斯突出危险呈条带分布,合理划分出煤与瓦斯突出发生有利地带.
Abstract
Using the theory of gas geology, at No.8 Mine in Pingdingshan mine area, based on the control characteristics of geological structure on the regional area, mining area and mine gas occurrence, authors studied the control characteristics of a three-level structure on outbursts coal seam gas occurrence characteristics in Pingdingshan No.8 Mine.Research results show that the regional structure establishes the fundamental key of high gas in Pingdingshan mine area.The mining area is divided into two gas occurrence units by geological structure, and the gas occurrence is axially symmetric distributed around Likou syncline.The structure controls the outbursts coal seam gas occurrence and the distribution of structural coal in the coalfield, which causes the banding distribution of coal seam with coal and gas outbursts hazard.Based on the study, the coal and gas outburst favorable zone is reasonably divided.
