安徽芦岭煤矿Ⅱ88采区瓦斯地质规律
Gas-geology principle of Ⅱ 88 mining area in the Luling coal mine, Anhui, China
摘要
Abstract
According to structure geology, sequence stratigraphy, gas pressure, gas content, gas emission and other factors, this paper analyzes the gas-geology principle in II 88 mining area in the Luling coal mine of Suzhou in Anhui, and establishes the kinematic model and the pressure gradient calculation model. The Luling coal mine is controlled by the Xusu arc structure and duplex thrust that make the stress more concentrated, the gas pressure and gas content bigger, and the outburst disaster risk more serious than other mines in the Sulin mine area. In sequence, the 8th coal seam is the thickest stable coal seam developed near the maximum flooding surface, so the trap effectiveness of its roof and floor is good and the coal gas is accumulated. Faults superposition regions are prone to coal and gas outburst. II 88 mining area is divided into the east and west gas geological units which have a different gas pressure gradient, respectively. The gas pressure in the east gas geology unit of higher elevation is the bigger, because the coal roofs of the hanging wall were damaged during the stretch of F14 normal fault. The research achievement is not only of essential guiding significance to the safety production of II 88 mining area, but also provides a reference for the study on the coal gas geology principle of other mines.关键词
