Abstract:

The aim of the study is to find out gas composition and distribution characteristic and analyze geological controlling factors of high gas content in Huainan mining, which is vital to the development and comprehensive management of mining area gas. Research on the law of gas distribution in the Huainan mining area shows that, the CH4 content extend in N-W direction and NE higher than SW. CO2 content in this mining performances that south is higher north, while the N2 content shows a feature that south is lower than north. CO2 content is high in the turn end of PanJi anticline and low in the wings of anticline. N2 content is on the contrary. Main factors of controlling gas content in this mining are coal quality, buried depth, coal thickness, geological structure and groundwater activity. In addition, gas content were positively correlated with coal quality, buried depth and coal thickness. Sealing fracture structure is beneficial to gas accumulation, while the open fracture structure will reduce gas content. Gas content decreases with the lithologic particle coarsening. Retention groundwater will make for methane’s accumulation.
