According to the gas observational data, the gas spatiotemporal distributionswere analyzed in full-mechanized top coal caving in thick, hard and high-gas seams. Thefactors influencing gas effusion were researched and the rules of gas effusion under thespecial conditions were educed, for example, the underground pressure, the output inten-sity, the working surface advancement, and the amount of ventilation in the working faceon gas effusion, and so on. The research results can be the base of forecasting gas effu-sion and controlling gas in these special conditions, which can guarantee the safety ofhighly efficient full-mechanized top coal caving.
