摘要
利用开采区域、相邻采空区和回风巷间的气压差,在专用回风巷内控制释放采空区高位裂隙带瓦斯,同时在开采区域定时灌注CO2覆盖开采期间散落的溢煤,从而达到减少在采空区气压相对大时瓦斯向开采区域释放、采空区气压相对小时开采区域空气向采空区渗透,达到瓦斯与煤自燃共治的目的.
It is bad to utilize and exploit the area,adjoint atmospheric pressure that adopts the empty district and goes back among the wind lanes,in special-purpose to go back wind control release quarry empty district high-order crack take the gas in the lane,excessive coal falling scattered during exploiting the area and pouring into CO2 and covering and exploiting regularly at the same time,thus it reach reduce in quarrying districts empty atmospheric pressure gas when being the getting heavier relatively to exploiting there aren't area,achieve the goal that gas and coal spontaneous combustion manage together.
