通过对阿刀亥煤矿1203炮掘巷道的实测分析,找出了1203炮掘工作面煤壁和采落煤的瓦斯涌出规律,根据煤层赋存的一些基本参数和实测数据,建立了煤壁、落煤瓦斯涌出数学模型。并给出了炮掘落煤涌出高峰期的最大瓦斯浓度、煤壁瓦斯涌出枯竭极限时间、掘进巷道煤壁最大瓦斯涌出量以及掘进巷道煤壁达到最大瓦斯涌出量时巷道长度的计算方法。
According to the actual measurement and analysis of tunnel 1203 at Adaohai Coal Mine, the law of gas emission from the coal wall of 1203 coal mining face and the mining of coal was found out. According to some basic parameters and measured data of occurrence of coal seam, the coal wall , Fell coal gas emission mathematical model. The maximum gas concentration at the time when the coal is gushing out and the maximum time of gas emission and exhaustion of the coal wall are given, and the maximum gas emission from the coal wall of the driving roadway and the length of the tunnel when the coal wall of the driving roadway reaches the maximum gas emission Calculation method.
