摘要
对综掘工作面瓦斯涌出来源进行了分析,依据质量守恒定理,对停风后掘进巷道瓦斯涌出规律进行理论计算,得出停风后巷道中瓦斯浓度分布规律。实测数据与理论计算结果进行比较,得出理论计算结果具有一定实用性。利用理论计算结果对停风巷道进行瓦斯浓度分析,从而为煤矿掘进巷道瓦斯排放提供理论参考。
The sources of gas emission were analyzed. According to the law of mass conser- vation, the law of gas emission at the working face after ceasing ventilation was theoretically cal- culated. Compared with the measured data, the theoretical calculation is of a certainpracticality. By using the theoretical calculation, the gas concentration in the roadway after ceasing ventilation was analyzed, providing a theoretical reference for the gas discharge.
