| 摘 要： | 为了进一步研究炮掘巷道煤壁瓦斯涌出规律,确定合理通风设计和制定瓦斯防治措施.通过测定煤壁瓦斯涌出强度并建立经验公式,研究煤壁瓦斯涌出与巷道长度、暴露时间的关系.结果表明,炮掘巷道煤壁瓦斯涌出强度随时间的变化符合双曲线关系,并得出了煤壁瓦斯涌出的极限巷道长度;还根据瓦斯的不同来源和含量,将掘进工作面风流流动分为3个区段,分别为折返区、风流不稳定区和风流稳定区.

| Abstract: | In order to further research on the gas emission law of coal wall in the blasting driving gateway, the paper nationally defined the ventilation design and set up the gas prevention and control measures. With the measurements of the gas emission intensity of the coal wall and the establishment of the experience formula, the paper researched the relationship between the coal wall gas emission and the gateway length, the exposed time. The results showed that the gas emission intensity of the coal wall in the b... |
