摘要
本文从大佛寺煤矿40106工作面运输顺槽瓦斯涌出的特征和浓度分布入手,基于机掘巷道瓦斯涌出量是一个含多因素的复变函数,利用巷道测定法对40106运输巷掘进工作面煤壁的瓦斯涌出强度进行了实测研究,建立掘进工作面煤壁对瓦斯涌出量影响的数学模型为,得出了当巷道暴露时间为3～4个月时,掘进长度达900～1200m时,巷道瓦斯涌出量达到最大值,巷道长度再时,瓦斯涌出量基本趋于稳定值。
The paper starting with the gas gushing＇s characteristics and concentration distribution in 40106 working face crossheading in Dafosi Mine. Because the gas gushing in machine driven headings is a complex function with multivariate,use the laneway-mensu-ration in 40106 working face crossheading to get a mathematical model which reveal the relationship between coal wall heading face and gas emission.The conclusion is when the laneway＇s exposure time reached three to four monthes,the tunneling length reached 900-1200 meters,the laneway＇s gas emission reached the maximum.If the laneway＇s length increased more,the gas emission becomes a fixed value.
