以唐山矿西南区勘探与瓦斯地质资料为基础,对唐山矿西南区煤层瓦斯地质特征进行研究,并基于多元线性回归对未采区5、8、9煤层瓦斯涌出量进行预测。结果表明:9煤层瓦斯涌出量整体较大,绝大部分区域涌出量大于8 m3/min,最大可达23.6 m3/min;5煤绝对瓦斯涌出量最大可达6 m3/min以上,中部绝对瓦斯涌出量相对较低,瓦斯涌出量差异较大;8煤瓦斯涌出量主要约介于1.5~4.5 m3/min,整体小于5煤,预测结果与已采区瓦斯涌出规律一致。
Based on the exploration and gas geological data of southwestern area of Tangshan Mine, the gas geological characteristics of coal seam in southwestern Tangshan mine are studied. The gas emission of coal seams 5, 8 and 9 in non-mining area is predicted based on multiple linear regression. The results show that the gas emission amount of No.9 coal seam is large as a whole, the emission rate in most areas is more than 8 m3 / min and the maximum can reach 23.6 m3 / min; the absolute gas emission of 5 coal can reach 6 m3 / min or more, The absolute gas emission in the middle part is relatively low, and the difference in gas emission is quite large. The gas emission of 8 coal is mainly between 1.5 and 4.5 m3 / min, less than 5% in total, and the prediction result is consistent with the law of gas emission Consistent.
