铜川矿区鸭口矿瓦斯赋存规律研究

Reasearch on Gas Occurrence Law of Yakou Coal Mine in Tongchuan Mining Area

鸭口煤矿位于铜川矿区东南部,主采5-2煤煤,针对该矿具体情况,运用相关性分析、灰色关联分析等方法,对影响瓦斯含量的地质因素进行分析。结果表明,瓦斯含量主控因素为上覆地层有效厚度,其他因素会对瓦斯局部分布产生影响。分析认为,瓦斯含量中部和南部较低,西北部和东北部较高。西北部自东向西由0.5m3/t逐渐增加至2.0m3/t,东北部由南西向北东由0.5m3/t逐渐增加至1.0m3/t。

Yakou Coal Mine locates in southeast of Tongchuan mining area,and the main mining coal seam is 52 coal seam,aiming at the status quo of the coal mine,geological factors influencing gas content were analysed by using relative analysis and gray correlation a nalysis etc. Results show that,the main controlling factor is the overlying rock＇s effective thickness, and other factors can influence gas content in some regions. It was shown that the gas content in middle and southern regions is low, and is high in northwest and northeast regions. In northwest region,the gas content gradually increased from O. 5 m3/t in east to 2.0 m3/t in west. In northeast region,the gas content increased from 0.5 m3/t in southwest to 1.0 m/t in northeast.
