基于上覆基岩特征的赵固一矿井田煤层瓦斯富集区的判识方法
|
摘要
为了有效控制瓦斯矿井煤层瓦斯赋存的不均衡性,提出了煤矿煤层瓦斯富集区概念,给出了煤矿瓦斯富集区的一般特征,并基于赵固一矿井田具体地质条件,通过对其瓦斯地质特征的讨论,分析了厚黄土薄基岩煤层瓦斯富集区形成机理,确定了根据上覆基岩特征识别煤层瓦斯富集区的方法。以上覆基岩特征为判识标准,对赵固一矿井田煤层瓦斯富集区进行了初步的判识,井田煤层上覆基岩厚度>50 m且煤层上覆基岩梯度>0.06或煤层上覆基岩厚度>150 m的区域为煤层瓦斯富集区,井田内煤炭开采验证了煤层瓦斯富集区识别与实际瓦斯赋存的一致性。
In order to effectively control gas unbalance phenomenon of gas occurrence in coal mine,this paper put forward the concept of gas enrichment area and gave the general characteristics of gas enrichment area.Based on geological condition in Zhaogu No.1 Coal Mine,the paper discussed the gas geological features and analyzed the formation mechanism of gas enrichment area in the thick loess-thin bedrock coal seam,and then obtained the recognition method of gas enrichment area by the overlying bedrock characteristic of coal seam.On the basis of which,the gas enrichment area of Zhaogu No.1 Coal Mine was confirmed,that was the bedrock layer thickness greater than 50 m and coal seam overlying bedrock gradient greater than 0.06 or the bedrock layer thickness greater than 150 m area.Coal mining practice verified gas enrichment area identification and actual gas occurrence consistency.
