矿井煤层瓦斯赋存规律研究

Study on the Occurrence Law of Coal Seam Gas in Mines

瓦斯生于煤层,且储存于煤体中,煤体中瓦斯分布规律直接影响到煤层瓦斯灾害危险程度。特别是深部煤层及构造带煤层开采,瓦斯灾害越发严重。为实现矿井瓦斯治理工作的预见性和精准性,必须进行煤层瓦斯赋存规律的研究。以四川某煤矿为例,在煤层瓦斯参数测定基础上,分别通过地质构造、煤层开采标高及埋深等影响因素情况下,采取线性回归分析方法,研究分析了矿井瓦斯压力和瓦斯含量在地质构造带影响下赋存规律情况及分别与煤层标高和埋深之间的相关线性关系,为煤矿安全生产提供了保障。

Gas,originating from coal seams,is stored in coal deposits.The gas distribution law in coal deposits directly affects the risk level of coal seam gas disasters.Especially the mining of deep coal seams and structural belt coal seams faces increasingly serious gas disasters.In order to control mine gas predictably and accurately,it is necessary to study the occurrence law of coal seam gas.Taking a coal mine in Sichuan as an example,based on the measured coal seam gas parameters,linear regression analysis method was utilized to study and analyze the occurrence law of gas pressure and content under the influence of geological structure zones,as well as their linear relationship with coal seam elevation and depth,considering the influences of geological structures,coal seam mining elevation and depth,and providing a guarantee for safety production of coal mines.
