基于等间距网格法的瓦斯赋存主控因素分析

为了采用更准确的数据来研究煤层瓦斯的赋存规律,提出基于等间距网格法的瓦斯赋存规律的方法,该方法适用于多元数据分析。以某煤矿为例,通过对煤矿地质勘探钻孔资料、井田地质条件以及对所收集的数据进行分析处理,使用等间距网格法划分瓦斯数据单元,应用瓦斯地质理论和线性回归的方法,对煤矿二2煤层瓦斯赋存规律及其主控地质因素进行了研究。研究表明:煤层顶底板岩性和煤层厚度是影响该煤矿煤层瓦斯赋存的主要控制因素,其次是煤层上覆基岩厚度。

Study on the main controlling factors of gas occurrence based on equispaced grid method

In order to gain accurate data for studying the occurrence law of coal seam gas, a method has been proposed based on equidistant grid method, which is suitable for multivariate data analysis. The gas data unit is divided by the grid method of equal spacing after analyzing the borehole data of geological exploration, geological conditions of well field in a coal mine as example. Then, the gas occurrence regularities of No.2 seam and the main controlling geological factors are studied by applying gas geological theory and linear regression method. The research results show that the top floor rock and coal seam thickness are the main controlling factors of the gas occurrence in the coal seam, and the second is the thickness of bedrock overlying the coal seam.
