摘要
为了研究控制煤层厚度的影响因素,以安徽省淮南市潘集煤矿外围的钻孔数据为基础,分别提取了该地区主采8#煤层的6个变量。通过对应分析的方法,利用Matlab软件编程计算出R型和Q型因子载荷,并作出因子载荷图,将变量与样品直观地展现在一张图上。观察因子载荷图与因子载荷表,分别分析变量之间、样本之间以及变量与样本之间的关系,从而找出控制煤层厚度的影响因素。分析结果表明:潘集煤矿外围煤层厚度的主要控制因素是古地形、现在构造以及岩相古地理的水动力条件。
In order to study the control factors of coal seam thickness,based on the peripheral drilling data of Panji Coal Mine in Huainan of Anhui,six variables of No.8 coal seam,the main coal seam in the area,were extracted.Through the method of correspondence analysis,Matlab software was used to program and calculate the R-type and Q-type factor load and make a factor loading graph,which showed the variables and samples intuitively on a graph.Through analyzing the relationship among the different variables,among the different samples,and between the variable and the sample,the control influence factors of the coal seam thickness were found.The results showed that the main factors that controlling the thickness of coal seam around the Panji Coal Mine were ancient topography,present tectonic and hydrodynamic conditions of the paleogeography.
