SPSS软件在抽放半径影响因素分析中的应用

Application on SPSS Software in Drainage Radius Effect Factors Analysis

在分析中泰矿业4505、31021等7个工作面抽放半径变化情况的基础上,选取瓦斯原始含量、煤层透气性、瓦斯释放初速度、瓦斯原始压力、煤层坚固性系数、孔隙率和煤层厚度等7个对抽放半径有较显著影响的因子,运用SPSS软件对这些影响因素进行多元线性回归分析,可以得到适用于本煤层的抽放半径与其影响因素之间的关系式。

This paper is based on the analysis of the changes of the drainage radius about seven working faces as 4505, 31021 and etc. in Zhongtai mining, choose the seven significant influence factors to drainage radius such as the gas original content, coal seam permeability, gas release initial speed, the original gas pressure, coal seam rigidity coefficient, porosity and the thickness of coal seam, using the SPSS software for these influence factors carries out the multivariate linear regression analysis, can get the relation that is suitable for the coal seam drainage radius and its influence factors.
