为了获得在煤柱留设研究中相对比较准确的预测公式,基于多元回归分析法,在总结全国各典型煤矿断层防隔水煤柱相关资料的基础上,以水头压力、煤层厚度、安全系数、煤体抗拉强度为主要影响因子,研究了煤矿断层防隔水煤柱的留设宽度预测,利用Matlab软件绘制散点图,并对其进行了多元线性回归和多元非线性回归分析,得到了煤柱留设宽度的非线性预测公式。通过煤矿实例对公式进行验证,并与经验公式比较,结果表明多元回归分析生成的预测模型具有较高的精确度。

In order to have a relative quite accurate prediction formula in the study on the coal pillar eft, based on the multiple regression analysis method and the summarization on the related information of each typical mine fault water prevention coal pillar in China, the water head pressure, seam thickness, safety coefficient an d coal tensile strength were applied as the primary influence factors to study the left width prediction of each mine fault water prevention coal pillar.The Matlab software was applied to prepare the scatter diagram and the multiple linear regression analysis and multiple nonlinear regression analysis were conducted.A nonlinear prediction formula of the coal pillar left width was obtained.Verification was conducted on the formula with the mine cases and the formula was compared with the empirical formul a.The results showed that the prediction model formed with the multiple regression analysis would have high accuracy and would have relative wide application prospec t
