为了提高矿井涌水量预测的精度,基于多元回归分析法,以可能影响涌水量的累计采空面积、累计煤炭产量、累计采掘进尺、采厚为主要影响因子,对涌水量进行预测研究。利用SPSS软件分析相关程度、Matlab软件绘制散点图,并对其进行了多元非线性回归分析,得到了矿井涌水量的非线性预测公式。通过矿井实例进行验证,结果表明使用多元回归分析法对矿井涌水量的预测具有较高的精确度。
In order to improve the prediction accuracy of mine water inflow, based on multivariate regression analysis, the cumulative gob area, cumulative coal production, accumulated footage and mining thickness as the main factors that may influence the water inflow were used to forecast the influx. Using SPSS software to analyze the correlation degree, the Matlab software draws the scatter plot, and carries on the multivariate nonlinear regression analysis to it, obtains the non-linear prediction formula of mine water inflow. Through the example of mine, the results show that the multivariate regression analysis method has a higher accuracy in prediction of mine water inflow.
