选模型预测矿井瓦斯涌出量

he paper applies the selecting model into the selection of elements which affect the gas emission in the coal mine. With adjusted R-Square as the standard of judging the fitting equation, it uses the SAS to program and obtains the optimal subset, and then uses Excel to process data and reaches the curve fitting equation. Finally, after calculating the predicted values and the true values, it comes to the conclusion that: by establishing regression model, the method can simplify the model, reduce the involvement of superfluous independent variables in regression calculation and help improve the fitting accuracy, thus it could be better for forecasting and controlling the gas emission in the coal mine.
