| 摘 要： | 通过对基于绝对误差最小的传统最小二乘法与在此基础上考虑相对误差的改进最小二乘法的比较,得知改进的最小二乘法预测更为准确。现场应用于鹤壁四矿的相对瓦斯涌出量随深度变化的预测,建立了瓦斯涌出量预测模型,通过预测值与实际值比较,证明改进的最小二乘法预测鹤壁四矿瓦斯涌出量是可行的、有效的,对指导煤矿安全生产具有重要意义。

| Abstract: | By comparing the traditional method of least squares that based on the minimum absolute error and the improved method of least squares considering the relative error ,it was found out that the improved forecasting results are more accu-rate .The improved model was used in the field of the prediction relative methane emission variation with depth in Hebi Mine 4 ,the gas emission prediction model was established and by comparison of the predicted value and actual value ,it was proved that it was feasible and effective to predict the gas emission of Hebi Mine 4 by use of the improved model of least square ,significant to guide the production of coal mine safety . |
