| 摘 要： | 通过引入实用缓冲算子来消除瓦斯涌出量原始数据序列所受到的冲击扰动以建立改进的灰色GM(1,1)预测模型,并利用MATLAB语言编程计算,选择合理的精度检验方法对预测模型和结果进行检验判断.通过实例验证了该模型对采面瓦斯涌出量的预测数据精度更高,可信度更好,可为煤矿企业有效排除矿井瓦斯涌出提供一定的决策依据.

| Abstract: | The improved grey model was derived by introducing the useful buffer operator to remove the impulsive perturbation to the original data sequence of gas gushing,and the MATLAB language was used to carry out model programmed calculating,then an appropriate accuracy inspection method was selected to test and judge the prediction model and the results.By proof of engineering projects,the gas gushing data predicted by using the model had higher accuracy and better credibility,which can provide coal mining enterp... |
