摘要
运用灰色模型得出了回采工作面和掘进工作面的瓦斯涌出量预测值;统计分析了7601综采工作面日产量(日进度)与相对瓦斯涌出量之间的关系;运用MATLAB曲线拟合工具,通过对原始数据的等间隔序列化等处理,得到了灰色预测模型。实测检验表明该方法预测结果与实际基本吻合。
Gas emission of working face and heading face is predicted by grey model prediction. The relationship between daily output and the relative gas emission is analysed by statistic data from 7601 working face. By using MATIJtB curve fitting tool and interval a grey model is got. The results show that all these methods are in accordance with practical case.
