三维灰趋势面分析法在瓦斯涌出量预测中应用

Application of gas emission into mine by the methods of 3D grey trend surface analysis

生产现场表明:在一定的地质范围内,矿井瓦斯涌出量的变化是呈一种逐渐的趋势性变 化,而不是忽高忽低毫无规律变化的,因而可以用一个三维灰趋势面来描述其变化规律。本文介绍了灰趋势面分析法这种新的矿井瓦斯涌出量预测方法的建模机理和预测思路,并以湖南涟邵矿务局洪山殿矿蛇行山井四煤为例,进行了实际应用,在此基础上,绘制了井四煤层瓦斯涌出量分布的三维灰色趋势曲面,取得了优越于其他预测方法的结果。

it has been proved that the gas emission into the mines is a kind of trend of gradual changes instead of irregular changes in certain coalfield. It thus can be studied with a multiple mathematical model of trend surface analysis. In this thesis the author proposed a multiple mathematical model of trend surface analysis and found out a gas emission function which is applicable to She Xing Shan mine . some related data measured have been processed and graphed drawn by a computer. The author has found this method is better than other gas emission methods in prediction .
