灰色理论在预测深埋型矿井涌水量中的应用

Application of grey theory model in prediction of pit water discharge in coal mine

煤矿地下水动态的预测预报始终存在着计算过程复杂、计算量大、且难以兼顾影响矿井充水的各种因素、精度较低的特点;灰色系统理论则具有高度的概括性、简单的计算过程和极佳的预测精度,因此在工程界得到了广泛的应用。然而,用于矿井涌水量预测的不多,文章以灰色理论GM(1,1)模型为基础、在这方面进行了尝试,效果甚佳。

It,s very important to predicate pit water discharge in the work of prevention and cure of groundwater . The coventional predictive method are complex in the process of calculation , and can not take into account the influence of all factors on water discharge . Grey theory has a high summary , a simple calculation process and a good accuracy , therefore it is widely used in prediction of many engineering practices .But only a few are used to predict the pit water discharge in coal mine . This paper uses grey theory model in the prediction of pit water discharge in coal mine in Eighth Mine Pingdingshan, and obtained a good result.
