以预测未采工作面的涌水量为目的首次将涌水量预测中具有时间特征的灰色理论GM(1,1)模型和具有空间特征的水文地质比拟法有机结合起来,提出一种具有时间空间特征的计算方法——GM(1,1)-水文地质比拟法,并对未采工作面进行涌水量预测,预测结果为1 371.4m3/h。采用解析法预测的该工作面涌水量值为1 369 m3/h,二者相对误差为0.175%。所提出的计算方法能够用于未采工作面的涌水量预测,为未采工作面设计临时水仓的大小以及确定排水能力提供一种新方法。
For the first time, for the purpose of predicting the inflow of unworked working face, the gray theory GM (1,1) model with temporal characteristics in the prediction of inflow water volume and the hydrogeological comparison method with spatial features were firstly combined organically to provide a time-space feature The calculation method of GW (1,1) - hydrogeology is used to predict the water inflow of the unworked working face. The predicted result is 1 371.4m3 / h. The water inflow value of the working face predicted by analytic method is 1 369 m3 / h, the relative error between them is 0.175%. The proposed method can be used to predict the influx of water in a non-working face, to provide a new method for designing the size of a temporary tank and the ability to determine the drainage capacity of a non-working face.
