改进动量BP算法计算围岩风流不稳定传热系数

Improved Momentum BP Algorithm to Calculate Air Flow Unstable Heat Conducted Coefficient of Surrounding Rocks

针对围岩与风流之间不稳定传热系数Aτ的理论值解法的计算过程繁杂、容易出错等缺点,提出了基于改进动量BP算法的不稳定传热系数Aτ的预测计算模型,并以淄博矿业集团唐口煤矿的实测数据为例对网络进行了训练和学习,结果表明,该方法的使用可从多个方面改善网络的总体收敛性,具有较高的预测精度。

According to the complication, easy making mistake and other shortages of the theoretical value solution for the unstable heat conducted coefficient A, between surrounding rock and air flow, the paper provided the prediction calculation model of the unstable heat conducted coefficient AT based on the improved momentum BP algorithm. And taking the site measured data of Tangkou Mine, Zibo Coal Mining Group as an example, a training and learning of the network was conducted. The results showed the application of the method could improve general convergence of the network from many aspects, and could have high prediction accuracy.
