Study on the Application of Improved BP Neural Network in Forecasting the Types of Support of Development Roadways

In this paper, based on investigating and analyzing on the affecting factors for support type of development roadways as well as the successful support cases in Chengchao Iron mine, the improved BP neural network is put forward to study on the support type of development roadways. It may be seen from the learning course of learning samples and the prediction results of support types that whether the astringency of learning samples or the prediction results of support types show the high quality and efficiency. It provides a new thought to study on support types of development roadways and has high popularization value. And the limitation and further research goal are also pointed out in this paper.
