煤与瓦斯突出是严重危害煤矿安全生产的一种非线性瓦斯动力灾害。文章将BP神经网络运用于煤与瓦斯突出预测模型,从煤与瓦斯突出的原因、BP神经网络用于煤与瓦斯突出预测的原理、运用实例三方面,对利用BP神经网络预测煤与瓦斯突出的研究加以阐释,证明了BP神经网路预测系统的精度高于传统系统。 Coal and gas outburst is a kind of non-linear gas dynamic disaster that seriously endangers coal mine safety production. This paper applies BP neural network to prediction model of coal and gas outburst. Based on the reason of coal and gas outburst, the theory of BP neural network used in coal and gas outburst prediction, and the application of BP neural network to forecast the coal and gas outburst The study proves that the accuracy of BP neural network prediction system is higher than that of traditional system.
