【摘要】 考虑到煤与瓦斯突出发生的内在机理的复杂性,突出影响因素与突出事件之间的非线性,阐述了人工神经网络的原理和算法,在分析了煤与瓦斯突出的主要影响因素的基础上,依据功能强大的matlab神经网络工具箱,采用BP人工神经网络模型,通过训练得到了影响突出因素与突出事件之间的关系,为突出非线性动力机制及预测提供了新的途径。实例表明,Matlab神经网络工具箱用于煤与瓦斯突出预测是可行的。更多还原

【Abstract】 Considering the arricle of the complexity of coal and gas outbursts and the non-linear between the factor of outburst and coal and gas outburst, introduces the principle and method of ANN.Making use of the function of neural network included in matlab and BP network model, the ralation between the outburst factor and outburst is obtained with the help of learning and training,providing a new approach for studying the non-linear dynamic mechanism and predication of coal gas outburst.The experimental results show that the artificial neural net is useful for forecasting the intensity of coal and gas outburst.更多还原
