Abstract:

In order to forecast coal spontaneous combustion, take advantage of BP neural network. The date is recorded from one coal mine of Donghuantuo. The input of the neural network is the concentration of CO, CO2 and CH4 in different temperature and use CH4-to-CO, O2-to-CO2 ratio. In this way, the influence of the wind will be little. After trained, the network can show 0 or 1 which represent fire or not. After trained 43 times, the error is lower than 0.000 1. It proves that BP neural network can deal with the date of coal mine. What’s more, BP neural network has huge advantages.
