Based on the thermal equilibrium equation of coal and oxygen reaction, a mathematical model of the shortest spontaneous combustion period of coal was put forward in order to forecast coal spontaneous combustion more accurately.

Study on spontaneous combustion period of coal based on activation energy index;

Based on the thermal equilibrium equation of coal and oxygen reaction, a mathematical model of the shortest spontaneous combustion period of coal was put forward in order to forecast coal spontaneous combustion more accurately.

Nowadays, there are many methods on studying spontaneous combustion period in our country, but because of many influence factors, there are a great differences between computed results and actual results on researching spontaneous combustion period.

Forecasting technique for spontaneous combustion stage on basis of L-MBP neural network;

Study on prediction model of coal spontaneous combustion stage;

Gray prediction model of spontaneous combustion stage of coal;

The paper determines coal spontaneous combustion characteristic parameters by means of simulating experiment of coal low temperature spontaneous combustion ,calculates coal natural fire time, critical temperature, gas producing rate , exothermicity and limit parameters.
