Research on coal spontaneous combustion based on physical simulation

Coal spontaneous combustion is the main cause of mine fire and an urgent problem to be solved for the safe coal production. This paper describes the ordinary research method of coal mine fire, namely, the physical simulation, and points out that it is wrong to simply treat the research of coal mine fire as a temperature regulation problem. On the basic mathematical model of coal spontaneous combustion, this paper advances a view that this problem should mainly be attributed to a nonlinear and multi-variable control problem. Under this view, we have designed an experimental research equipment based on computer system and intelligent control algorithm, and applied it to research the coal mine fire.
