Spontaneous combustion of coal based on fuzzy classification

Mine fire, in particular, incidents of spontaneous combustion of coal mine production safety hazards in the sense that no less than gas and coal dust explosion. Spontaneous combustion of coal, compared with the external fire has occurred, and regularly promoting the development of slow process of evolution can be found in the early stages of its formation. In this paper, fuzzy comprehensive evaluation method established evaluation model of spontaneous combustion of coal, and from the spontaneous combustion tendency of coal there was crushing accumulation of states, is proper ventilation and oxygen supply, a good heat storage environment, to maintain the continuous development of coal oxidation time of 4 factors to evaluate the level of well-off spontaneous combustion of coal mines. Evaluation model of spontaneous combustion control of coal mine has important reference value.
