Danger Of Spontaneous Combustion Coal Combustion Prediction Method

Risk of spontaneous combustion in coal seam coal forecast is an important guarantee to achieve safety, it provides spontaneous combustion of coal left the law and the early prediction, real-time prediction methodologies. Analysis can even ignite spontaneously coal seams intermixed the 7 mines of sanhejian coal even ignite spontaneously and angry, for seven coal risks to predict. her temper even ignite spontaneously. Via a thermal analysis of the experiment, temperatures of the analysis of coal, the oxygen and hot and cold of the summary of coal regularly. By citing coal seams intermixed even ignite spontaneously his prediction models to forecast of coal, down the temperature change the laws. even ignite spontaneously. Through mapping to gather in the area to gather the oxygen level of coal, coal product and the analysis of the actual temperature changes to its laws, and the function. Finally to adopt a model, the temperature of gob,then combination of data mapping empty area to gather the temperature field simulation. Simulated empty area to gather information. the temperature change. These prediction methods, application and realization of the smooth face for the 7137 coal mining and with the close, similar to face firing spontaneous combustion risk provides an important basis for prediction. Coal Seam for other risk prediction of spontaneous combustion also provide a reference.Figure [29] table [25] reference [58]...
