Application On Optimum Inhibitor For Preventing The Spontaneous Combustion Of Coal In Gob Of Tianchi Of Yanzhou Coal Mining Group

In this article, aimed at mined-out area of Tianchi of Yanzhou Coal Mining Group fire prevention and control optimization of inhibitor.Select activation energy as a kind of spontaneous combustion tendency of coal identification of indicators. Inhibitor studies of the mechanism of resistance, resistance-oriented features, a different inhibitor resistance variation of characteristics and selection of suitable coal sample inhibitor.In this article, select the 102 and 103, Lane 106 # frame coal sample surface, using STA449C TGA experiments on coal samples, using origin software data linear fitting, using the calculation method of thermal analysis kinetics obtained the response phase of the activation energy.Conclude: The oxidation of coal combustion process can be divided into stages of dehydration weight loss, weight gain phase of oxidation and combustion of the three stages of weight loss phase. The different stages of coal oxidation reaction of the reaction activation energy in accordance with the order, followed by larger, indicating reaction from easy to difficult general law. Inhibitor added after the dehydration phase of ignition of coal samples have increased the activation energy, indicating a very good inhibitor of the inhibitor effect. Comparison of coal sample after adding different inhibitor activation energy changes of the coal sample was found on the inhibitor is a selective, and only choose the appropriate inhibitor in order to achieve the desired effect of blocking technology.
