Experimental Study on Performance that Ammonium Salt Retarder Inhibits Furong Coal Oxidation and Spontaneous Combustion
Adopting temperature programmed experiment, taking soft anthracite of Furong mine as experimental sample, the article conducts the temperature programmed experiment under atmosphere of different retarders. And then, by the comparison and analysis of spontaneous combustion characteristic parameters in the process of a temperature programmed run, the retarders inhibitory performance to different coal samples are analyzed. The results of experiment show that, at different temperatures of coal sample, NH4H2PO4, MgCl2 and NH4HCO3 have superior rate of retarder, and over 75％ of rate of retarder can be reached by 20％ of retarder inhibits. The result of experiment provides correlative reference for future development of efficient retarder inhibits in the work of coal mine fire prevention.
