摘　　要：通过对煤自燃及其防治机理、无机磷化合物阻化机理及技术的现状研究,结合相关专业知识,分析了次亚磷酸钠、磷酸二氢钠、磷酸三钠和磷酸铝4种无机磷化合物对钱家营矿肥煤煤样的阻化规律。实验表明15%磷酸二氢钠对肥煤的阻化效果最好。从宏观的角度探究了无机磷化合物对煤自燃的阻化作用,对指示煤氧化自燃预防治理工作颇具实际性意义。Based on the research on spontaneous combustion of coal and mechanism of its prevention, the mechanism of resistance of inorganic phosphorus compounds and the status quo of technology, combined with the relevant professional knowledge,four kinds of inorganic phosphorus compounds such as sodium hypophosphite,sodium dihydrogen phosphate,trisodium phosphate and aluminum phosphate resistance of coal samples in Qianjiaying mine.Experiments show that 15%sodium dihydrogen phosphate has the best resistance to fat coal.From a macroscopic perspective,it explores the resistance of inorganic phosphorus compounds to the spontaneous combustion of coal,which has practical significance for the prevention and control of spontaneous combustion of coal.
