摘    要：系统地综述了硫铁矿石氧化自燃的有关化学反应方程式,并用化学热力学的原理计算了有关反应过程的热效应,同时,应用试验方法确定了硫铁矿石在不同条件下的氧化过程所涉及的关键化学反应模式和反应速度及水的作用机理.该项研究结果对硫化矿矿井内火灾防治具有重要的指导作用.

Abstract: In this paper,some reacting equations for describing the oxidizing process of sulphideores are summarized systematically and their reacting heat has been calculated by the chemi-cal thermodynamics principle. The key reacting equations and velocities and the chemicalfunctions of water during the oxidizing process in different conditions have been determinedbased on the experimental method.The research results can be effectively used to guide thework for preventing and extinguishing the mine spontaneous combustion of sulphide ores.
