A sum total of 29 chemical reaction equations for describing the oxidizing behaviour of major sulphide oreswere summarized systematically and their reaction heat was calculated in detail according to the chemical thermody-namic principle.Furthermore,the key equations of them,reaction velocity and other relevant features in various conditions were determined based On the experiment analysis.Meanwhile,a large scale field experiment was made in a mine by piling volumes of sulphide ore dumps in a stope and continuously measuring their temperature,SO2 concentrations and environmental conditions during spontaneous combustion.The most practical and complete chemical thermodynamic behaviour and features were discovered in the experiment.These discoveries are identical with those achieved in laboratory.The research conclusions are of great significance for the control of mine sponta-neous combustion of sulphide ores.
