This thesis presents the new concept of "high-temperature stope" in high-sulphur mines,explains by the principle of heat mechanics that it is formed due to the accumulation of large quantities of heat generated by the oxidation and spontaneous combustion of high-sulphur ore,analyzes main harms of high-temperature stope such as causing sulphur-dust explosion,instable surrounding rock and environmental pollution,and finally expounds the main measures of prevention and treatment against high-temperature stope such as good ventilation,timely ore drawing,appropriate ore size and grouted cable supporting.
