Abstract


Aiming at the 2322 (3) fully mechanized top-coal caving face of Panyi coal mine, the paper introduced the geological situation and spontaneous combustion situation and established the detection system of the top coal temperature along the upper level in order to forecast the spontaneous combustion situation. The author collected coal samples and experimented with DSC-TG thermal analysis and measured the thermal conductivity index. Through analyzing the environment condition of spontaneous combustion and ventilation leakage and oxygen distribution on the top coal temperature along the upper level, using the solution to the limit index of spontaneous combustion and basing on the results measued in the laboratory and current field, the author analyzed the decision condition in dangerous area of spontaneous combustion, researched the spontaneous combustion rules on the 2322 (3) fully mechanized top-coal caving face of Panyi coal mine and built the mathematical model of spontaneous combustion. Based on the conclusion and method of the research above, it is convenient to forecast the spontaneous combustion situation along the upper level, detect the fire of spontaneous combustion timely and make proper rules and regulations of fire extinguishing and prevention.
