چکیده
A simplified model for SO2 generation during spontaneous combustion of coal gangue was put forward and validated using the measured data. Using proposed model, effects initial temperature inside fresh air supply on were discussed. The results showed that, higher could accelerate oxidation rate FeS2 increase maximum concentration SO2. If increased by about 37%, total 166%. Fresh had less significant effect FeS2. However, was, more be oxidized, which ultimately produced Although computed data concerning inner locations a certain degree error, can provide relatively precise release within acceptable accuracy. Besides, this method provides useful prototype to predict hazardous materials, such as CO, NOx, chlorine gangue.

Control System of Spontaneous Combustion in Coal Gangue Dumps – a Case Study at Yuquan Coal Mine in China
Preliminary communication Spontaneous combustion in coal gangue dumps leads to pollution in the environment and damages ecosystem and human health. Mine operators usually fail to take effective measures against spontaneous combustion because of the inaccurate detection of the location of spontaneous combustion bursts. To address this issue, a control system of spontaneous combustion in coal gan...
متن کاملModelling Spontaneous Combustion of Coal
Spontaneous combustion of coal is an important problem in mining and storage, in terms of both safety and economics. This is because coal reacts with oxygen in the air and an exothermic reaction occurs, even in ambient conditions. The heat of the reaction accumulates and the reaction becomes progressively faster and thermal runaway may take place to the point of ignition. A detailed computer mo...
متن کاملA comprehensive study on the effect of moisture content on coal spontaneous combustion tendency
There are several phenomenons for polluting the environment, especially in coalfields; which coal spontaneous combustion is one of them. The moisture content is one of the intrinsic characteristics of coal, which has an important role in the occurrence of this phenomenon. Therefore, this research predicts the coal spontaneous combustion tendency based on moisture content. The percentage of mois...

The R70 self-heating test has been used as one of the major laboratory methods for testing the intrinsic properties of coal that influences its propensity for spontaneous combustion. The R70 test is conducted in an artificially created adiabatic environment so that only and all the heat generated by the coal sample is used to prompt the oxidation process and to increase the temperature of the s...
