Influence of anti-pyrogenic materials on coal mining waste's tendency to self-ignite

Journal of Sustainable Mining

Vol. 15, iss. 4

170--174

The aim of this work was to investigate the influence of anti-pyrogenic materials with use of Combustion By-Products (CBP) on the tendency of coal mining waste to self-ignite in laboratory conditions. The tested material sample was a mixture of coal waste with an addition of anti-pyrogenic material based on coal combustion by-products. The laboratory installation to test the properties of anti-pyrogenic materials is presented. The temperature of the tested sample as well as the concentration of carbon monoxide in exhaust gas were chosen as the parameters which determine the properties of anti-pyrogenic materials to reduce the self-heating process of coal waste. Laboratory tests of material samples were performed in a temperature range from 40°C to 500°C, at time interval of 350 s.
