Abstract

Coal mine fi re interrupts sustainable mining, and the major cause for this is smouldering combustion. Therefore, it is essential to assess the self-heating susceptibility of coal seams so that precautionary measures can be taken against the occurrence of fi re. The paper describes effect of moisture content of coal on its smouldering combustion. Moisture content of coal samples was increased by subjecting them to enhanced aqua vapor pressure. A new electrochemical method, viz., wet oxidation potential (WOP) technique, is used for assessing the susceptibility of coal to smouldering combustion. In the present investigation, 152 experiments using seventy-six coal samples collected from fi ery and non-fi ery seams in India were carried out. The WOP method demonstrates that rate of reduction of potential difference (RPD) increases in coal samples with enhanced moisture, indicating that oxidation rate is higher. Results of the study corroborate well with the field observations.
