What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run of Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved. Washability Study • The selection of the logical separation process
Coal mining equipment is subject to needing repair due to the high demands placed on the parts during mining and processing. Coal mining equipment should be maintained by the most knowledgeable professionals available, to ensure optimal safety and efficient production for miners and manufacturers.
Coal mine methane (CMM) is a type of gas present in active, working mine sites. This gas is extracted from the air in the coal mine helping improve safety and preventing uncontrolled release of methane to atmosphere. CMM is a mixture of methane & air released during the process of coal mining and must be vented for safety reasons.
