Spontaneous Combustion in Open Cut Coal Mines ACARPCoal Stock Pile Spontaneous Combustion Early Detection

Open cut coal mining produces large quantities of waste material that must be disposed of around the mine site Some of this material may be sufficiently reactive to begin to self heat which can ultimately lead to spontaneous combustion in the spoil piles at some minCoal Stock Pile Spontaneous Combustion Spontaneous combustion is a common occurrence when storing coal for extended periods of time This may also be problematic when stockpiling waste/spoil materials that contain large quantities of coal

EH 93 4 The Fire Below Spontaneous Combustion in Coal Spontaneous Combustion of Coal Practical Maintenance

content coal will burn by itself Spontaneous combustion has long been recognized as a fire hazard in stored coal Spontaneous combustion fires usually begin as hot spots deep within the reserve of coal The hot spots appear when coal absorbs oxygen from the air Heat generated by the oxidation then initiated the fire4 Spontaneous combustion of coal practicalmaintenance subtracting the percentages of moisture volatile matter and ash from a sample Since gas to solid combustion reactions are slower than gas to gas reactions high fixed carbon content indicates that the coal will require a long combustion time Calorific Value
