This number is based on operational knowledge of the tons <br />washed and other factors such as the type of clays encountered, processing equipment <br />efficiencies, etc. <br />The smallest quantity of water entering the mine is the incidental category. This category <br />includes leakage from water lines, dust control watering in the haulage entries, and <br />washdown water used in the slope and other locations. It has been assumed that 10% of <br />the water used for production equipment will be used under this category. <br />Outgoing Water As coal is mined, water is added by dust control sprays on the <br />continuous miners, the longwall shearer and at transfer points along the conveyor belt <br />system. This water is then carried out of the mine as surface moisture on the raw coal. <br />This added coal surface moisture represents a 4% increase in the raw coal moisture <br />content. The raw coal tonnage produced during this reporting period was 2,267,424 tons. <br />Water leaving the mine as ventilation humidity represents a large quantity in the water <br />balance. The temperature of the exhaust ventilation air is almost constant, at 60° F. <br />9
