Estimating tons of coal on a property Kentucky

This value is important for determining how the coal is washed (cleaned or beneficiated) to remove mineral impurities that lower the coal's heating value So the conversion factor a specific mine or coal company might use to estimate the tonnage of a particular seam may differ from 1 800 tons/acre-foot depending on the coal and reason for the calculation

CBM case studies

Coal rank in the fairway ranges from medium- to low-volatile bituminous and roughly coincides with those portions of the basin that were most deeply buried Coals in the fairway typically have low ash and high vitrinite contents resulting in large gas storage capacities and excellent permeabilities of 10 md from well-developed cleat systems

Coal Washing

Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties In addition to the coal itself pieces of rock sand and various minerals are contained in the mixture Thus before coal can be sold to consumers it must be cleaned The cleaning process consists of a number of steps that results in a product that is specifically suited to

Water for Coal

Depending on its quality coal may need to be "washed" with water and chemicals to remove sulfur and impurities before it can be burned in a power plant According to the US Department of Energy total water used for coal mining in the United States (including water use for coal washing and cooling of drilling equipment) ranges from 70 million to 260 million gallons a day [9]
