Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to ‘fill the gaps’ on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
Coal mininG 1 Underground M: Since 1900, accidents have killed over 100,000 U.S. miners; over 200,000 have died from black lung disease. E: These deaths and illnesses are reflected in wages and workers’ comp, costs considered internal to the coal industry, but long-term sup-port often depends on state and federal funds.
May 26, 2020· In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia. The higher cost of coal from underground mines reflects the more difficult mining conditions and the need for more miners.
Jun 24, 2015· specifically designed for coal mining, note that the costs obtain from this equation need to be readjusted since it is an estimate cost. A System Dynamics Model Of Mining Costs
Mine cost estimation may be done at many levels. At first it may be a simple “back of the envelope” estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.

The capital cost of mining was calculated using the equations below, where D is the daily capacity of the mine in tons of ore produced per day. The constant (i.e., first) term in each calculation is a blanket estimate based on published average initial capital investment in the industry (~USD 500 million for what is defined in this analysis as

Including the cost of machines and coal reserves, the total mining cost in Appalachi basin is closer to $80.00/short tons, while miners in Powder River Basin again enjoy much lower cost of ~$11.63
The total cost of mining includes the direct mining cost and social cost. The social costs include the impacts to the environment and socio-economic systems. According to the estimates for the complete costs of coal, coal mining only accounts for 22% of total social (external or “hidden”) costs of coal
