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. In the final stages a detailed bottom-up estimation based on first

Once coal is mined, it must be transported to consumers. Transportation costs add to the delivered price of coal. In some cases, such as in long-distance shipments of Wyoming subbituminous coal to power plants in the eastern United States, transportation costs are more than the price of coal at the mine. Most coal is transported by train, barge
I’ve subscribed to Mining Cost Service continuously for more than 12 years which has greatly assisted in the development of my estimating skills as a Mining Consultant. Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine
• Until the early 1970's, the majority of coal production in the U.S. was via underground mining methods. • Advancements in technology (primarily hydraulics and explosives) and expansion of mining activities in the west (particularly in the PRB), have shifted mining trends from underground to surface production over the past 40 years. Year

Full Cost Bonding for Land Reclamation on Pennsylvania’s Coal Mine Sites is the regulatory program for calculation of the amount of bond necessary for specific mine sites. The Surface Mining and Reclamation Act requires the amount be based on the total estimated cost to the Commonwealth of completing the approved reclamation plan.
The ERR is derived from the DRB by applying coal mine recovery and accessibility factors by state to the DRB. The ERR is categorized by state, Btu (British thermal unit) value, sulfur content, and mining type—it is the most widely reported and frequently quoted estimate of U.S. coal reserves.
was developed to estimate capital and operating costs associated with various mining methods. This technique, developed under a Bureau contract by STRAAM Engineers, Inc., was completed in 1975, then updated in 1983. During the course of the update, it was noted that few provisions were made for estimating the costs of small-scale mining
Cost-effective abatement potential ($0 break-even price) is 77.7 tCO2e, or 10% of baseline. • The technological maximum potential ($100+ break-even price) is 467.6 tCO2e, or 60% of baseline.

Globally, coal is the largest source of electricity generation, reflecting both its reliability as a base-load energy source and its relatively low cost. Of the estimated total global electricity generation of 26,600 terawatt hours (TWh) in 2018, around 10,000 TWh was generated using coal (Graph 3).
