Coal mining

Underground mining. In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata.Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities for such essential activities ...

Coal prices and outlook

 · 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.

Determination of Required Bond Amounts

Ohio''s program did not require cost estimates prior to the 2007 changes to Ohio''s bonding program because Ohio''s ABS established a flat per-acre performance security rate of $2500. This performance security was, and still is, supported by an excise tax on coal production.

Trends in Australian Underground Mining Costs – AMC ...

These costs are "as reported" in monthly operations reports, in the dollars of the day. Once corrected for inflation at the Australian CPI, the increases are more like $3.50/t per year for the small mines and $1.40/t per year for the large mines, expressed in 2016 dollars. Thus we can say that underground mining costs in Australia have ...

 · The decision on whether to operate an above- or underground mine is heavily influenced by a couple of important factors. The major factor in deciding on whether to go underground or open cut is the stripping ratio (Whittles et al. 2007).This is defined as the ratio of the volume of overburden (BCM) moved to the amount of coal produced (tonnes).
