NIOSHTIC-2 Publications Search 10009405 Cost Analysis

This study estimates costs of producing bituminous coal and lignite by stripmining methods in 12 hypothetical mines. Basic costs are developed by geographic area, rank of coal, and output capacity. Seam thickness and depth and type of overburden are considered typical for the area in which the hypothetical mine would be located. The cost analyses are based on the use of new equipment, the

Costs of Reclamation on Southern Appalachian Coal Mines: A

Strip mining is a form of surface coal mining where overburden is removed to expose the underlying coal seam. There are three general types: area mining on flat terrain and contour and mountain top removal mining on steep terrain. Area mining is practiced on relatively flat terrain such as mines found in the mid-west and far western coal fields.

A major operation in the recovery of any coal seam by surface mining methods is the removal of the overburden (Fidler, 1979). Of the available surface mining methods, strip mining is arguably the most common method used to mine coal in Australia. Pre-strip by definition is the removal of any waste material not considered to be valuable.

Introduction. There are substantial coal resources left un-mined under surface buildings, water bodies and railways in China. The extraction of these coal resources is termed ‘three-body’ coal mining and has become a major problem in the mining industry.1, 2, 3 The existing mining methods and commonly used techniques in ‘three-body’ coal mining include strip mining, mining with
