COMPARISON OF COAL MINE RECLAMATION UNDER

The depth and volume of material movement in a coal mining operation are much greater than in traditional O&G or coalbed natural gas (CBNG) operations when an equal sized area is compared. However, total surface disturbance in O&G or CBNG has the potential to be much greater than in a single coal mining operation.

Oct 19, 2017 · Indeed, the industry promoted a "coal heritage" that linked Appalachia's significant past to coal production, erased evidence of past abuses, and conveyed mining as a solution to residents' concerns with unemployment, affordability, family and community breakdown, and rural inequality. Coal representatives accomplished this by employing two forms of hegemonic leadership.

FUNDAMENTALS OF COAL MINE ROOF SUPPORT

ABSTRACT Roof supports can only be understood in conjunction with the rock structure that they support. The strength of the rock depends on geology, and the loads are applied primarily by the in situ and mining-induced stresses. Other factors, such as wider spans and retreat or multiple-seam mining, can also reduce the stability of mine openings.

COAL MINING AND THE ENVIRONMENT

Abstract The environmental impacts of coal mining in South Africa are reviewed. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow. Coal washing gives rises to large waste dumps, which may ignite spontaneously and cause air pollution.

ABSTRACT Coal mining is an age-old method of power production in the world. It is also widely known for the associated risks during mining. Although the number of mishaps has dropped dramatically over the years, the number of fatal accidents is still a concern, and any aid in reducing these figures would be important to industry workers.
