What Is The Environmental Impact Of The Coal Industry ...

Coal mining, the process of extracting coal from the ground, is a common economic activity around the world. Coal is removed in a number of ways including: contour mining, strip mining, and mountaintop removal. After undergoing a cleansing process, coal is typically burned in order to produce electricity.

Determining the scale of coal mining in an ecologically ...

A reasonable mining scale is very important for the development of mining areas. In view of the lack of water resources in arid and semi-arid areas, this paper studies the scale of coal mining in arid and semi-arid areas under the constraint of the water resources carrying capacity (WRCC) with the aim of realizing the conservation mining of ecological environment.

U.S. Coal Resources and Reserves Assessment

The portion of recoverable coal resources that can be defined as reserves will vary over time, based on fluctuations in mining costs, differences in mining methods, and the market value of the coal. In energy assessments, it is important to estimate not only the total coal resources, but to inventory the recoverable coal resources and coal ...

Constraints of coal mining safety management efficiency

Methods: An index system for coal mining safety management efficiency (CMSME) is first established. Then a mathematical model roughly identifying the constraint factors is constructed. The principle of the proposed model is a comparison with the changes of the ratio of integrated CMSME and the ratio of each impact factor over a certain period.
