Input-Output Analysis and Related Methods

2021-3-19  Input-output analysis is one of a set of related methods which show how the parts of a system are affected by a change in one part of that system. Input-output analysis specifically shows how industries are linked together through supplying inputs for the output of an economy. Suppose there are only two industries producing Coal and Steel.

2021-2-4  Thermal coal is the source of the fuel that feeds coal-fired power plants. And what is the device used inside of a coal-fired power plant that takes coal as an input to generate electricity? A steam turbine. That's right, coal is burned to produce the heat necessary to turn water to steam (steam coal, right?). A simple depiction of this process:

Precision weighing control of coal mine paste

1. Introduction. The technology of coal mine paste backfilling (CMPB) technology is a new green technology to deliver paste filling-materials through pipeline to underground with help of the industrial filling pump or dead weight [1, 2, 3, 4].Paste filling materials are a mixture of fly ash, poor soil, coal gangue, slag, sand and other solid wastes around the coal mine with a certain

Probabilistic Prediction of Acid Mine Drainage

In this paper, we investigate a probabilistic approach in order to predict how acid mine drainage is generated within coal waste particles in NE Iran. For this, a database is built based on the previous studies that have investigated the pyrite oxidation process within the oldest abandoned pile during the last decade. According to the available data, the remaining pyrite fraction is considered

Surface Coal Mining and Reclamation ArcNews

Surface Coal Mining and Reclamation. Surface coal mining involves disturbing overlying rock layers (overburden) to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips (pits) across the coalfield until the area is mined.

Refined coal Wikipedia

2021-3-14  Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.
