Of all the fossil-fuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States. However, burning coal in electric power plants is a major source of carbon dioxide (CO2) emissions, and its use has other repercussions as well. Mining coal disturbs the land and modifies the ...
In most cases, a general safety glove in cotton or leather will work just fine. PPE must be carefully selected for the situation at hand. Safety managers and employers should evaluate the risks and hazards present at the mine site and make educated choices as to what PPE should be purchased for their workers.

In a standard float-sink analysis, set amounts of the representative coal sample are crushed to a specified particle size and placed in liquids of known density or across a range of densities. Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such as pyrite (4.9 to 5.2).
The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong. The strong pieces of coke with a high energy value provide permeability, heat and gases which are required to reduce and melt the iron ore, pellets and sinter.
