Fig. 3 is the demonstration of mining operation in lower miningcoal bed with fire at surface outcrop. If the width and integrity of pillar that isolate mining operation from other coal body can be assured, coal body's surface outcrop will not influence mining operation.

Fine coal processing and coarse coal processing use similar operations and equipment to separate the contaminants. The primary difference is the severity of operating parameters.

Of the total output of coal from underground mines, more than 90% of coal is obtained by the bord and pillar method, the predominant method of mining followed in India, and the rest is mined by the longwall mining method.

BITUMINOUS COAL. Bituminous mining operations are active in 21 counties in the southwest region of Pennsylvania and is the most abundant coal found in our state. Its primary uses are for electricity generation and metal production. The largest number of mine sites are found in Clearfield, Somerset, and Indiana counties.

Coal preparation involves the use of special equipment that operators are often required to inspect, maintain, and troubleshoot. Operating coal preparation equipment properly can help prolong the life of the equipment and maximize the efficiency of the coal handling system.

In addition to these, the methods of firing steam boiler are such that, the system may easily be handled and also, operation and maintenance should be minimum. There are mainly two methods of firing steam boiler with coal as fuel. One is solid fuel firing other is pulverized fuel firing. Let us discuss one by one.

Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Management of coal combustion wastes 5 Burning coal in a coalfired power plant produces a variety of solid residues known as coal combustion products (CCPs), coal combustion residues (CCRs) or coal combustion wastes (CCWs). CCPs are now more commonly called coal combustion byproducts (CCBs) because of their increasing beneficial use.

Auger Mining A method of mining following a surface mining operation where the overburden becomes too costly to remove. The auger usually operates on a horizontal plane, comes in sections, and the diameter depends on the height of the coal.

One example of a longwall mine is Centennial Coal's Angus Place mine. it is part of Rio Tinto's Mine of the Future program. which aims to make mining more efficient and safer through increased automation and remote operation.
