Hydraulic fracturing, more commonly known as fracking or fraccing, is used to stimulate and accelerate the flow of coal seam gas. The process involves high pressured injection of sand, water and chemicals into the coal seam gas well. The injection causes fractures in the coal seam allowing the gas to flow to the surface of the well

Primary air is supplied by fan through air pre heaters to coal mill or in some boilers, fan pressurize hot air received from air pre heaters and then supply to mills. Hot primary air drives moisture from coal and acts as carrier to transport pulverized coal to the boiler through pipes. However, the above can be considered as the brief overview of coal mining process flowchart

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) decommissioning the mine and releasing the property for post-mining

The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the coal seam, (5) loading and transporting the coal, (6) backfilling with spoil and grading, (7) spreading top soil over the graded area, (8) establishing vegetation and ensuring control of soil

Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In open-pit coal mining, a pit is dug in an area and this pit becomes the open-pit mine, sometimes called a quarry.Open-pit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great

Jan 25, 2018 · In case of strip mining, coal seams are reached by removing the surface above them. The surface, which is referred to as overburden, is removed in long strips in this coal mining technique. The overburden taken out from the first strip is deposited outside the mining place. This process is referred to as out-of-pit dumping. The void resulting
