4 Coal Mining and Processing Coal: Research and

Relatively shallow coal deposits are generally extracted by surface mining, and deeper deposits are extracted by underground mining (more detailed descriptions of surface and underground mining processes can be found in Appendix E)Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal Source: Energy Information AdministrationCoal Mining and Processing Energy Trends InsiderBefore mining begins, a rotary drill is used to define the lignite field, the depth and thickness of lignite seams, and the amount and type of material (or "overburden") overlying the lignite This information is used by BNI engineers to determine where the best lignite deposits are locatedMining Process BNI CoalCOAL MINING PROCESS DEVER C ASHMEAD 423 to remove rock from the coal This was particularly true of the Schuyl kill region where the measures pitch steeply and the coal sooil reached an excessive depth, judged by the standards of that generationCOAL MINING PROCESSCoal mining Contribution to environmentallyfriendly energy production Coal preparation is essential and significant in providing clean coal for society and utilizing our resources efficiently Schenck Process’s competence in coal separation, screening and feeding is tailormade to its need for nearly half a Coal mining Schenck Process

Common Coal Mining and Processing Terms

Continuous Mining is an underground method of extracting coal The process utilises a machine that is capable of handling the entire extraction process The machine itself takes over the traditional cutting, drilling, blasting and loading stages of underground coal extractionLongwall mining involves the full extraction of coal from a section of the seam, or 'face' using mechanical shearers The coal 'face' can vary in length from 100350m Selfadvancing, hydraulicallypowered supports temporarily hold up the roof while coal is extracted When coal has been extracted from the area, the roof is allowed to collapseCoal mining World Coal AssociationMining Process Sixty million years ago, the area where BNI now mines coal was a vast swamp Plants died, fell into the water and decayed slowly Eons later, the climate changed and rivers deposited material over the decaying vegetation The weight of the overlying material pressed the Mining Process BNI CoalIn surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction 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 Appendix E: Coal Mining and Processing Methods Coal COAL MINING PROCESS DEVER C ASHMEAD 423 to remove rock from the coal This was particularly true of the Schuyl kill region where the measures pitch steeply and the coal sooil reached an excessive depth, judged by the standards of that generationCOAL MINING PROCESS
