(PDF) COAL MINING METHODS ResearchGate
The methods of mining of coal varies from deposit to deposit This report highlights the coal mining methods, their significances, issues of concern and the stages of using coal after miningIn roomandpillar mining, coal deposits are mined by cutting a network of ‘rooms’ into the coal seam and leaving behind ‘pillars’ of coal to support the roof of the mine These pillars can be up to 40% of the total coal in the seam – although Coal Mining FutureCoalCoal occurs in a wide range of forms and qualities There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other bituminous and anthracite coals Coal Mining and ProductionIn “conventional” roomandpillar mining, production occurs in five steps: mechanically undercutting the coalbed, drilling holes into the bed for explosives, blasting the coal, loading Coal Mining Methods Midwest Industrial Supply
