    OverviewMethods of extractionHistoryProductionModern miningSafetyEnvironmental impactsLegality of coal mining

    The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, and the geology and environmental factors. Coal mining processes are differentiated by whether they operate on the surface or underground. Many coals extracted from both surface and underground mines require washing in a coal preparation plant. Technical and economic feasibility are evaluated based on the following: regional geological conditions; overburdencharacteristics; coal seam continuity, thickne
