Impact Of Open Cast Coal Mining In N E Jamaica

  • Negative impacts of opencast mining on the environment

    A major part of iron ore, nonferrous metals, brown coal, building materials and minerals for industry is being excavated in opencast mines This type of mining has a deep impact on the natural strata Opencast mining changes geological, hydrological and geotechnical conditions It influences the existing ecological system and landscapeImpact of displacement on place attachment, landscape value and trust in the Sonepur–Bazari open cast coal mining area, Raniganj Coalfield, West Bengal Article(PDF) Environmental and social impacts of mining andCoal is mined either by surface methods (opencut or opencast mining) or by underground techniques In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and useOpencast Mining an overview | ScienceDirect Topics
