These deposits usually occur beneath barriers like a rock layer, forests, or oceans, which makes accessing them difficult Depending on how these ores are extracted, mining methods can be categorized as ‘surface’ or ‘underground’ types In surface mining, the rock barrier on top of the deposit is removed to access the ore However, sometimes, such deposits occur too far below commonly in underground mines, including classification of underground mining methods and brief explanations of the techniques of roomandpillar mining, sublevel stoping, cutandfill, longwall mining, sublevel caving, and block caving The second section describes underground mining equipment, with particular focus on excavationUnderground Mining Methods and Equipment EOLSSIn the illustration below, circle the words that apply to the mining method Skip Tailings Stope Crusher Bolting Ramp Muck aise ackfill ial Cave Ore body en pit Load Haul Dump Drilling and blasting Ore pass Jumbo Pillar Mineral Drift Room Underground Mining Methods Sequence Chart 3There are many new terms and concepts related with underground mining methods To Underground Mining Methods Mining Matters
