Coal mining Coal mining Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam Once a seam has been discovered, considerable further work issection describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers 1 Underground Mining Methods 11 Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the groundUnderground Mining Methods and Equipment
What are the main methods of mining? | American
There are four main mining methods: underground, open surface (pit), placer, and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsAcademiaedu is a platform for academics to share research papers(PDF) SURFACE MINING METHODS AND EQUIPMENT |
