The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ScienceStruck explains what these methods are, with the applications of each one.
Underground mining hard rock Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands. Mine Access
2 Coal mining - Coal mining - Choosing a mining method The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many

2020-5-24There are four main mining methods underground, open surface pit, placer, and in-situ 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 environments.
There are hard-rock underground mines, and there are soft-rock underground mines. Coal deposits, for instance, live in relatively soft sedimentary rock. Gold deposits live in igneous or metamorphic rock, which is relatively hard, as do diamonds, copper, silver, nickel and zinc source Great Mining . Even within the hard-rock category, design ...

Web hits and downloads continue as students and
2020-5-23Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam profitable bed of coal is located, extracting this black gold can require
Surface mining can be accomplished by the following main methods Open-pit Mining Removing ore to leave a crater. Quarrying An open-pit mine for construction materials. Strip Mining Ore is removed in parallel strips. Mountaintop Removal Top of a mountain is blasted to remove deep ore. Dredging Ore is removed from a river bottom. The main methods of underground mining are
