What are the advantages and disadvantages of subsurface mining? Advantages : Safer than surface mining, faster than 60% of other mining in the, less disruptive to the environment, leads to more minerals. Disadvantages : Costs more, harder to do than surface mining, takes a lot of time.
Subsurface mining often progresses below the water table, so water must be constantly pumped out of the mine in order to prevent flooding. When a mine is abandoned, the pumping ceases, and water floods the mine. This introduction of water is the initial step in most acid rock drainage situations.
Although 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 a ...
Nov 27, 2014· It Is Cheaper Than Traditional Forms Of Coal Mining The clean coal mining industry looks to reduce atmospheric pollution while also reducing the costs of obtaining the coal that needs to be burned for power. Mountaintop mining, when done correctly, is able to accomplish both of these goals rather effectively. Cons of Mountaintop Removal
Placer mining. Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.
Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.

For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth''s surface. Those who support strip mining point to the increased ease of access and all ...
It is large enough for men and machinery to move about, is cost efficient and safe compared to open shaft mining. Cons: Leads to habitat loss, creates large holes in the ground and those holes allow water to drain into them where they could become acidic.
Nov 09, 2009· Best Answer: Surface mining is much easier than subsurface mining, because it''s right there... on the surface, so you can "scrape it up with a shovel" (of course, there''s more to it than that, but that''s the essense). You don''t have to drill down hundreds or thousands of feet, then drill sideways, and so on. Subsurface mining is more dangerous because of this.
Surface mining techniques don''t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground [.]
Sep 24, 2015· 5 Chief Pros and Cons of Strip Mining. Sep 24, 2015 Aug 29, 2015 by Editor in Chief. Surface mining refers to a category of mining where soil and rock overlying the mineral deposit are removed. There are several types of surface mining, and strip mining counts as one of them.
Apr 02, 2018· Disadvantages of open pit mining. One of the main disadvantages of this type of mining operation is the environmental impact it causes.
