Dec 04 2017 · Advantages of underground mining less surface disturbance less environmental disturbance less waste mined per tonne of ore ability to mine resources that are not economic as a surface mine cheaper to set up mine development for deep ore deposits Disadvantages Higher cost per tonne mined vs other mining methodsGet Price
Mar 29 2019 · Take a look at some of the reported benefits or advantages of subsurface irrigation systems • There is an immediate reduction in costs simply because there is no need for a worker to water plants since the subsurface irrigation waters automatically • It costs less to water plants more fullyGet Price
Amongst the advantages are that it is cheaper can recover more of the resource usually up to 100 within the mining excavation is safer and can use largerscale mining equipmentGet Price
Subsurface mines produce large amounts of environmentally hazardous acid mine drainage To keep the underground system of tunnels and mine shafts clear mining companies have to pump out large amounts of water which go into surface ecosystems The groundwater from the mines is more acidic than surface waters and disrupts ecosystems by changing the pH conditions of soil and water sourcesGet Price
