Coal Mining Underground Surface. A production miner supervises the crew and machines involved in the physical operation of mining coal. Just as coal is vital to the future of our country, production miners are vital to the future of our coal mining industry. The industry requires skilled and competent miners, and such miners are trained at CTC.
· Compared with underground coal mines, surface coal mines have better transportation conditions, and flame retardant and antistatic requirements are no longer the main requirements. The physical and mechanical properties should be given priority to, while safety performance should be taken into consideration.
12/04/2020 · Traditional forms of mining can be unsafe for workers. Fires and collapses can be deadly, and the health effects of mining can be devastating. Others, however, object to mining in general. Because coal and oil release carbon dioxide when used as fuel, some argue that mining exacerbates global warming. Others object to mining for the rare Earth ...
Compared to surface mining, underground mining is expensive and dangerous. Therefore, it is used primarily in situations where highvalue ores such as gold are concentrated in narrow veins or other unusually rich deposits. Unlike surface mines, underground mines can also be excavated beneath bodies of water. Salt mines more than 328 yd (300 m) deep, for example, extend beneath Lake Erie .

Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to within the mining excavation), is safer and can use largerscale mining equipment offering higher production rates.
· Economically a better option in some geological settings, but human safety a major issue. Shallow mineral or coal deposits can be economically mined by openpit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective.
