The actual mining occurs at this step It is done in a narrow strip in an elongated form First the primary strip is mined for coal After it is extracted thoroughly the second strip is created by removing filth rock and waste from the top This debris is dumped on top of the first and used strip The process repeated till the last strip is reached...

SURFACE MINING ≠ STRIP MINING Although sometimes mistakenly referred to as strip mining oil sands is actually mined from an openpit below several meters of mining is the mining of a relatively flat deposit very close to the surface commonly used in coal or phosphate industriesMore Details
Surface mining is more economical than underground mining It is most commonly used in the US Because most of the coal is found just under the surface reclaiming the land after the closure of mine is far simpler The different types of surface mining that can be used are 1 Strip mining 2 Auger Mining 3 Openpit mining 4 Mountain removalMore Details
Hydraulic mining is commonly used in reclamation of old mine tailings that still contain payable values of tungsten Underground mining Underground mining is preferred when surface mining is or becomes expensive A major factor in the decision to mine underground is the ratio of waste to ore strip ratio Once this ratio becomes largeMore Details
Conventional mining usually occurs around 1000 metres below the surface Solution mining can access potash reserves at depths exceeding 1600 metres below the earths surface The majority of Saskatchewan potash is mined by the conventional mining method where large mining machines are used to extract the ore by cutting tunnels into the ore bodyMore Details
Mining Crystals For ore mining in a barge it is possible to use Mining Crystals with Tech 2 Strip Miners Tech 2 Strips are actually less efficient than Tech 1 Strips unless you are using Mining Crystals Mining Crystals come in Tech 1 and Tech 2 varieties by ore type but the skill training requirement for them is not very intenseMore Details
