Advantages and disadvantages of open pit mining –

Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery .

Mining

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground

Strip Mining vs Open pit mining : mining

Strip mining is for shallow, mostly horizontal deposits, usually extended over a considerable area. You remove the overburden, take the ore/coal and move another step in. Behind you, land reclamation can begin relatively soon. As such, the 'mine' moves across the

Rock Reinforcement Options in Underground Mines

That makes blast shields the perfect option for underground mining reinforcement. Blast shields are also the best option for specific location protection in underground mines. You might place them in high-risk areas where workers congregate like elevator or lift entrances, lunchrooms, offices and first aid stations.

Surface mining

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Simulations of open pit mines dewatering, their flooding, and environmental impact assessment are performed using groundwater flow models. They must take into consideration both regional groundwater conditions and the specificity of mine dewatering operations. This method has been used to a great extent in Polish opencast mines since the 1970s. However, the use of numerical models in mining

What's The Difference Between Open Pit Mining,

2012/12/10In underground mining, as noted in other solutions, the ore/mineral is accessed via shafts, slopes, or drifts. The ore/mineral is mined at the face (the place the equipment is placed) and is then transported by means of conveyor belts (coal) or trucks (gold) to the shaft (or slope) and is then raised to the outside where it is processed.

Underground drive are dug to get as close as possible to the ore bodies, these are then very carefully blasted, and the ore is then moves into a crusher by machines called 'boggers', once the ore is crushed, it is brought to the surface by shafts or conveyors, when finally it can be processed.
