Open pit mining involves the process of disrupting the ground, which leads to the creation of air pollutants. The main source of aires from the transportation of minerals, but there are various other factors including drilling, blasting and the loading and unloading of overburden. These type of pollutants cause significant damage to public health and safety in addition to damaging the air quality. The inhalation of these pollutants can cause issues to the lungs and ul
The first task in open pit mining is to remove the top soil, subsoil, and overburden rocks in sequence. The overburden is dumped separately. It can be reverted for replacement in reverse order. The next stage is to open the mineralized ground as the first slot, known as a box cut.

01/07/2020· Open pit mining is just so destructive and awful I don't know how it can be allowed anywhere, let alone in the places it's often done. They basically just strip off huge chunks of land so that nothing can grow there and in the process they end up polluting nearby water supplies and disrupting every other local natural process, since they use loud, obtrusive machinery.
The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open pit 90 of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.

22/06/2018· The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of The next step, once the ore is excavated, is to separate the waste rock and ore using primary crushers, located at the open pit mine site. At this point, larger rocks are broken down to a size better suited for the conveyor belt to transport. From there, the ore is
Open pit mining, or open cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.
Large stripping machines with excavating wheels used in surface coal mining are employed in other types of open pit mines. Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam driven pumps could be used to remove water from the deep mines of the day.
