What is belts mining?
strips are a type of surface mining that includes removal of a thin layer of material known as "overload" for access to buried deposits of useful minerals. This type of mining is only effective in areas where mineral bearings are very close to the surface, so it is possible to quickly and easily remove the overload to reach them. Classic strips are used for tar and coal. This technique is also referred to as open castings, open cut or streaming. Furthermore, for the placement of explosives, holes are drilled to release overload to remove the ground device. Some of the largest industrial facilities in the world are used in belt mining, while overload is accumulated next to the place or transported for disposal, depending on how the mine is. Once revealed, minerals can be extracted.
In many cases, mining operations work a bit likeLawn mowing: One row at a time. When this technique is used, the mined strips are used to hold the removed overload from the neighboring row, so they may not be towed out of the place. This technique also facilitates control of stability and conditions in the mine, as only a small segment is actively operating at the moment.
surface mining is designed for relatively flat areas of the Earth that can be quickly and easily processed using strips mining techniques. The main problem in flat areas tends to be limited and properly disposal of overload to keep space under control. In the mining of the outline strips, the strips are dug around the contours of the mountain and the miners must be more cautious to prevent collapse and other problems that can cause injury or death.
As one can imagine from the description, the extraction of strips can be very disturbing. Undesirable overload often consists of a nutrient -rich topsoil that could have been built for centuries, and when overload is carelessly disposed ofIt is a huge waste. Even if the overload is exchanged, it may take decades or longer than the life of plants and animals in this area recover. Pollution can also become a problem depending on what is mined and whether it is processed in place.
