2. level 1. · 7 mo. ago. Strip mining was always a little worse than cave diving. Now that caves are just so much larger, they had to drop the ore distribution by a lot so that it wasnt completely ridiculous. (I still think the redstone and diamond distribution needs to be dropped a little in the Deep-Dark, tbh.)
strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling …

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, …
Strip mining is a surface mining technique used when mineral deposits are close to the Earth's surface. During this process, horizontal strips of overburden are removed from above a mineral deposit. These trenches are then excavated, and the exposed mineral extracted. Meanwhile, the overburden from each strip is deposited into the one before ...
Two mining sequences of the strip filling mining mode are set in the west 510 mining area of the Liudong Coal Mine. Order 1 involves first mining and then filling. In this sequence, strip mining is completed first, and then, a paste filling replacement is used to mine strip the coal pillars. Order 2 involves first filling and then mining.
Strip mining accounts for about two-thirds of the world's solid minerals, and is predominantly used to extract sand, gravel, phosphates, coal, copper, iron and aluminium. Surface or strip mining is often preferred to sub-surface (underground mining) by mining companies for several reasons: It is less expensive,

Diamond and gold production are now well down from their peaks, though South Africa is still number 5 in gold [3] but remains a cornucopia of mineral riches. It is the world's largest producer [4] of chrome, manganese, platinum, vanadium and vermiculite. It is the second largest producer [4] of ilmenite, palladium, rutile and zirconium.
Strip mining is a type of surface mining where the overlying vegetation, rock, and soil (overburden) is removed in order to reach the underlying coal seam, which usually lies a few feet beneath the surface. Explosives are used to fracture any overlying rock, and then heavy machinery is used to remove the overburden and dump it into a nearby area.

Impacts of strip mining: Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.

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 ...

The Cons of Strip Mining. 1. Bad For The Environment. Strip mining can have unwanted effects on the natural ecosystem of the area where the mining is taking place. Plant and animal life is often killed off, taking years to regenerate. In addition to the death of plants and animals, the land also experiences increased susceptibility to erosion ...
List of Pros of Strip Mining. 1. It is much more efficient compared to underground mining. Those who advocate for strip mining believe that the recovery rate of materials is higher using the method. It is estimated that about 80 to 90% of the material can be recovered compared to the 50% recovered using tunnel mining.
Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the …

The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of overburden (if needed), stripping, removal of the coal or other mineral commodity, and reclamation.

Not content with getting minerals from dry land, companies are now aiming to strip mine our ocean floors in search of nickel, copper, cobalt, gold and other valuable metals and minerals. Many of them would end up in our electronics. But there's a heavy price to be paid: Like mountain-top removal mining, deep-sea mining involves massive cutting ...
