what are advantages and disadvantages of mining?
307771
Disadvantage of mining. Disadvantages: It is harder than surface mining and it also costs more money and takes more time. Advantages: Leads to more minerals and ore, also creates less pollution.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.

Diamond mining also has many detrimental impacts on the environment including soil erosion, deforestation, and ecosystem destruction. A major political effect of the diamond commodity chain, specifically at the mining level is blood diamonds. These are diamonds that are produced in war zones to finance civil wars.

The advantage of each also has some possible disadvantages. For example if you block a river with a dam you change the way the river will allow fish to migrate upstream, the flooding downstream that used to provide nutrients to fields along the river is less likely (this can be either and advantage or disadvantage).

The major advantages are flexible budgets, focused operations, lower costs, and more disciplined execution. The disadvantages include the possibilities of resource intensiveness, being manipulated by savvy managers, and bias toward short-term planning.

Environmentally sustainable mining In order to be more environmentally sustainable, mining operations are increasingly conducted in a manner that minimizes their impact on the surrounding environment, and leaves mine sites in an acceptable state for re-use by people or ecosystems.

The environmental impacts of mining, although significant, are generally confined to local areas. Apart from direct physical impacts of extractive activities, contamination of air, land and water may also result.

Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

Surface mining removes ore deposits that are close to the surface, and subsurface mining removes minerals that are deep underground. While mineral use is very important to us, there are also many environmental impacts, such as erosion, air and water pollution, land destruction and harm to mine workers.

Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a “subsidy” of newly created coins.
