what are the advantages and disadvantages of surface mining?

Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination. Surface mining, also called strip mining, delivers economically vital supplies of coal, which powers transportation and creates consumer products, boosting local economies. This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier.

Supporters of surface mining contend it promotes clean energy, producing less environmental disturbance than pit mining. However, opponents of surface mining cite many issues with its operations. It draws criticism for polluting and changing local streams, filling them with rocks and potentially harmful toxins. Surface mining also requires the clearing of large tracts of land, which necessitates removal of many acres of forest. The cutting of trees invites erosion, as tree roots anchor soil and earthen material to the land's surface. Altering the landscape also impacts the local plant and wildlife populations, as plants and animals lose their homes to the mining operations. The risk of spills and leaks increases with surface mining, and the establishment of mines jeopardizes the value and structural integrity of surrounding homes and real estate.

what are the disadvantages of subsurface mining?

Although there are opponents and proponents of underground mining, the disadvantages include destruction of land, surface subsidence, abandoned shafts, extensive surface spoil heaps, mine explosions, collapses and flooding.

Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination.

The Abandoned Mine Land (AML) Reclamation Program uses fees paid by present-day coal mining companies to reclaim coal mines abandoned before 1977. This makes these areas safer for people and the environment.

This Act establishes a program for the regulation of surface mining activities and the reclamation of coal-mined lands, under the administration of the Office of Surface Mining, Reclamation and Enforcement, in the Department of the Interior.

The Surface Mining Control and Reclamation Act of 1977 (SMCRA) is the primary federal law that regulates the environmental effects of coal mining in the United States. SMCRA created two programs: one for regulating active coal mines and a second for reclaiming abandoned mine lands.

Why cleaning up abandoned coal mines is so important and difficult. With coal production at its lowest level in 30 years, abandoned mines around the country are causing major environmental problems. They can catch fire, and debris from them can contaminate the water supply.

Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local
