#0183;#32;Some mining methods cause further destruction, such as the use of explosions to destroy mountain tops. Toxic chemicals and minerals could go to streams, rivers, and other bodies of water which can create harmful effects to marine species. Pollution; Mining can leak pollutants into the environment that may lead to water contamination.
This manual was produced under a contract let by the Bureau of Mines to Skelly and Loy Engineers and Consultants. Information relating to the content of the manual was gathered through contacts with mining companies and equipment manufacturers across the country. Review of mining practices in some foreign countries also provided input.
appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods . This section reviews surface mining methods and
typology of the mined substance(s), waste deposit(s) and mining systems and oreprocessing method(s), an estimation, on the basis of the different processes employed throughout the production chain in mining operations and their management at each level, of the
Reclamation processes. As part of the life cycle of a surface coal mine, completed mine areas must undergo mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a higher and better postmining land use (PMLU) that has been approved as part of the original mining permit application.
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
