Underground mining has severe environmental

Abstract New geologic studies suggest that underground mining of coal may cause more environmental damage over long periods of time than surface strip mining followed by proper reclamation, according to the U.S. Geological Survey (USGS).

EFFECTS OF SURFACE MINE BLASTING ON

Blast-induced ground vibrations from surface coal mine blasting may have a detrimental effect on nearby underground coal mine openings. The effects of these round vibrations generated from surface mining also have been of increasing public concern. Numerous studies on measurement and analysis of ground vibrations, and heir effects on structures and people were conducted by the U.S. Bureau of Mines.

Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and the depths involved. For example, if the ore is very high grade or carries a high price, then a higher cost method can be used.
