Although underground mining is a less environmentally-destructive means of gaining access to an ore deposit, it is often more costly and entails greater safety risks than strip mining, including open-pit mining. While most large-scale mining projects involve open-pit mining, many large underground mines are in operation around the world. 1.1.3 ...


Within the underground mining sector, falls of ground comprised about 28 percent of the fatal and 16 percent of the lost-workday injuries from 2000 to 2004 (NIOSH, 2005).
