Bauxite is the main raw material used in the production of aluminium, which has been an important force for technological improvement in numerous industries. 1 Bauxite is gradually located at greater depths because the availability of shallow bauxite has been almost exhausted using open-cast mining. 2 The drill-blasting method has been commonly adopted in the …
1.1 PHASES OF A MINING PROJECT
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 ...
OPTIMIZATION OF PRODUCTION PLANNING IN …
In underground mining, development required to reach the orebody is much and increases the production time from the start of the development (Haycocks, 1992). Effective mine planning is required to generate profit (Carlyle et al., 2001). Mine production scheduling is an important problem in mine planning (Gershon, 1983).
Environmental Risks of Mining
Underground Mining. 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.
