What are the challenges of working in a deep mine?
Cave-ins, explosions, toxic air, and extreme temperatures are some of the most perilous hazards observed to take place in underground mining. Valuable minerals are found all over the world.
What are some disadvantages of underground mining?
There are several disadvantages of underground mining that can account for this, including higher costs, a longer develop- ment period, lower recovery of ore, greater safety risks, shortage of underground labor, and the possibility of subsidence.
What are the main challenges in mining industry?
Problems in the mining industry in South africa
- The gap between mining and manufacturing.
- Bridging the gap with beneficiation.
- Making beneficiation work for development.
- Government intervention needed.
What are the risks of mining?
Mining health safety – 7 common risks to protect yourself against
- Coal dust. Dust inhalation or coal dust is one of the most common concerns for miners.
- Noise.
- Whole body vibration.
- UV Exposure.
- Musculoskeletal disorders.
- Thermal stress.
- Chemical hazards.
What is the advantage and disadvantage of underground mining?
Explanation: Shallow mineral or coal deposits can be economically mined by open-pit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective.
How does underground mining affect the environment?
Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. Coal mining produces also greenhouse gas emissions.
What is mining problem?
Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. Contamination resulting from leakage of chemicals can also affect the health of the local population if not properly controlled.
Why is underground mining hazardous?
Strata Control. In underground mining, it is essential to control the strata to maintain stability. Other underground mining hazards are associated with fire, flood, inrush, gas, vapors, dust, blasting, machinery, noise, heat, and airborne particulates.
What are the disadvantages of mining?
Disadvantages of Mining
- Mining can lead to soil pollution.
- Groundwater pollution.
- Deforestation.
- Depletion of natural resources.
- Mining implies the destruction of habitats.
- Endangerment of species.
- Loss of biodiversity.
- Landslides become more likely.
What are three environmental problems of underground mining?
The effects can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
What does underground mining do?
Underground hard-rock mining refers to various underground mining techniques used to excavate “hard” minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies.
What are the disadvantages of 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.
What are the challenges of deep mining engineering?
These challenges include the catastrophic events that are often met in deep mining engineering: rockbursts, gas outbursts, high in situ and redistributed stresses, large deformation, squeezing and creeping rocks, and high temperature.
What are the main causes of disasters in deep mining?
The characteristics of the rock mass and the boundary conditions in deep mines are the primary causes of disasters in deep mining [2].
What are the environmental issues associated with mining?
In addition to the issues addressed above, there are many other environmental issues associated with mining: Carbon output. Mining, like most heavy industries, is dependent on fossil fuels, which generate the energy needed to operate a mine.
