Black Lung
Lung Cancer
Thermal Stress
Body vibrations
Musculoskeletal Disorders are
Injuries or disorders of the muscles, nerves, tendons, joints, cartilage, and spinal discs.
Caused by excessive temperatures
Exposure to contaminated water
None of the above
Which of the following is NOT associated with rock blasting?
Air blasts and ground vibrations caused by explosive detonation can have desultory and damaging effects to public and private property
Impose adverse effects on underground mining operations.
Exposure to contaminated water
Change the course of flow or effect the availability of surface and groundwate
What is the impact (effect) of flooding in the mines? (2 marks)
Change the course of flow or effect the availability of surface and groundwater.
The flooding process happens because the drainage wells or dewatering pumps stop to work and the open mining spaces are filled with groundwaters and surface waters.
Mining can trigger the formation of sinkholes.
Waters that flood open pit mines can range from drinking water quality to acidic waters that can kill animals if drunk.
How does mining result in water pollution?
Groundwater withdrawals may damage or destroy streamside habitat many miles from the actual mine site.
Acid mine drainage also leaches toxic metals, such as arsenic, cadmium, chromium, lead, from ore and waste rock, causing additional water pollution.
Water tables can become contaminated if untreated.
All of the above
Sustainable mining involves sustainability in terms of economic, environmental and social sustainability? True or False.
True
False
