Open cast mining is generally considered safer than underground mining but there are still some dangers such as:
1)Because opencast mining is done in the form of ledges one can easily fall off one of these ledges which can can meters high.
2)Because open pit mining is done using explosives it can cause injury due to flying pieces of rock and other debris.
3)Open cast mining needs a lot of space for digging and it affects the environment in many bad ways.Animals loose their homes,deforestation occurs,people have to be relocated to other places because of pollution hazards.
4)The use of explosives may also cause other accidents to happen.
open pit mining spoils lots of the countryside and they are hard to expand when needed.

All hazards on the mine
Advantages to the mining industry in general are that it can add jobs and money to the nearby economy. Some disadvantages are that the work is dangerous, and it is depleting the earthâ??s natural resources.
There can be disasters, like the Chilean Mining Disaster. The men were mining in the San Hose gold and copper mine, the tunnel caved in and the men got stuck for 69 days. People have to be very careful of mining cause they can die from these disasters such as explosions and caving in.
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining. * It is also faster The disadvantages of surface mining are: * That it destroys the landscape and environment * Effects the habitats of fauna potentially effecting the existing ecosystem in that area * Flora is destroyed * Causes noise, air and water pollution
Uranium mining can be either by open pit mining or by underground mining.
Miners that breathe in radon ( a uranium gas) are at risk of lung cancer and other diseases. It pollutes our air water and land, and can never be properly cleaned up.

Strip mines,Openpit mines & shaft mines
Yes. This is correct, but next time you might want to check your k12 earth science book for help. =)
It depends on the method of mining adopted. in case of openpit mines with large size fleet the biggest cost items are diesel, tyres and spares In case of manual underground mines the biggest cost items would be wages

There are many disadvantages to mining. The main disadvantages include the danger to the miner, environmental hazards, the stripping of natural resources, and the permanent scarring of the landscape.

Subsurface mining is less disruptive to the environment that strip mining, however the danger to the miners is greater
