Energy and Environmental Profile of the Mining Industry 4
Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or openpit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, lowcapacity mines have rapidly disappeared.

Mining methods of the Klondike Gold Rush
The first step of recovery was to bring the mixture of gold and dirt from the ground to the surface or from a hillside down to a bench. There were two methods: digging a shaft or using pressurized water to either wash soil down a hillside or suck it up from the ground. Underground mining [ edit] Most of the gold was below the surface.

Surface mining. Surface mining is exactly what the word says digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.

Bulking/Swell of Excavated or Mined Materials
The same excavation in feet: Excavated area is 200 feet long 20 feet wide and 2 feet deep with a listed swell of 40% for the material. Bank volume = 200 * 20 * 2 = 8000 ft³. Convert 8000 ft³ to yd³ = 8000/27 = 296 yd³. Loose volume = 296 * = 414 yd³. (Calculations are based on the material being of similar consistency.
