How do the high speed brooms remove the snow from the airfield surface?
powerful blast of air
What are the cons of surface mining?
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
Is compressor is the component of oil well drilling rig?
No. The mining industry uses air blast percussion method to drill, so air compressors are needed. See link.
What is the difference of surface mining and subsurface mining?
Surface mining is safer and easier than subsurface mining.Surface mining does more damage to the environment than subsurface.Surface mining creates more of a mess then subsurface or open cut mining.ON TH OTHER HAND-Subsurface mining is very dangerous.Subsurface mining allows you to retreive minerals from underground.Subsurface mining requires you to go underground, where you will have very little air.
What is air blast burner?
An air blast burner is a burner where a controlled blast of air is supplied the gas. The burner has an air blast type fuel injector.
What are someTypes of subsurface mining?

What creates the air blast in a blast furnace?
Hot air under pressure
What was the blast of air that flattened Nicodemus ear as hethe rats and the mice were escaping?
The blast air that flattened Nicodemus was air.
How is surface and underground mining different?
Surface mining is used where the ore or material to be extracted is located fairly close to the surface. The overlying ground cover is removed, the material is mined, and the ground cover is ordinarily replaced. Subsurface mining is used where the material is in veins deep beneath the surface, or obstructed (by rock layers, water tables, or other strata) in a way that make surface access impractical. Early mines used existing caves, but technology has brought increasingly deep and complex drilling to reach veins of coal or metal ores.Surface MiningSafer and easier than subsurface mining.Does more damage to the surface ecosystems than subsurfaceCreates more of a mess than subsurface or open cut mining.Subsurface MiningNot as much widespread damage to ecosystemsDifficult and expensive to digVery dangerous conditions can include collapses, released gases, particulates in the air, low oxygen, and heat
What Is A Blast Furnace?
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
