Because there are so many applications for compressed air in mining, most mines utilize more than one compressor on site. The most common applications include: Exploration drilling: During exploration drilling, an air compressor is used to drive a rotating drill bit deep into the ground. Smelting: This process of melting and heating is …

rapid impacts to the drill steel, thereby transferring energy to the drill bit. The "blows" to the rock downhole are delivered by the bit, while a rotational device ensures that the bit impacts a new rock surface with each blow. A feed force is applied to maintain rock/bit contact. Compressed air is used to remove or "flush"

bags and cleaning or replacing air filters. Wet Methods Wet methods are generally not appropriate for use with electric rotary hammers; however, pneumatic drills can be used for wet drilling and some come equipped with water-feed capability. Wet drilling is commonly used in the tunneling and mining industries to limit dust getting in the air.

A pneumatic tool is a device that uses highly compressed air as its power source. Typically, a diesel engine drives the air compressor, which then forces the air through a hose to the end tool -- in this case a jackhammer. The body of a jackhammer is a vertical cylinder, which acts as a pressure chamber.

History. Pneumatic drills were developed in response to the needs of mining, quarrying, excavating, and tunneling. The first "percussion drill" was made in 1848 and patented in 1849 by Jonathan J. Couch of Philadelphia, Pennsylvania. In this drill, the drill bit passed through the piston of a steam engine.
