Common Mining Applications for Compressed Air. Mining applications where compressed air is especially useful include: Pneumatic Tools – Compressed air is an excellent source of energy for power tools such as drills, wrenches, hack saws and other vital mining equipment that needs to be used in the deep underground stretches of the mines.
cfm) of air from the gallery. To simulate air flow in an underground mine, air was directed toward the entry face using a 2.2 m (7 ft) high brattice curtain that was supported by a wood frame constructed 0.6 m (2 ft) from the left side of the entry. The end of the blowing curtain was …
Air has a lot of trouble circulating far underground. Even if it weren't for the equipment spurting out various pollutants, some sort of ventilation would be necessary just to keep the miners breathing. In the past, ventilation in underground mines was a serious problem.
Good ventilation is extremely important in underground mines. A well designed ventilation system can be used to control the temperature, quality of breathable air and in modern mines disperse radon gas. Air doors were used to prevent the passage of air through a mine working, in locations where access to the sealed area is still needed.
Whether the underground rock and water are hot or cold or whether the surface air is hot or cold, in general, the mining company dependent on natural ventilation has practically no control of the direction of the current, hence, in the case of a fire, it is helpless; and when there is no circulation provided by nature's forces, there is no ...
Mucking machines are small compressed air operated front end loaders designed for underground mining. Mucking machines were the first that were introduced in Bisbee mines in the late 1930's to early 1940's replacing hand mucking in the crosscuts and later into some stopes.
air into the mine, equivalent orifice (or) resistance of a mine, ... underground mine with a method of mining/technology (i.e. Bord and Pillar mining method). In which we have analyzed from the below-mentioned seams in mine they are, 1 seam average thickness of 2.5 mts to 3.30 mts.
We set up an 1,800 kWr (600 refrigeration tonne) air-conditioning system by connecting underground bulk air coolers to the fresh air above and chillers in the return ventilation. Having all the coolers underground meant less power was needed to get the fresh air …
Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The largest component of the operating cost for ...
Air Blast in Underground Mine. in this post you will found air blast underground mining definition and explanation about it, how air blasting happens and major causes of air blast, dangers of air blast and how to avoid air blast. some of the major accidents of air blasts list. air-blast-image.
The establishment of an air shaft is essential to any type of mining that requires workers to be underground. Air shafts are open spaces that are created for the purpose of allowing ventilation into an enclosed space. Some examples of air shafts are simply holes that are bored from an underground operation to the surface, thus ensuring a steady ...
2. Underground mining. Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when:
Glossary of Mining Terminology After Damp - Gasses resulting from underground combustion, normally carbon monoxide. This is a loose term implying any fatal gas in a mine after an explosion or fire. Air Shaft - A vertical opening into a mine for the passage of air. Airway - Any passage in a mine along which an air current moves. Some passages are

The mining industry, whether underground or surface mining, never sleeps. Mining work is completed in harsh conditions, and mining processes run 24/7 – often in remote locations miles away from the nearest town. Two key pieces of equipment that are used to power these processes are air compressors and low-pressure blowers.
