mine air

The rescuers had to take a break at 1:30pm due to the mine air being to contaminated.

She could smell a cold exhalation of damp mine air coming from below.

It includes a fully equipped mobile laboratory able to respond to any emergency requiring mine air or environmental analysis.

The methane whistle indicated methane levels in the mine air from 1 vol% and above.

It is used in the field of mining engineering for calculations relating to the temperature regulation of mine air.

Like almost all of the veteran miners his lungs are in poor shape after years of breathing the dusty mine air without safety masks.

• Low ventilation prescription numbers can contribute to a better mine air quality environment and real ventilation cost savings.

However, its use for mine air would involve an order of magnitude scale-up in the size of the system and the volumes of gas treated.

• Mine Air Quality and Ventilation Special projects and services include:

Rescue Halted as Mine Air Turns "Explosive"

Health and safety innovations have enhanced mine air quality, reduced energy consumption, and optimized safety through sensors to identify zones of highly stressed rock.

Current MMSL research activities include mine automation, mechanization, mine air quality and all aspects of production.

Radon in water - a potential source of radioactivity in the Eagle Point mine air - was of concern to a number of presenters.

In the future as exposure limits and concentrations of diesel particulate in mine air are reduced the RCD method may no longer be an alternative.

Both continuous monitors and grab sampling are used to measure radon progeny in the mine air, yielding the information necessary for proper control of the ventilation system.

If the leak were not stopped in a few minutes that shaft door would blow in, and the mine air would whisk through the hole in its turn.

(AP) - Massey exec tells AP that officials are testing mine air to see if it's safe to resume rescue.

She had reversed her camouflage cap so the peak stuck out behind her head, and it gave her the ga mine air of a Little League baseball player.

All units are diesel powered rubber tired machines, and later models have electronic engines to improve fuel efficiency and reduce emissions to the mine air and atmosphere.

Much testimony centered around the lack of a second exit and absence of deep mine air shafts, unsafe storage of combustibles, and a history of fires.

Prior to the second explosion at the Pike River mine air samples indicated a high presence of carbon monoxide and methane, and a low presence of oxygen.

The brattice was constructed by the desperate trapped miners attempting to stop the infiltration of blackdamp, in the hope of surviving on cleaner deep mine air until rescue.

Extensive underground tunnels lie beneath Gillies Hill; the mine adit is located in Cambusbarron and the mine air shaft is on the hill itself.

After a disk in a miner's air-sampler has been exposed to mine air for eight hours, the disk is sent to an M.S.H.A. office in Pittsburgh.

The mining group specializes in the areas of ground stability monitoring and control, mine mechanization/automation, mine air quality and ventilation, and coal mining health and safety.
