The atmosphere in a mine can be volatile, which is why mining breathing equipment is so important. Despite the greatest safety precautions being undertaken by mine operators and workers, breathable air can become compromised in seconds. Maintaining a proper ventilation system is vital for worker safety, but it's still important to have emergency breathing apparatus Continue reading Self

Apparatus within the scope of this standard may also be subjected to additional requirements in other standards – for example, IEC 60079-0. The ignition protection is based on the limitation of the maximum surface temperature of the enclosure and on other surfaces which could be in contact with dust and on the restriction of dust ingress into the enclosure by the use of dust-tight or dust

US Patent for Pumpable product hydraulic mining

The present invention relates to a feeder-breaker apparatus and method for use in the hydraulic mining of friable materials such as coal, tar sands and uranium. It is particularly directed to such an apparatus and method wherein the mined product is reduced to a pumpable form so that it may be pumped under pressure without dependence upon gravity for its conveyance.

Windows in flameproof apparatus, such as those needed for reading instruments, are flat plates of toughened or annealed glass not less than 1/4″ inch thick. They are usually cemented into a form which makes a flameproof joint with the wall, so that the glass itself makes a flameproof joint, being secured by a metal retaining ring screwed to the inner surface of the enclosure.
