classification of the mine ventilation equipment

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.

Ventilation Basic Mining Process/Terminology

Ventilation. Good quality air has to be provided for personnel to breath, to dilute both natural and introduced (e.g. diesel exhaust) gases, to dilute or carry away dust and to provide cooling for personnel and machinery. A small quantity of air may flow through mine workings naturally but this would be insufficient and uncontrolled and

Guidance about underground air quality and ventilation

Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub-standard (or even dangerous) condition if contaminants (e.g. gases, dusts, fumes) produced in the course of operations are not

Miners Anemometer | Hand Held Meter for Mining Industry

In addition to utilizing a mining anemometer to measure air flow, mine managers also employ tracer gas, to measure the resistance of individual airways in a mine, an aneroid barometer to determine pressure loss, and mine ventilation simulations to help select ventilation equipment.

Electrical equipment in hazardous areas Wikipedia

In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations could provide an ignition source, due to electrical arcing, or high temperature.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
