Underground mine ventilation - Wikipedia

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 NOx, SO2, methane, CO2 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 mine ventilation is electricityto power the ventilation fans, which may account for one third of a typical underground mine'

How to Measure Airflow Velocity for Mining Applications

This is no exception in mining. One major concern for safety in mining is proper ventilation in the mine. Improper ventilation techniques can lead to reduced air quality underground, reduced oxygen levels, and even a build up of toxic gases. This is why it is vital to monitor and measure airflow in mine shafts, to properly control ventilation ...

Underground mining (hard rock) - Wikipedia

One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas).

Underground Mine Ventilation Technical Aspects of Mining ...

Airflow in U/G mines: mine air flows either through vent columns (also called vent ducts), which are pipes with a relatively large diameter, or through excavations, meaning tunnels and stopes. An airway may be any of these. Airflow occurs only when there is a force or pressure to drive it. (The same applies to all fluids, for example water).
