What is Underground Mining? (with pictures)

One major need with underground mining is ventilation. Ventilation is necessary to remove dust, byproducts of combustion, and byproducts of explosions, along with gases which may be trapped in pockets inside the Earth.

ESTABLISHING TOTAL AIRFLOW REQUIREMENTS FOR

2013-8-20 · Traditionally, airflow requirements for diesel equipment operating in underground environments such as mines and tunnels were determined by multiplying the vehicle power by a ventilation rate that was either mandated by regulations(s) or determined empirically from known quantities. In some cases, utilization factors were further used to adjust (reduce) the total airflow calculations for a diesel equipment fleet. However, in light of the drastic reductions to diesel equipment emissions mandated by the US EPA Tier IV and EURO Stage 4 regulations, there is currently a great deal of uncertainty in the underground mining industry among those responsible for the ventilation of planned new mines or the expansion of current mines. Tier IV engine standards mandate a reduction of DPM and NOx of approximately 95%, but can ventilation rates at mines
