Chapter 8. Mine Ventilation Thermodynamics

Hinsley (1900-1988) into the realization that a mine ventilation system is, indeed, a gigantic heat engine. Air enters the system and is compressed and heated by gravitational energy as it descends in downcasting shafts or slopes. More heat is added to the air from the strata, machines and other sources.

Mining Ventilation Consultants SRK Consulting

Using innovative fire, air cooling, and ventilation modeling software developed in house, we establish reliable, safe and efficient underground ventilation systems that control airflow, pressure, and climate. Our consultants specialize in tackling challenges posed by demanding climatic or geologic conditions.

High Pressure Ventilation Mine Doors Hoffman Manufacturing

High Pressure Door Systems. Most mines work on a partitioned ventilation system. In a partitioned system, different areas are sealed off from one another, meaning that risks such as noxious gas buildup can be localized. This helps minimize risk and maximize control throughout the entire mining area.
