What are the two main types of mine ventilation systems?
-
Natural ventilation and mechanical ventilation.
-
Positive ventilation and negative ventilation.
-
Exhaust ventilation and supply ventilation.
-
All of the above.
D
Correct answer
Explanation
There are two main types of mine ventilation systems: natural ventilation and mechanical ventilation. Natural ventilation uses the natural forces of wind and temperature to move air through the mine. Mechanical ventilation uses fans to move air through the mine. Positive ventilation forces air into the mine, while negative ventilation exhausts air from the mine.
