What are risks associated with mining?
Because flammable chemicals and gases are often running through pipes in an underground mine, it will be important that the ventilation systems are periodically checked, and warning signs are posted to remind workers of safe practices. → Cave-ins, collapses, or rock falls: The infrastructure of mines can sometimes result in catastrophe.

Guidance about underground air quality and ventilation
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 controlled, safely extracted or diluted to acceptable levels. Ventilation is used to extract and dilute contaminants.
