Ventilation Requirements
Ventilation Requirements
(OP)
Hi, I am just wondering about ventilation requirements in Canada. I read that you require 100cfm per diesel HP of equipment in a single circuit - but what does a single circuit mean?
I basically want to know if your total cfm entering the mine must provide for the sum of all simultaneously operating headings, or if it can be reused on each heading to provide each heading with supple used air as long as gases limits are not reached.
If it is the former case, is it in writing anywhere legitimate?

RE: Ventilation Requirements
The details and actual rules vary by province, but seek out either British Columbia or Ontario Mines Regs.
Other factors do come into play and the 100cfm / hp becomes an effective minimum.

Thanks a ton for your response.
