Open fire in a mine gallery causes large-scale damage to property and sometimes precious lives. Such fires produce two distinct effects, the throttle effect and the buoyancy effect. These effects disturb the ventilation system of the mine. To understand the complex dynamic phenomenon of open fire and its effect on ventilation systems, a mine fire...

Chapter 1: Mine Ventilation – An Overview Page 2 Revolution, the working of seams rich in methane gas, inadequate ventilation, furnaces located in methane-laden return air and the open flames of candles. There are many graphic descriptions of methane and coal dust explosions, the suffering of mining communities, the heroism of rescue at-
A new smart ventilation system now recognizes the location of people and vehicles in the mine and delivers fresh air on demand, increasing safety and maximizing efficiency Services Round-the-clock remote monitoring services provide access to real time data about mission-critical equipment.
Underground mines can present a radiation hazard to miners. Without proper air ventilation, radon can collect in the mineshafts, where it is inhaled by miners. The operators of uranium mines must take special precautions to protect miners, such as pumping radon gas out of the mine .

The greatest classical paper on mine ventilation was one entitled "On the Theory of the Ventilation of Mines", presented by John Job Atkinson to the North of England Institute of Mining Engineers in December, 1854.During Atkinson's productive years the first power driven ventilators began to appear.
A total mill ventilation system can lower mill-wide dust concentrations, hence reducing respirable dust exposures of workers in mineral processing operations. The system uses clean air drawn in at the base of the building to dilute and remove dust from contaminated areas within the mill structure.
The regulatory document pertains to any ventilation of uranium mines and mills for the purpose of assuring the radiation safety of workers and onsite personnel. This ventilation may be associated with any underground or surface area or premise that is licensable by the CNSC as part of a uranium mine or mill. These areas and premises typically ...

It is usually said that mining in the area ceased because the mines "played out". What makes that interesting is the fact that lead and zinc were found at least as far south as Spavinaw!
The tunnel would provide water drainage, ventilation and economical transportation of the gold bearing ore from the many mines it would intersect along the way. The Argo Mill was constructed to process the gold bearing ore from these mines. When completed, the Argo would be the largest mill .
The Britannia Mines Concentrator is a National Historic Site of Canada. The large, inclined gravity mill was built on the northwest side of Mount Sheer to assist the transfer of copper ore through the chemical and mechanical processes of the plant. It is a landmark in Britannia Beach, British Columbia some forty-five kilometers north of Vancouver.
