About MVS

Mine Ventilation Services (MVS) was founded in March 1983 in response to a growing demand for specialized expertise in the design, planning and control of the environment in underground openings.  Our staff has extensive experience in all aspects of ventilation and air conditioning design, including the installation and calibration of ventilation monitoring equipment.
MVS consists of a select team of mine ventilation engineers, mining engineers, research scientists and computer software engineers who are experienced in the theoretical and practical aspects of heat transfer and ventilation and air cooling computer modeling.
MVS is a professional engineering consulting firm with experience in a number of countries. We specialize in solving ventilation and cooling problems associated with the operation of mines and other subsurface facilities, including those which pose special challenges due to unusual climatic or geologic conditions.  MVS is experienced in designing ventilation and cooling systems for new and proposed subsurface facilities.  We begin with conceptual studies to identify the most feasible overall plan.  We then conduct detailed engineering studies using in-house computer software programs which have been developed specifically for the purpose of projecting optimal duties and locations of fans, cooling plants, main shafts and airways.  The fan duties, and where required cooling and air filtration duties, are projected along with operating and capital costs.  We have developed a wide range of software programs which have proven invaluable in designing ventilation systems for underground facilities.
At MVS we believe that in order to develop safe, cost-effective ventilation and air conditioning systems we must keep up to date on the latest technologies.  We are pleased to have contributed to the industry's technological achievements and welcome projects that have a strong research component.
MVS has also developed a Diesel Particulate Matter (DPM) analysis laboratory.  MVS now has the capability to analyze DPM filter samples and institute sampling programs at mining operations.
