MineARC recently travelled to the province of Quang Ninh, to meet with key personnel at various mining companies, including Vietnam’s largest mining conglomerate, Vinacomin.
Our team was fortunate to be granted the opportunity to visit a number of sites and were invited underground at both the Mao Khe and Ha Lam Coal Mines; gaining invaluable insights into the operations and requirements of the Vietnamese mining industry.
These large-scale mines see up to 1200 personnel working underground during each eight-hour shift, often in incredibly deep, hazardous conditions. Attitudes towards health and safety within these sites are shifting, with a stronger emphasis on creating better working environments for miners.
Coal Mine Refuge Chamber
The MineARC CoalSAFE was extremely well received during our visits; many sites indicating strong interest. Developed specifically for underground coal mining conditions and blast proof up to 15 psi overpressure, the CoalSAFE can withstand primary and secondary explosions, extreme temperatures and flash fires. Innovative in design, it is currently the only refuge range on the market to incorporate both a powerless carbon dioxide/carbon monoxide scrubber, as well as an intrinsically safe air conditioning system (refrigerant R744).
Additional features of the CoalSAFE include; a flushing airlock, explosion proof viewing portals, internal and external gas monitoring, and communication ports. Options available to allow for up to 100 hrs safe refuge.
EnviroLAV Toilet for Mining
The MineARC EnviroLAV Toilet System, an award-winning underground waste management unit, also proved to be a popular product during the visit. With many mines across Vietnam suffering the impact of poor ventilation and waste disposal, the EnviroLAV’s innovative design generated a lot of interest.
Drawing on existing biological technologies currently used in two different forms of waste management, the system utilises both aerobic and anaerobic reactions to break down matter. Within the EnviroLAV’s sterile, biological treatment tank, micro-aeration filters continually work to break down effluent, aided by MineARC’s unique EnviroZYME solution. As a result, the EnviroLAV requires emptying just once every 12 months.
This process of organic waste management results in decreased environmental impact, lower maintenance requirements and a more sanitary working environment.
