The Organizing committee of the upcoming 17th North American Mine Ventilation Symposium (NAMVS 2019) in collaboration with The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) is pleased to announce the NAMVS 2019 symposium, which will be held at the Montréal, Canada Palais des Congrès from April 28 to May 1, 2019.
The North American Mine Ventilation Symposium is organized and led by a coalition of 4 leading partners. Since the first Symposium in 1982, the Underground Ventilation Committee (UVC) has sought to provide mine ventilation engineers and technicians in the underground coal, metal, and industrial mineral mining industry with the latest information and operating practices from the field and promote the exchange of ideas and research in a variety of related areas to include the monitoring of air contaminants, determining fresh air requirements, and producing power efficient ventilation and cooling systems and energy-related topics.
The NAMVS 2019 is a peer-reviewed symposium scheduled to run for 3 days. It will be made up of full-day parallel technical streams, include 7 workshops, 16 exhibit booths, networking activities and attract a total of approximately 300 delegates.
Parallel to the NAMVS 2019 will be the CIM Annual Convention with over 400 booths. Registration options to have access to both events will be made available.
Technical program: 3 days and 2 parallel streams of up to 100 peer-reviewed papers will be presented during the symposium. Presentations will not exceed 20 minutes each.
Workshops: will precede the conference and will vary in length - from ½ day to full day. Pricing will reflect the costs involved and length of each. Potential workshop topics are outlined further.
Trade Show: 14 exhibits regrouping Ventilation sector suppliers of equipment, services and technologies will make up the place of meeting, networking and business throughout the event.
Banquet: A formal evening of great entertainment, food, fun and company will allow delegates to networks and celebrate.

Occupational heat stress is detrimental for human health and performance compromising worker productivity especially when work is performed over consecutive days. Physically demanding work in the heat causes next-day effects (fatigue, fluid depletion, others), that increase a worker’s risk of heat-related illness. Traditionally, environmental and clothing parameters and the estimated rate of metabolic heat production are used to quantify the level of heat stress and determine practices such as work/rest schedules, work tolerance time, and others to prevent excessive heat strain in workers; a response typically defined by a threshold-core-temperature or exposure-time. However, recent work demonstrates that these guidelines do not adequately protect workers. This is primarily due to the fact that commonly employed heat-management strategies fail to consider inter-individual factors such as age, sex, anthropometrics, fitness, health status (others) as well as intra-individual factors (consecutive works shifts, shift duration, hydration status, other) that can affect an individual’s capacity to dissipate heat. In this workshop, we discuss breakthroughs in the development of heat management strategies as well as fluid intake guidelines, which consider these factors. We explore the application of heat-strain-reduction solutions that relies upon physiological monitoring to ensure workers are provided with individualized and real-time protection from excessive heat strain.

The course will provide lectures and forum for discussion on various topic related to the ongoing efforts of underground mining industry to reduce risks associated with exposure of workers to particulate matter and gases emitted by diesel-powered equipment. The workshop will provide overviews of: (1) issues related to the exposure of underground miners to diesel aerosols and gases, (2) methods used to measure diesel emissions and monitor exposures of underground miners to diesel aerosols, (3) control strategies and technologies available to underground mining industry to curtail particulate matter and gaseous emissions such as repowering existing engines with advanced low-emitting engines, retrofitting existing engines with exhaust aftertreatment devices, substituting diesel-powered vehicles with electric-powered vehicles, and substituting petroleum based fuels with alternative fuels such as fatty acid methyl ester (FAME) biodiesel and hydrotreated vegetable oil renewable diesel (HVORD), and (4) alternative control strategies and technologies that underground mining industry might deploy to reduce workers exposures to diesel aerosols and gases such as enclosing workers in the environmental enclosures with adequate filtration and pressurization systems and using adequate personal protective equipment (PPE). The course would provide insight into the ongoing pertinent research and implementation projects and trends in the U.S. and Canada.

Mobile mining equipment powered by the diesel engine has proven very valuable and flexible in its use; however, it also has a disadvantage of emitting heat, gaseous substances and diesel particulate matter (DPM). The World Health Organization has confirmed that diesel emissions are a known carcinogen resulting in regulations allowing less exposure to contaminants. The requirement to curtail emissions and at the same time realizing a substantial increase in the cost of power and fuel; there is incentive to replace the diesel engine with an alternative power source such as a battery motor. Ventilation systems are necessary to dilute and remove contaminants from the mine; however, they are both capital and operating cost intensive, with a typical base metal Canadian mine ventilation system consuming between 50%-80% of the site’s power demand. Reducing the airflow into a mine will result in a significant drop in power consumption; therefore, the alternative of mine designs employing battery/electric equipment as well as new mine project feasibility studies are underway.
This workshop will discuss ventilation design and the impact when diesel powered equipment is replaced and/or integrated with battery powered equipment in stages or in full.

Water droplets transported in mine exhaust can damage fans and have a detrimental impact on the local environment. Thus, controlling the transport of water droplets in mine exhaust systems can lead to cost savings in fan performance and maintenance as well environmental benefits.
The workshop will cover four areas:
An interactive format will be used and feedback, questions, and discussion of attendees’ personal experiences/challenges is encouraged.

Mine refrigeration is no longer limited to a few exceptional areas in the world and mines in many different countries are at horizons where refrigeration is required to ensure acceptable working conditions. There is a growing interest in mine refrigeration in North American mines.
The need for refrigeration has a fundamental impact on the overall ventilation planning. For example, diesel emissions [apart perhaps diesel heat] are no longer one of the dominant ventilation design criteria and neither are the work-space air speeds [although basic minima must be upheld].
This workshop will cover the basic cooling-heat energy balance which leads to a hierarchy of best cooling strategies as related to depth in different mining areas. The workshop will examine the different cooling generation and distribution options. This will be supplemented by numerous case studies through real, implemented large mine cooling and ventilating systems from around the world [with a large amount of photographic material].
The preliminary programme will be:

This course will present the basics of mine fire modeling, incorporating the latest developments using MFIRE, the PMRD (Pittsburgh Mining Research Division) mine fire simulation software. PMRD will cover fire modeling application issues including accurate identification of the fire source, establishing input parameters for fire simulation, and correct interpretation of the simulation results. A review of possible errors and misinterpretation of results will be presented. PMRD presenters will also discuss integration of atmospheric monitoring system data into MFIRE to improve the fire modeling results.
Examples will be presented that will identify the variable nature of the analysis based on the input parameters and a design process will be presented to help ensure the adequacy of the modeling effort. The proper use of fire modeling studies and their place in ventilation design will be discussed.
The Symposium parallel rooms will take place at the versatile and ultramodern Palais des congrès de Montréal. An ideal venue for meetings, trade shows or special events, this state-of-the-art facility is strategically located between Old Montréal and downtown, just north of Autoroute Ville-Marie.
