Welcome!

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.

Symposium Highlights

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.

Sunday, April 28 - Half-Day Short courses

  • 08:00-12:00 | Fans and Fan Systems

    Facilitators: Livio Salvestro & Glenn Savage

    The 4 hour course content will cover:

    • Introduction to the different fan types available (centrifugal, vane axial and mixed flow).
    • Examination of performance characteristics for vane axial and mixed flow fans
    • Fundamental relationships defining geometric similarity, viscosity, Reynolds number, laminar and turbulent flow, boundary layer theory and basic aerofoil’s.
    • Detailed examination of aerofoil stall, stall cell propagation, rotating stall, surge and stall.
    • Hagen line method for evaluating fan system stability (parallel operation of fans).
    • Detailed examination of relationship between mine ventilation requirements as determined by modeling and fan performance for upcast, downcast, push/pull and underground booster fan applications.
    • overview of fan testing procedures and standards
    • Fan performance and reliability/availability considerations.
    • Vod risks for highly stressed fan rotors. Speed changes imposes fatigue stress cycles.
    • Suitability of different fan types for mine ventilation applications. Not all are equally suitable!

     

  • 13:00-17:00 | Mobile equipment power source – Impact on ventilation design

    Facilitators: Cheryl Allen, Manager Ventilation Design & Tech Support¸ Vale and
    Jozef Stachulak, Manager Strategic Vent & Diesel Research, Mirarco

    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.

  • 09:00-17:00 | Planning of Refrigeration and Ventilation of Hot Mines

    Facilitators: Andrew Branch, General Manager, BBE Projects (SA),
    Morné Beukes, Senior Consultant, BBE Consulting (SA),
    Stephen Hardcastle, Managing Director, BBE

    Mine refrigeration is no longer limited to a few exceptional areas in the world. Every continent with mines, now has operations that require refrigeration to ensure acceptable working conditions. This can be a function of climate and/or mining depth. In North America, especially Canada, as mines head to 3 km depth, there is a growing interest in mine refrigeration.

    The need for refrigeration has a fundamental impact on the overall ventilation planning and mine design. With the introduction of BEVs, or as a function of depth, the dilution of diesel exhaust emissions becomes a less dominant ventilation design criteria. However, ventilation remains an efficient medium to deliver cooling and remove heat, it is also required to maintain appropriate air speeds in the work-space.

    This short course 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 course media will be supplied on a memory stick, laptops are suggested.

    The preliminary programme will be:

    • Background, why and when do mines require refrigeration
    • Traditional primary ventilation design norms and myths debunked for genuine hot mines
    • Heat loads and cooling balances
    • Mine refrigeration machinery
    • Surface cooling installations and underground cooling installations
    • Novel cooling systems
    • Primary ventilation guidelines for hot mines

Venue

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. The turnkey packages in audio-visual, technical, presentation technologies and food and beverage mean that everything runs like clockwork.

The Palais’ main entrance is marked by the multicolored façade and borders the Place Jean-Paul-Riopelle, which features La Joute, a remarkable sculpture by the world-renowned Québec artist. It’s an ideal location for a breath of fresh air between meetings. 

Hotels

The CIM has already contracted room blocks during that period for the CIM convention which would be running concurrently and can guarantee the following rates in Canadian dollars at these hotels for single or double occupancy, including high-speed internet access. Each of these hotels has direct indoor access to the Palais des congrès and are situated within walking distance.
