Sunday, April 28 - Half-Day Short courses

  • Communicating the science of working in the heat

    Facilitator: Glen P. Kenny, Full Professor and University Research Chair, Environmental Physiology, University of Ottawa

    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.


  • Control Strategies for Curtailment of Diesel Aerosols and Gases in Underground Mines

    Facilitators: Aleksandar Bugarski, Senior Research Engineer, NIOSH Mining
    Jozef Stachulak, Manager Strategic Vent & Diesel Research, Mirarco

    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.


  • Fans and Fan Systems

    Facilitator: Kevin Lownie, Applications specialist, Howden Australia

    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!


  • 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.


  • Air Pollution Controls for Mine Ventilation Exhaust Installations

    Facilitator: Darryl Witow, Mine Ventilation Systems Lead, Hatch

    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:

    1. Causes and nature of contamination issues
    2. Prediction and modeling (including droplet modeling)
    3. Control techniques
    4. Examples and case studies

    An interactive format will be used and feedback, questions, and discussion of attendees’ personal experiences/challenges is encouraged.


Sunday, April 28 - Full-Day Short courses

  • Planning of Refrigeration and Ventilation of Hot Mines

    Facilitator: Stephen Hardcastle, Managing Director, BBE

    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:

    • 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


  • Ventilation network /fire modeling – errors and misconceptions

    Facilitators: Liming Yuan, Team Leader – Fires and Explosion Branch, NIOSH Mining
    Brian Prosser, Principal Consultant, Mine Ventilation Services

    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.
