THE ELECTRIC MINE WORKING GROUP

This working group is a global community that aims to accelerate the adoption of all-electric technologies in mining, address the challenges associated with them, and share information on how they can enable safer, more efficient, productive, and cost-effective mines.

OBJECTIVES

  • Accelerate the advancement and adoption of electric mining technologies in underground and surface contexts by sharing data, best practices, models, and cross-learning.
  • Enable a global community of practice that includes operators, suppliers, subject matter experts, and leaders from inside and outside the industry to drive valuable conversations, share lived examples, and find collaborative solutions to key challenges.
  • Oversee projects that deliver high-quality information and guidance on electric mining technologies and designing electric mines

 

KEY TOPICS

  • Potential risks and safety considerations associated with electric equipment such as fire safety
  • Battery management
  • Designing electric mines
  • Equipment monitoring
  • Analyzing electric equipment based on performance, cost, and requirements
  • Emerging non-diesel technologies

 

WHY ELECTRIC MINES MATTER

The mining industry relies on fossil fuels, namely diesel, to drive business. However, they are expensive and limited resources and have been proven to pose health hazards.  For example, diesel emissions are classified as ‘Group 1: carcinogenic to humans’ by the World Health Organization.

Electric mining technologies offer multiple advantages:

  • A safer work environment
  • Reduced energy costs
  • Minimized environmental impacts
  • Enhanced productivity, efficiency, and performance

While there are many benefits, there are also multiple challenges that come with them, including energy consumption modelling, operational and infrastructure adaptations, and change management.

ACTIVE PROJECTS

Electric Mobile Equipment KPIs and Definitions

This project aims to develop common key performance indicators to help enable mine operators to identify equipment performance and benchmark against other mine operations with the goal of improved electric equipment performance. It is currently in content generation. Learn more

Implementation of Battery Electric Vehicles in Surface Mining

Surface mining faces additional challenges when implementing electric equipment compared to underground mining, including finding the right size of the equipment and storage hazards related to weather conditions. Since size, weight, and cost are key challenges for surface mining, adapting mine operations to match availability of battery electric vehicles will be important when planning a strategy.

2020 June | Electric Mine Operational Knowledge Sharing Platform Summary of Survey Results and Workshop Outcomes

A survey that was open between April and June 2020 with 95 respondents (as of June 9) and workshops held on May 7 and May 20 aimed to define priorities for the GMG Electric Mine Operational Knowledge Sharing Platform project. This project aims to create a neutral platform to capture performance data for electric surface and underground equipment based on the industry’s knowledge and experience. Click here to read.

KNOWLEDGE SHARING PRESENTATIONS

Battery Electric Vehicles in Mining Version 3 (Video)

The Battery electric vehicles (BEVs) have seen many advancements in the past two years. Further, there is a continued urgency around reducing greenhouse gases and a growing industry interest in adopting battery electric technologies, in both the underground and surface communities. Advancements such as the greater variety of battery chemistries on the market, changing ventilation requirements and varied charging philosophies need to be captured and recorded based on real operating experiences. The project aims to update the previous version of the guideline leveraging lessons learned, particularly related to safety and maintenance, and accommodating technology advancements. It will also add information to provide valuable guidance to the surface mining community. Click here to watch.
