This project is a partnership between GMSG and CMIC

 

Project

The purpose of this project is to develop a global guideline for use of battery electric vehicles (BEVs) in an underground mining environment.  The main objectives of the guideline are:

  • To be structured in such a way that the guideline can act as a specification, and be included by mining companies in tender documents to equipment OEMs for mining vehicles.
  • To act as a guideline / blueprint / path forward for vehicle OEMs. It will allow the OEMs to focus their R&D efforts in a particular direction.
  • Strike an appropriate balance between standardization and innovation. The guideline should allow miners to operate a fleet of BEVs without concerns about proprietary equipment and interfaces.  At the same time, the guideline should not be an impediment to innovation for OEMs.
  • Leverage existing standards, including those from the automotive, electrical, automation and any other industries that may apply. Favour the referencing of existing standards/guidelines.
  • Be global in scope, but friendly to regional differences. Mining companies and OEMs throughout the world should be able to use the guideline, however it should acknowledge that regional differences in standards and regulatory framework exist.
  • Use simple, straightforward and direct language.

 

Case

The mining industry is now extracting mineral reserves at greater depths. As underground mining progresses to deeper levels, ventilation for a diesel mobile equipment fleet is becoming more of a challenge.

Battery electric mobile equipment offers a unique opportunity to drastically reduce the ventilation requirements for a mine. At the same time, it can reduce operating costs and improve the environmental footprint. However, battery electric vehicles (BEVs) also present a new set of challenges for mine operators in terms of infrastructure requirements, maintenance and operating constraints:

 

Charging:

  • Required mine infrastructure for charging of BEVs.
  • Charging methodology – On board, off board or battery swapping.
  • Charging interface standardization (connection and protocol between vehicle and charger).

 

Equipment Standards and Legislation:

  • Lack of mining-specific standardization.
  • Existing standards and legislation are geared toward diesel equipment
  • Differences between jurisdiction / region.

 

Mine Operation:

  • Limitations with BEV energy density vs Diesel.
  • Mine Layout considerations

 

Objective

To publish and maintain a global guideline for use of battery electric mobile mining equipment in an underground mining environment.
