Part 36 Mining


  • Section 546 requires the number of mine rescue teams to be related to the number of workers underground.
  • According to section 573, an employer requires approval from the Director of Inspection with responsibility for mines only when the gross weight of a rubber-tired, self-propelled machine is more than 32,000 kilograms GVW. However, the Director retains the right to request that an employer have tested and approved any rubber-tired, self-propelled machine at a mine site. Any machine approved under the Traffic Safety Act is approved for use in a mine.

  • Section 648 requires that machinery directly involved in loading an explosive is allowed to operate within eight metres of a hole being loaded with explosive. The distance has been reduced from 15 metres.
  • Section 692 requires underground storage of rescue breathing apparatus.
  • Section 693 allows employers to search workers entering an underground mine for prohibited means of ignition e.g. lighters, matches, etc.
  • Section 731 lowers allowable flammable gas concentrations to 40 percent of their lower explosive limit (LEL) from 50 percent of their LEL.
