Published: October, 2018

Submission: October, 2018


Earlier this year, the Minister of Mineral Resources (the “minister”) published a notice amending Chapter 4 of the regulations relating to explosives, binding in terms of the Mine Health and Safety Act, 1996. The regulations will come into effect at the end of the 2018 year.

Important changes in the amended regulations include:

  • that an employer of an underground mine may, by means of a risk assessment conducted in consultation with the explosives manufacturer or supplier, determine a safe distance to which explosives may be brought to a working face where the drilling of shot holes is not complete (Regulation 4.6(3)(a)(iv)); and
  • employers at both underground and surface mines are required to facilitate that (as per Regulations 4.6(3)(b), 4.6(5)(c) and Regulation 4.14):
    • stemming and tamping is performed between the explosive charge and the collar of the shot hole
      • with a material determined in consultation with the explosives manufacturer/supplier and stemming manufacturer/supplier; and
      • with the length of the stemming and tamping material determinable by means of risk assessment.
