There is considerable crossover in terms of technologies and mining methods used in Canada and in Africa. Global African countries share with Canada the common predominant usage of bulk emulsion explosives, and these markets have all seen a high conversion to electronic detonators as part of their production regime. In the underground space, there has been a push within the Canadian market to convert mining development and stoping to bulk explosives, to replace bagged Anfo and cartridges for both regulatory and productivity reasons. The growing concerns over the issue of nitrates in groundwater, for instance, have led to mining companies moving to emulsion options in which the nitrates in the explosives are not water-soluble. In fact, many of the mining regulations in place on the South African law books were informed by those in Canada — from where much inspiration was drawn in the 1990s and which later would guide South Africa’s policy frameworks. Mines in African countries and in Canada have similar expectations of their explosives providers, looking to them for an extensive range of services; the two high-level services — rock-on-ground and down-the-hole services — are quite comparable between these markets. The way that mines make use of contractors is also quite similar between these markets, with mines often outsourcing mine construction and development work to contractors, while conducting in-house the core and critical activities like ongoing blasting and mining. b FEBRUARY 2018 MINING MIRROR [9]
