Komatsu 930E water sprinklers at Los Bronces: dust control and fleet lessons for engineers Reviewed by Joe Ashwell First reported on International Mining – News 30 Second Briefing Two Komatsu 930E-3 haul trucks at Anglo American’s Los Bronces copper mine in Chile, originally slated for decommissioning, have been converted into 70,000 gallon (265,000 litre) water sprinkler trucks in a joint project with Komatsu Chile and Mega. Claimed as the first such 930E-based water trucks in Chile and globally, the units repurpose the existing 290-tonne class chassis to deliver high-volume dust suppression on haul roads. The conversion extends asset life and avoids procuring dedicated water trucks, with implications for fleet renewal and mine water management strategies. Technical Brief - Similar large-class truck conversions could standardise dust control capacity across mixed-age fleets without new unit procurement. Our Take Komatsu’s work on converting 930E units at the Los Bronces copper mine sits alongside its recent push into large-truck support infrastructure in the US (e.g. the new parts hub in Mesa, Arizona and the Surface Haulage HQ in Peoria), signalling a strategy to extend the life and versatility of its ultra-class fleet rather than focusing only on new truck sales. Within our Mining coverage, copper operations like Los Bronces feature prominently in the 2386 sustainability- and safety-tagged pieces, suggesting that dust, water and haulage risk controls are now being treated as core productivity levers at large Chilean copper mines rather than purely as compliance items. Repurposing two Komatsu 930E-3 trucks into water sprinklers at a high-altitude Chilean copper site implies a preference for modular retrofits over dedicated water trucks, which can be attractive for other Anglo American operations looking to manage dust with minimal additional capex and without expanding the mobile fleet headcount.
