Purpose This study aims to examine when technical efficiency leads to firm profitability. Prior research reports mixed efficiency–performance evidence; the authors argue that this relationship is nonlinear and conditioned by firms’ ability to capture value from efficiency gains....

Quasi-Experimental Field Assessment of Haul-Road Maintenance Effects on Fuel Consumption, Cycle Time and Mechanical Loading of Open-Pit Dump Trucks

Haul-road condition in open-pit mining affects fuel consumption, transport-cycle throughput and dump-truck mechanical loading. This study conducted a quasi-experimental field assessment of local maintenance effects on severely degraded road segments. The full cycle register conta...
