Equipment lifespan optimization

Compared to equipment used in hard rock mines, the lifespan of equipment deployed in oil sands operations tends to be shortened due to the abrasive nature of the material and soft ground conditions in which it operates. One of the challenges of oil sands mine planning is to determine the most cost-effective replacement time for aging equipment. For cost engineers dealing with aging equipment, the options become an economic trade-off between taking the chance of higher frame failure or buying new equipment. Therefore, the ultimate question is: “When is the best time to replace the equipment?”
