MAINTENANCE EFFICIENCY IS KEY TO MINING OPERATION PRODUCTIVITY Everything is a numbers game in the mining industry,especially when maintaining the fine balance between expense and time. Running lean requires operational efficiency reliant on a defined service schedule for vehicles that eliminates downtime and maintains vehicle productivity. To better contextualize how granular mining operations can be tracked, let’s take the example of an average open-pit goldmine with a 2 g/t Au grade. There is a reason that they call equipment at mine sites “earth movers” and not “gold movers” as 90,000,000 grams of earth yields around 180 grams of gold after extraction. To move as much ore as possible, our hypothetical mine likely has around 60 haul trucks and 4 excavators with hydraulic shovels to move material. This excludes additional working equipment like dozers, loaders, graders and drilling rigs that make the final transport happen. Each shovel loads 15 trucks with 4 full buckets each. On a decent loading surface, a good operator can fill a bucket, dump it into a truck and get back to the face in 30 seconds, which brings us to 2 minutes per truck and 1 minute between the trucks to drive at the spot. One full loading cycle of 15 haul trucks then will take around 45 minutes, and the drive to a dump area should be less than 45 minutes for a shovel to run without downtime. Shovels need to be kept in service to increase efficiency; the downtime cost of these shovels can be around $60,000/hour and the downtime of a haul truck around $3,000. To increase the equipment availability rate (the ratio of equipment in service to the total number of equipment on site), mining companies use the following tools: SERVICE TRUCKS A workshop on wheels, service trucks primarily serve the bigger shovels and excavators at a mine site. With the cost of machine downtime at so high a premium, these trucks are equipped todeliver high volumes of grease and increased flow rates of oil. These services minimize the service time of bottleneck machinery on site and help to optimize operational efficiencies. LUBE PIT STOPS While not quite hitting the speeds of the vehicles on a NASCAR or Formula 1 track, haul trucks come to a pit stop located at an open-pit at the site to make oil top-ups, refill grease reservoir, fuel up, and receive overall equipment inspections. Fluid management solutions play a crucial role in ensuring oil and lubricants are properly tracked. MOBILE LUBE CONTAINERS Much like a mobile triage might be set up for medical emergencies, mobile lube containers act like workshop islands around the open pit for quick maintenance solutions. Equipped to service a wide range of machinery, the pumps aboard mobile lube containers support varying lubricants and dispensing requirements. MINING WORKSHOPS The largest facility for mining maintenance operations, the main mining workshop has expanded capacity to fit larger haul trucks and other equipment inside for more thorough maintenancethan is done out in the field. While most machines have planned maintenance that might require a trip to the workshop, the purpose of service trucks, pit-stops and mobile lube containers is to ensure machines enter the bays as infrequently as possible. Using the right equipment in all maintenance-related tasks is very important. The equipment you choose to use in your mining operation could help provide faster maintenance, which will help eliminate the hours of downtime your equipment has, bringing in more gold to your processing facilities. Graco has you covered, producing a wide range of lubrication related products for regular maintenance and for the on-vehicle automatic lubrication systems.
