As part of the efficiency improvement programme, the Solntsevsky coal mine, a key mining asset of the Eastern Mining Company, has introduced a modern high-speed refuelling of mining equipment. The new system allows to reduce the time for refuelling one piece of equipment by 2.5 times and increase the time of mining equipment productivity.
As part of the introduction of a high-speed refuelling system, the fuel dispensers were modernised. The throughput of the fuel was increased by increasing the diameter of the pipeline, more powerful high-performance pumps were installed, increasing the fuel supply capacity from 250 to 500 – 600 l / min. Also, the quick disconnect couplings have been improved for faster and more convenient machine maintenance. Thanks to technical updates, it was possible to achieve the required pressure in the fuel tank, which automatically closes the valve of the filling nozzle when the tank is full.
The whole range of implemented measures has reduced the time spent on replenishing the mining transport units with fuel. For example, earlier it took 15 mins. to refuel BelAZ with a carrying capacity of 220 t with a tank volume of 2150 l. The refuelling time is now 6 mins.
“We started implementing a project to develop and implement high-speed filling stations at the beginning of the year. When planning, all aspects were taken into account: from the number of fuel dispensers and their initial technical characteristics, as well as the total number of the vehicle fleet of 133 units to the number of vehicles working in one shift and the amount of fuel consumed by them. The new system allowed us not only to increase the speed of refuelling machines, but also to optimise the entire workflow, getting rid of downtime and queues. As a result, when 110 dump trucks are operating on the line, the new system of high-speed refuelling makes it possible to free up almost a day of work for 1 unit of equipment,” commented Stanislav Wegner, Technical Director of the Solntsevsky coal mine.
Within the framework of the project, a regulation has been developed that allows regulating the supply of equipment to a gas station. The refuelling process is carried out using the automated dispatching system ‘Karyer’, which monitors the amount of fuel remaining in the tanks, the location of the equipment, the load of the dispensers and makes the optimal decision on refuelling.
The commissioning of a new high-speed fuelling system made it possible to create an additional 10 new jobs in the Uglegorsk region, working in shifts to ensure round-the-clock and uninterrupted operation of the gas station.
