HIGH PROFILE BELAZ electric drive trucks have been well received in Indonesia, and have proven themselves in fuel efficiency and availability against mechanical drive trucks at the same operation All round availability Paul Moore spoke to BELAZ about progress with new fleets worldwide, including Indonesia, South Africa, Poland and Morocco I ndonesia’s coal mining industry has one of the world’s largest mining truck fleets, particularly in the smaller payload classes in mechanical drive; and BELAZ, the first to bring smaller electric drive trucks to the global market, believes that they have a lot of potential in Asia. As an example, the PT Bukit Asam (Persero) owned and operated Tanjung Enim coal operation in Indonesia now has 40 units of BELAZ 75135 DC electric drive trucks with a 110 t capacity. In March 2017 the local dealer stated: “PT Pusaka Bumi Transportasi as the dealer of BELAZ brand in the Republic of Indonesia would like to express its highest satisfaction by co-operation with (the) regional dealer of OJSC BELAZ - Management Company of holding “BELAZ HOLDING” in South East Asia - BELAZIA Pte Ltd (Singapore) in terms of effective collaboration in sales and aftersales service in (the) Indonesian market. Due to high quality of (the) BELAZ equipment and professionalism of (the) service departments of PT PBT and BELAZIA Pte Ltd, 25 units of BELAZ 75135 dump trucks being operated at the coal mine site of the largest state-owned Indonesia coal producer PT Bukit Asam (Persero) Tbk located in Tanjung Emin, South Sumatra, Indonesia, have average mechanical availability over 95%.” In terms of comparing the BELAZ trucks with the 90 t mechanical drive trucks at the site, the statement also says that in the same conditions and on the same roads, the average BELAZ fuel consumption is 56 litres per hour while that of the mechanical drive truck of competitors is significantly higher. The customer has also confirmed the data. Following this letter another 48 International Mining | NOVEMBER 2017 15 BELAZ units were commissioned, bringing the fleet total to 40. At this particular minesite there are no extreme slopes and the roads are mostly flat with slopes of 5% or below, so long uphills were not the factor in the choice of electric drive in this case. The distance from pit to unloading area varies from 1-1.5 km. In terms of the Asian coal mines and any increasing use of electric trucks where traditionally, mechanical trucks dominate, Dzmitry Shershan, Director of BELAZIA states: “The most popular payload classes of dump trucks in the region are 60 and 100 short tons. That is a traditional trend which has been lasting for decades due to the location of the assembly plants of Komatsu in Indonesia and CAT in India. These equipment types are therefore well known by the local mining clients as well as their service departments. But as long as we have in our range electric trucks starting from 100 short tons capacity (60 tons in the future), our goal is to further prove the efficiency of this design, which may create a new trend in our favour in the local Asian markets as well as worldwide.” BELAZIA also states that the trucks have held up well to the wet climate in the region, as indicated by the availability figures. In total in Indonesia around 100 specialists (local and expats) are involved in the service and maintenance of the 40 BELAZ 75135 dump trucks. “All the necessary special equipment and tools were supplied directly to the mine site as well as spare parts for the second year of operation including strategic storage upfront in order to guarantee the best performance of the trucks, and the setting up of a temporary workshop for routine basic maintenance. All the time we are providing training for the local service team at the minesite, at another training centre of the end user, at BELAZ itself in Belarus, and we have organised visits for Indonesian engineers to Russia in order to transfer knowledge from other experienced users of BELAZ equipment.” Phosphate in Morocco In Morocco, OCP is well known to IM readers as one of the biggest phosphate rock miners in the world. The mining group is now using both BELAZ dozers and a 100 t water sprinkler and has additionally recently acquired 10 units of BELAZ 75180 trucks with 180 t capacity that were in the process of assembly in October 2017. Hamid Belfkira at the BELAZ Morocco dealer, Soberma told IM: “Three of the trucks are already assembled and they are in operation now. The feedback we get from OCP is that the units have a very comfortable cabin, with efficient air conditioning. A multifunctional electronic dashboard also facilitates the operation of the truck. The truck is noted for stability and reliability while being powerful and good value for money versus the competition. The trucks achieved 300 hours without any shutdowns; and OCP is also looking into equipping the trucks with autonomy.” VIST Group, BELAZ, Soberma and OCP are all working on this autonomy project. The BELAZ dozers are used in earthworks on slopes exceeding the limits allowed by dump trucks and are able to keep operating in the very high temperatures experienced that can exceed 50°C. “The BELAZ dozers are very robust and have given satisfaction and reliability.” Finally, the BELAZ water sprinkler sold through Soberma to OCP has been noted for the comfort of the air-conditioned cabin and the operator ergonomics. “It should also be stressed
