HIGH PROFILE
trolley cars will also allow the use of diesel engines of lower power rating . There are two different projects being developed by BELAZ specialists in this direction plus an all electric battery truck : xn Diesel-trolley truck : mining dump truck that uses an external source of electricity as power supply on a certain section of open-pit mine haul road , thereby increasing the speed of the vehicle and diesel fuel savings xn Electric trolley truck : mining dump truck that uses an external source of energy from trolley power lines and switches to on-board batteries at loading and dumping areas . xn All-electric truck : electric dump truck using traction accumulator battery pack as a power source Development of the first two types of trolley mining dump trucks is already in full swing . For equipment testing and adjustment a contact trolley line with a total length of more than half a kilometre was installed at the Zhodino factory testing grounds with a traction electric substation . The first diesel trolley truck BELAZ-7530E with payload capacity of 220 t was assembled , and a control system was developed .
Also , in 2021 , BELAZ specialists released a completely new type of all electric open-pit mining truck powered by BELAZ-7558E batteries with a carrying capacity of 90 t . This development opens a new direction in the production of " green " dump trucks completely free from harmful emissions . The use of electric dump trucks will allow mining enterprises to save money due to the difference in prices for fuel and electricity , service costs and fuel and lubricants . The battery-powered engine provides the best cost of transportation of minerals and a high level of ecology in the field .
According to preliminary estimates , savings when using a battery-powered vehicle compared to a serial BELAZ dump truck for 10 years can range from $ 1 million to 3 million US dollars ( depending on the region of operation ).
Intelligent mines
The rapid development of electronics and IT related technologies has affected all areas of activity , including mining and mechanical engineering . Thanks to this , BELAZ continues work on the development of a unified monitoring system , analysis of predictive analytics and dispatching data , united into a unified intelligent mining transport management system .
With the help of this system , the management of the mining enterprise , service services in real time receive complete information about the work of the mine . The technology is even more effective when managing a fleet of robotic equipment . In this case , the number of people involved in the work is reduced to a minimum , and the main mining
activity is performed by the smart mine system . In 2021 , tests of the robotic industrial complex of BELAZ were conducted , including robotic mining dump trucks BELAZ-7558R with a carrying capacity of 90 t and a front loader with a remote control system BELAZ-7825D with a bucket volume of 12 cubic metres . This was done as part of an intelligent quarry system , implemented in a section of Granit ’ s Sitnitskoye quarry in Belarus .
Today , for the operation of an intelligent mine system at Sitnitskoye , a modern relocatable control and dispatching centre has been erected , and a new comms network and electrical infrastructure have been installed , including 48 poles for which more than 4 km of cables were laid . The equipment that provides 5G network coverage of the mine site for controlling a robotic mining complex was mounted on 3 poles . BELAZ specialists carried out testing and debugging of the server and network equipment for collecting , accumulating and transmitting data . A video surveillance and access control system has also been deployed on the premises . IM
