Xinjiang is the largest provincial-level administrative region in China. Under the vast desert, there is an extremely rich sea of coal. Some of the coal transported from here will be transported to other places with trucks and trains, and some will be converted into electricity in nearby power plants and then delivered to thousands of households. If you look down from an aerial perspective, there is an unreal industrial aesthetic here. The mine with layers of operations is like a big sand table. There are several small worlds among them, and nearly 50 unmanned mining trucks of Yikong Zhijia are busy here.

The normal operation of unmanned multi-vehicles will add another 100 units to the mining area

Yikong Zhijia first started the unmanned driving test in a small coal mine in Ordos, Inner Mongolia. In the initial stage, there were only 3 or 4 vehicles, mainly for the testing and polishing of single-vehicle operations, so that the unmanned driving system can realize "mining and transportation platooning" Operation. In 2020, when we came to the mining area to start operating tests, the team initially figured out some basic rules, but at that time it was mainly based on single-group operations.

The second stage is to enter the National Energy Group Zhundong Open-pit Coal Mine and TBEA Xinjiang Tianchi Energy South Open-pit Coal Mine to start real operations, and successively expand the operating fleet to two teams, four teams, and then to the current six teams. After multiple marshalling, on-site management intervention is required, and excavator layout and operation should be considered. This also means that the original operating logic based on single-group development needs to be continuously iteratively developed and a balanced scheduling strategy should be made. Unmanned driving in mines is transformed into data by collecting on-site operation experience, and then drives the algorithm to continuously iteratively upgrade, and these engineering data will also be solidified through the accumulation of operating standards.

In the next stage, Yikong Zhijia will put another 100 unmanned mining trucks into the South Open Pit Coal Mine, which will be the first in the world to carry out the commercial batch application of more than 100 unmanned mining trucks in a single mine. In addition, due to the fact that Yikong Zhijia has accelerated the change in the operation of the flat plate and the dump site in the actual operation process, and at the same time realized the normal unmanned continuous operation in the outer dump site with higher technical requirements, the mine also The internal dump site that is more closely integrated with production will be entrusted to Yikong Zhijia for construction. The development of internal dumps means that the unmanned transportation capacity has been further recognized. In the process, traditional mining, unmanned technology and vehicle technology have been deeply integrated.

Go deep into the front-line scene of the mining area, "improving quality and efficiency" and "energy saving and emission reduction" simultaneously

In order to accelerate the application layout of artificial intelligence technology in smart mining scenarios, represented by autonomous driving talents, vehicle engineering talents and mining technology experts, the employees of Yikong Zhijia gathered together to actively open up each other's knowledge systems and collide with each other , integration, and polished a set of operation services and technical solutions dedicated to unmanned driving in mines. The standardization and process of mine operation requirements will also penetrate into all aspects of daily work. It is as big as attending the morning shift meeting and evening shift meeting every day, as small as which side to park the vehicle on, and the orientation of the front of the car has clear requirements.
Yikong Zhijia also pays attention to improving quality and efficiency in actual operation. In order to ensure that the vehicle achieves optimal efficiency and cost under safe conditions, the efficiency will be improved through various scheduling modes, global balanced vehicle allocation, and more refined processing of collaborative operations between devices, so as to achieve the highest operating efficiency of the road network. maximize. In terms of specific single-day working hours, unmanned driving can achieve 20-21 hours, which is about 2 hours higher than the average operation time of traditional manned driving.

In terms of energy saving and emission reduction, Yikong Zhijia is actually using green and intelligent technology to meet the requirements of improving efficiency and expanding production capacity in mining areas. For example, in the Bailifu Mountain Aggregate Mine in Honghe, Shandong Province, 40 unmanned pure electric mining vehicles have been deployed. In the first phase, 20 vehicles have realized the normal operation of multiple marshalling vehicles, with full coverage of 5G signals and photovoltaic solar power generation. , and cooperate with partners to build China's first digital, intelligent and unmanned zero-carbon mine. According to Yikong Zhijia, the use of pure electric vehicles can greatly reduce the emission pollution caused by diesel-powered vehicles when they are used as the main means of transportation in scenes with many heavy-duty downhill conditions such as sand and gravel aggregate open-pit mines. , making the mining industry a real "low-carbon species".

Practice the concept of green development Create social value with the power of science and technology

On November 5, 2021, the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Natural Resources jointly issued the "Implementation Plan for the "14th Five-Year Plan" for Promoting the High-quality Development of Resource-Based Areas" and pointed out: "Vigorously promote the construction of green mines" and "support resources Low-carbon, green, intelligent technological transformation and transformation and upgrading of large-scale enterprises, coordinate and orderly do a good job in carbon neutralization of carbon peaks.
While constantly improving its own intelligent transportation capabilities, Yikong Zhijia is also actively practicing the concept of green development in mines, such as: building intelligent energy replenishment facilities in mining areas, so as to dynamically control the energy replenishment business of new energy mining trucks; applying photovoltaic green Electricity, a new energy mine application scenario that realizes zero-carbon energy replenishment; self-defined 100-ton new energy unmanned mining trucks, with extended range, pure electricity, fuel cells and other energy types, to meet the needs of charging, battery swapping, refueling, etc. Hydrogen and other forms of supplementary energy; through the control strategy of the wire-control chassis and the control algorithm of unmanned driving, the energy consumption of standard working conditions can be reduced, and the maximum fuel saving rate can reach 30%.
