"New employees" come to the mining area: technology enables zero-carbon mines
2023-01-30
During the Spring Festival, Jungar Banner Economic Development Zone, Inner Mongolia. When night fell, the lights in the R&D building of Inner Mongolia Tiechen Intelligent Equipment Co., Ltd. lit up early. Wang Xinggang, director of the R&D Center, was leading the team to work overtime to promote the key projects. "R&D should always be on the way, achieving results one day earlier, getting twice the result with half the effort; and the track one day later, getting twice the result with half the effort." This concept has penetrated into the hearts of every member. A year ago, the company launched its first 95-ton pure electric driverless mining vehicle, marking that it has achieved a "win-win" of driverless and new energy. In the endless mine of Jungar Banner, giant trucks loaded with coal shuttle through it, but there is no roar of the engine and black exhaust of the past. When approaching, people will be surprised to find that the cab of the walking truck is empty. As the county with the largest coal output in the country, Jungar Banner, while providing solid energy security for all parts of the country, is also practicing the green and intelligent development concept by virtue of technological innovation. From engineer following test, to safety officer following operation, to today's safety officer getting off the train and mining car driving independently, mining car driverless technology has been developed rapidly in Jungar Banner, and the scientific research team of high-tech enterprises has contributed a lot. In the workshop of Tiechen Intelligent Equipment Co., Ltd., the sound of mechanical operation keeps coming and going, the parts and components of automobile production line are lined up in order, and the full-automatic flow production line is fully powered. According to the person in charge of the enterprise, more than 100 orders from open-pit coal mines in and around the city have been put off the production line. In 2023, they ushered in a "good start" for development. The application of driverless technology is not smooth, and difficulties come one after another in the process of research and development. "There are practical difficulties in unmanned driving in open-pit mines, such as no obvious road signs, weak communication satellite signal coverage, and large positioning error. We will tackle these bottlenecks one by one," Wang Xinggang told reporters. Through the efforts of the research and development team, the latest off-line driverless mining vehicle adopts the vehicle wire control technology, which can accurately and smoothly complete the projects of reversing, parking, and autonomous obstacle avoidance at the mine site. At the same time, the vehicle is equipped with environmental awareness system, behavior control, positioning system and high-precision map, which can complete the automatic loading, transportation and unloading cycle operation under the condition of unmanned operation according to the mine dispatching instructions, and achieve the goal of low cost and high efficiency of mining operations. Wang Xinggang pointed to the design drawing on the computer and introduced to the reporter: "At first, we took driverless mining vehicles as our main production goal. After the launch of the 'double carbon' strategic goal, we turned in time and directly entered the new track. Through cooperation with colleges and universities of well-known domestic research and development institutions, we carried out the research and development of pure electric, hydrogen and other new energy mining vehicles. At present, we have successfully mastered core technologies such as MCU motor controller, BMS high-voltage battery management system, VCU vehicle controller, etc. After the Spring Festival, we will There are 20 105-ton new energy pure electric mining vehicles offline. " Wang Xinggang said that half of the cost of traditional fuel wide-body mining cars comes from fuel consumption, and the energy consumption cost of each car is about 570000 yuan. If it is replaced with pure electric new energy mine card, the energy consumption cost will be reduced to 260000 yuan. From the perspective of carbon emissions, fuel vehicles
