Whenever we mention "mine", "mining", "miner", many people will come up with the following pictures: For these people, you can only say that you are really OUT! If you will give you the following pictures at this time, will you think that mining will be related to them? Seeing this, some people may think that Xiao Bian is in the Arabian Nights, and the "Bumblebee" actually ran out. However, Xiaobian wants to say that "unmanned mines" and "smart mining" began to be implemented on our planet more than 10 years ago. First, the world's largest underground mine - Kiruna iron ore For the Kiruna Iron Mine, the world's largest underground mine in northern Sweden, the “unmanned mine†is no longer a new word. It has become the Kiruna iron mine like the high-grade iron ore that is here. label. At present, Kiruna Iron Mine has basically realized “unmanned intelligent miningâ€, and its smooth implementation has benefited from the following aspects: Mining flow chart 1. Reasonable and efficient mining process The pillarless sublevel caving method is adopted to facilitate large-scale and mechanized mining of the mine. 2. Advanced rock drilling equipment The stop rock is made by the Simba W469 remote-controlled rock drilling rig from Atlas, Sweden. The car is accurately positioned by laser system, and it is unmanned and can be continuously cycled for 24 hours. 3. Automated transportation equipment, remote control transportation and lifting operation Both ore shipments and upgrades have been intelligent and automated. The ore is loaded with Atlas's Toro2500E remote-controlled scraper, which uses a cable system and automatic steering function selected by remote control for unmanned driving. The belt conveyor automatically transports the ore from the crushing station to the metering device. After the shaft bucket is stopped at the designated position, the ore is automatically loaded into the bucket, and the staff presses the handle lifter to start immediately, and the bucket is lifted to the surface unloading station. After that, the bottom door of the bucket automatically opens to complete the unloading. The loading and unloading process is remote control, and then through technical transformation, the lifting system is intelligent. Second, the Chilean copper mine利特尼æ©ç‰¹ The Trinite copper mine in Chile uses Sandvik's AutoMine system, which automates the mine transportation system, including driving, loading and unloading operations. The operator can control in the surface control room, and one person can control multiple scrapers and trucks, and the scraper can be switched online to the remote waiting, automatic or remote control state without stopping. Its features include operational status and production monitoring, traffic control, navigation systems without infrastructure, and strong applicability. Remote control scraper operation At present, AutoMine system is widely used in trucks and scrapers in Canada, Finland, Chile, South Africa and Australia. Third, the global mining giant - Rio Tinto iron ore The 15 mining mines of the global mining giant, Rio Tinto, are located in the Pilbara mining area. If you are in a mining area, you can hear the roar of the machinery, but you can't see too many staff. The roar of machinery comes from the mine's intelligent machinery, while the latter is due to Rio's control center, which is more than a thousand kilometers away from Perth. 1, mine "deformation of gold just" At present, Rio Tinto has launched unmanned trucks from Komatsu Japan in four mines. This unmanned mining truck uses a coupled pulsed laser calibration guidance system in conjunction with a global satellite positioning system to guide the truck along a predetermined route. If the truck deviates from the route, the control terminal can display a warning message. In other words, trucks can automatically find directions and use laser sensors and radar to find obstacles. In recent years, the “Intelligent Train System†developed by Rio Tinto has been the world's first unmanned heavy-duty train system, which further “smart†the ore transportation system. 2, the "brain" of the mining system - remote control center More than a thousand kilometers away, the huge display shows almost all the control pages and operating status of the mine system. The console is divided into different groups such as mines, ports, train transportation, and scheduling. The operation center can not only develop production plans for the mines, but also develop transportation maps for the train system, and even clearly see the position information of each train, truck and excavator at any time. Remote control center Conclusion At present, the remote mining technology realized by some large foreign mines has included: rock drilling, charging and blasting, rock loading, transshipment, rock unloading and support, etc. The entire underground working face, except for the maintenance personnel, basically does not need the rest of the staff. . In Rio Tinto's “Future Mine†program, the remote control center can not only control each mine rig and dump truck, but also “dialogue†between each rig and truck to implement synchronous data exchange to achieve machine cooperation; Canada has also developed a vision for the realization of an unmanned mine in 2050, which will control all equipment in the mine through satellites to achieve mechanical crushing and automatic mining.
