4.1 Unmanned mining technology Unmanned mining technology, in terms of current metal mines, can be said to be a technology that is being formed. Although it has been widely used in mineral processing , most mines have not realized its advantages and potential. benefit. At present, attention is still paid to semi-automatic and auxiliary operation control as an intermediate buffering technique. For example, bit positioning, drilling speed, pressure and hole depth control for open pit and underground mine rigs ; unmanned technology has been successfully applied in areas such as shovel, wheel loader and scraper excavation control. Due to the practical use of GPS, radio communication and laser technology, the measurement and drilling operations of open pit mines have also been unmanned.
4.2 Digitization and Intelligence of Mines The 21st century is a century of rapid development of various modern technologies. “Digitalization†and “intelligence†have become important indicators of the knowledge economy. The rapid development and application of information, positioning, communication and automation technologies have profoundly affected and changed the traditional mining industry. Internationally, the development of digital mines is very rapid. The informationization of mines in mining in developed countries has taken solid steps, and some have formulated long-term development plans. Canada began researching remote-controlled mining technology in the early 1990s with the goal of remotely operating the entire mining process. A prototype system has been developed and piloted at several NICO underground nickel mines to achieve ground-level underground mines. control. Canada has developed a plan to be implemented in 2050, in which a mine in a remote area of ​​northern Canada will be realized as an unmanned mine, and mechanical automatic crushing and automatic cutting mining will be carried out from all the equipment of the mine from Sadbury through satellite; Finland The mining industry also announced its own intelligent mining technology program in 1992, covering 28 topics including real-time mining process control, real-time resource management, mine information network construction, new machinery applications and automatic control. Sweden has also developed a Gofunteeknlk2000 strategic plan for mining automation. Some domestic GIS companies, such as Beijing Oriental Titan Company and Beijing Lizheng Company, have achieved good results in the true three-dimensional display of geological bodies.
4.3 Non-harm mining (clean mining)
Although no waste mining has made some progress, in the long run, no waste mining is still one of the important topics for the sustainable development of mining in the 21st century, both in China and the world.
4.4 Deep mining [4]
With the development and utilization of shallow easy-to-harvest resources, the development of underground metal resources has gradually developed in the depth direction. Compared with shallow buried deposits, the geological structure, occurrence conditions and ground stress of deep ore are different from those of shallow ore, and the mining technical conditions are more complicated, facing more extensive and more complicated technical problems. Such as ground pressure, high temperature lifting, mining, filling, drainage, ventilation, support, environmental protection, etc. There are different views on the definition of “deepâ€. The broader understanding is that, based on depth, >800-1000m is deep mining. According to incomplete statistics, there are more than 80 metal mines with a depth of over 1000m. According to the data of the last century the early 1980s, foreign mining depth of more than 000m of non-coal mines, Canada 30, 15 South Africa, the United States 11, India 4, Australia 4, Russia, Poland, Spain, Zambia Each of the two, Ukraine, Norway, Japan, Britain, Hungary, Mexico, Zimbabwe and other countries, mainly concentrated in South Africa, Canada, the United States, India and other countries. Most gold mines in South Africa have a depth of more than 1 000 m, including deep gold mines in the west, with a mining depth of 3,700 m and a depth of 4,500 m. In 2010, 60% of South Africa's gold production came below 2000 m depth. In the Coral gold mining area of ​​India, three gold mines have a depth of more than 2,400 m, and the Qian Pienry gold mine has developed 112 stages with a total depth of 3,260 m. Russia Krivoy Rog iron mine, have Dzerzhinsky mine mining depth of eight quasi-Kirov, the Communist International and so on up to 910 m, depth has been to open up to 1 570m, the future is expected to reach 2000 ~ 2500 m . With the rapid development of the national economy, the country's demand for metal products continues to increase. China's superficial non-ferrous metal deposits are about to be exhausted. According to statistics, in the next 10 to 15 years, one third of China's non-ferrous metal mines will reach or exceed 1000m. Currently HONGTOUSHAN copper mine to open up to a depth of 1340m, Gongchangling pioneering iron ore depth from the surface of about 1000m, deep ore bodies Huize lead-zinc mine to open up to 1571m, Yunnan Red Hill Iron, Guangdong Fankou The mining depth is close to 1000m, the depth of the Dongguashan copper mine is 1100m, the mining depth of Xiangxi gold mine is over 850m, and the mining depth of the Jiapigou gold mine is 1200m. In addition, the Shouwangfen copper mine, Fankou lead-zinc mine and Jinchuan nickel mine many mines Rushan gold, tin ore and other peak, will step into the deep mining.
4.5 Large-scale, automated and intelligent mining equipment The annual output curve of an underground mine in the United States [5]. Every time the production tool is innovated, the mine output doubles. After the mechanized mining method, the renewal cycle of the production tools is greatly shortened.
The general trend in the development of mining equipment is that mining equipment is becoming more sophisticated and more reliable, and productivity is increasing. The development characteristics of mining equipment is that the equipment is equipped with Jackie Chan, with high degree of mechanization; equipment is derailed, hydraulic, and highly automated; equipment technology is mature, and new technologies such as driverless and robotic operations have been successfully introduced. The trend of large-scale mining equipment is very obvious in open pit mining. Although underground mines are limited by space, they are still developing towards larger mining equipment. The main performances are as follows: 1 The large-scale automobile is not only reflected in the load capacity of the car, but also in the installed capacity of the car. 2 In order to support mining vehicles, excavators and loaders are also expanding.
(2) Remote control technology.
Many foreign companies actively apply remote control technology to metal mines. For example, Swedish LKAB company uses advanced remote control technology in its underground iron mine. One person can remotely control three scrapers at the same time. Canada's INCO company uses underground communication and positioning. With guidance and process monitoring technology, remote control mining equipment and process systems, various remote control technologies such as drilling, blasting, shovel and shotcrete have been successfully developed. With the advancement of telemetry, data communication and data processing, and robotics, remote control technology will become a common feature of future mining.
(3) Automation technology. In the past 20 years of global mining technology development, the development of mining mechanization has promoted the transformation of mining technology, and mining automation and information technology will play a leading role in the transformation of mining technology in the next 20 years. Automation technology, although widely used in mineral processing, has not been recognized by most mines for its advantages and potential benefits. At present, attention is still paid to semi-automatic and auxiliary operation control as an intermediate buffering technique. For example, drill bit positioning, drilling speed, pressure and hole depth control for open pit and underground mine rigs ; automation technology has been successfully applied in areas such as shovel, wheel loader and scraper excavation control. Due to the practical use of GPS, radio communication and laser technology, the measurement and drilling of open pit mines has also been automated. Automated mining technology can be used to solve mining problems under various harsh conditions, such as unstable slopes, poor safety conditions, and difficulty in ventilation.
4.6 The production safety is continuously improved, and the mining system is becoming more and more perfect. The core of the mining system is the mining method and process. With the improvement of the mechanization level of the mine, the structural parameters of the existing mining methods will inevitably undergo a series of changes, and the stope structure The concept will also change, and each process will develop in a more effective, safer and more reliable direction.
(1) Modernization of mining monitoring methods. The rapid development and application of information, positioning, communication and automation technologies have profoundly affected and changed the traditional mining industry. By monitoring the stope process, remote operation of underground mining equipment and even the entire mining system can be realized. Remotely controlled mining, unmanned work surfaces and even unmanned mines have become a reality in countries such as Canada, Sweden, the United States, and Australia.
(2) Improve the structural parameters of the stope. According to the conditions of mining equipment and mining technical conditions, gradually expand the structural parameters of the stope, increase the mining intensity, reduce the unit mining and cutting project and the ore loss depletion indicators, and improve the economic benefits of the mine.
4.7 Integrated Technology of Mining System Integration is an inevitable trend in the development of information technology and an important guarantee for making full use of information resources.
