Mining automation makes mining mining safer
"Since the end of July 2011 put into operation six months now, Shougang iron ore mining Xingshan to adopt 16 major economic indicators, there are already 6 to enter the top three in the same industry, of which two ranked first." Recently, Qian'an mining Hao Shuhua, the head of the company, proudly said that this benefited from the self-developed ground mining automation system. Recently, the author walked into the underground working area with the workers. The vehicle went down the slope at a slope of 30 degrees downwards. I didn't feel the panic that I had imagined before, but I felt that the slope was too narrow and went to the slope of -105 meters. When the road turns, I see the driver quickly heading to the left to enter the "parking belt". After a while, a mine car is full of ore whistling through, seeing the author's doubtful eyes, the driver's master explained that just a red on the left side of the roadside The flashing of the lights indicates that there is a reverse driving of the vehicle in this section. This parking zone is the escaping zone. This is a safe access to the mine through the ramp signal control system. The vehicle traveled to the No. 3 position in the mining operation area at -180 meters. The author saw that Li Hongyong, the leader of the blasting technology team, was leading the workers to prepare for the blasting operation. When the blasting wire was connected, the sudden illumination was extinguished, and it took less than 5 seconds. I heard the sound from the intercom: "Don't be afraid, maybe there is a short circuit in somewhere. We have started the power supply control subsystem and will be able to send power soon." Sure enough, less than 2 minutes, the lights lit up again. Li Hongyong said with a smile, once the danger occurs, the information is delivered in 5 minutes, from the location of the quick confirmation personnel to the rapid escape to escape, can be completed within 10 minutes. It was a bit scary to encounter this situation before, and now there is no worries. The implementation of blasting operations is also more confident. In the elevator elevator, the relevant technical personnel introduced that when there is a power outage in the underground, the ground attendant can immediately remotely test the power transmission. The self-developed power supply control subsystem adopts the microcomputer-based comprehensive protection automation management. The power supply system operation status fault diagnosis technical parameters and the power-off operation can be automatically completed by computer analysis to realize the monitoring of the underground substation remote control remote communication. Significantly shorten the troubleshooting time and reduce the loss caused by power failure. Entering the hall of the Xingshan Iron Mine Production Command Center, the staff is realizing the real-time operation status of the key parts under the mine through the automatic control system and video monitoring system. The on-site environment of the ore mining of various vehicles can be clearly seen. Clearly. "Real-time data transmission, like live TV." Engaged in mining 20 years of the State Production Safety Group of Experts on non-coal mining group members and is responsible for the mining project mining Xingshan, deputy general manager Qi Baojun told the author that they fully consider the characteristics of underground iron ore dust explosion humidity and other factors, combined with advanced information technology hard Research, integration and innovation of the underground mining of Ningshan Iron Mine, narrow-track signal collection control, downhole crushing control, ground dry selection control, ventilation control, drainage control, underground wired communication, WiFi-based underground vehicle positioning and underground wireless The 10 major automation control systems, such as communication, ensure the safe and escort of Xingshan Mountain, and realize the daily supervision and management of the real-time dynamic display of the movement of the personnel, which can effectively monitor the underground mining activities. It is reported that the mine automation control and management is the first application in China. There is no molding production experience and design specification requirements. The successful transformation from open-pit to underground mining has made Shougang Mining Xingshan Iron Mine the first large-scale modern iron ore mine in China. This practice has been a pioneering exploration for Shougang Qian'an Mining Company and continues to be an important raw material production base for Shougang, supporting the sustainable development of Shougang's steel industry and making a useful attempt.
