"Remote mine, it's that simple" Remote mine release is as simple as that ——Henan Jinyuan Company to build a smart mine documentary â–¡ Reporter Xu Yong Zhang Liqiang (left), an engineer at Changchun Gold Design Institute, introduced the automatic control system of the pump house to the reporter. "In the past, two people were required to load the mine with the electric vibrating machine. One person was responsible for driving the electric motor car. One person was responsible for controlling the electric vibrating loader and directing the action of the electric motor vehicle driver." Henan Jinyuan Gold Mining Co., Ltd. Engineer Chen Wuchang said. The general operator and the driver of the electric motor car rely on the electric bell to communicate. This operation mode not only makes the loading process more troublesome, but also has low work efficiency, and increases the number of underground personnel and increases the safety hazard. “Reducing costs and increasing efficiency†and “mechanized substitution, automation and reduction of people†are the goals that the current gold mining enterprises are tirelessly pursuing. This is especially true for Henan Jinyuan, which is not a good resource endowment. In order to achieve the reduction of staff and efficiency, Henan Jinyuan Company commissioned Changchun Gold Design Institute to develop a remote control loading and unloading system for underground electric vehicles. The driver of the electric motor car can easily control the remote loading of the electric vibrating loader in the car. Conducting ore loading simplifies operating procedures and reduces production costs. In addition, Henan Jinyuan Company's underground pump house used to be guarded for 24 hours, which invisibly increased the safety hazard. Changchun Gold Design Institute designed the unattended control system of the pump house for the actual situation of Henan Jinyuan Company. The operator can be in the central control room. Controlling the pump house effectively eliminates safety hazards. Simple and practical When the reporter visited the underground, the operator was using the remote control and loading system of the electric motor vehicle for loading and unloading. I saw that the motor car stopped and stopped. After a while, a locomotive of more than 30 meters long was filled with ore, and the operator did not even show it in the whole process, and always remotely controlled in the cab. “It took only 5 minutes, and the employees of Henan Jinyuan Company learned how to operate.†Zhang Liqiang, an engineer at Changchun Gold Design Institute, said. The operation of the remote control and loading system of the electric motor car is very simple. It only needs to control the two switches “start†and “stopâ€, and the employees are very easy to use. The underground environment of the mine is very complicated, not only the air is humid, but also the light is dark, so the smoke and vibration are relatively more, which brings many difficulties to the underground automation control. When designing the system, Changchun Gold Design Institute fully considered all kinds of complex environments in the underground and carried out special treatment in each key part of the system. In the remote control loading and unloading system of the electric motor vehicle, the video operation monitoring system is the “eye†of the driving operator, and is a window for understanding the working condition and implementing the operation operation, in order to ensure that the driver of the electric motor vehicle can also drive the electric motor vehicle at the same time. The real-time operation of the trolley at the mine point was observed. The system used a waterproof and dustproof wireless network camera to monitor the mine. “The video operation monitoring system can be visually monitored 24 hours a day, while the remote control distance is between 50 meters and 100 meters.†Zhang Liqiang said. In the remote control loading and unloading system of the electric motor vehicle, the remote control of the electric vibration discharge machine is the key to realize automatic ore mining. To this end, Changchun Gold Design Institute has built a remote control electric vibration discharge machine automatic control system, in addition to the realization of the start and stop of the electric vibration discharge machine, at the same time can also feedback the motor running state of the electric vibration discharge machine, failure The alarm is immediately issued, so that the automatic control system of the remote control electric discharge machine has high execution efficiency and operational safety. “The electric box of the remote control and loading system of the electric motor vehicle can be explosion-proof, dustproof and shockproof, and can adapt to various complicated environments in the underground.†Liu Xu, an engineer of the Changchun Gold Design Institute, said that the entire system is modularized. In case of failure, you can go to the store to purchase, to facilitate the daily maintenance and update of the system. The unattended control system of the underground pump house not only can realize the operation of the well, but also can set various parameters of the pump. At the same time, it also has an alarm system and an emergency mechanism to ensure that the underground can be drained normally when unattended. "Everyone has generally responded well to the remote control loading system of the electric vehicle and the unattended control system of the pump house. Both of them indicate that the operation is simple and practical." Chen Wuchang said. Broad prospects Compared with some large-scale underground automation control systems, the remote control and loading system of the electric motor vehicle and the unattended control system of the underground pump house are not very complicated, but they bring great benefits to Henan Jinyuan Company. Henan Jinyuan Company currently has 14 mine discharge points in the underground. In the past, each mine release point required two people to cooperate. The remote control ore loading system of the electric motor vehicle and the unattended control system of the underground pump house not only help to reduce costs and increase efficiency, but more importantly, reduce underground personnel and reduce safety risks. “If there is more than one person downhole, it will be more dangerous.†Chen Wuchang said that these two automation systems have improved the intrinsic safety level of underground operations, which is the biggest benefit for Henan Jinyuan Company. However, for Henan Jinyuan Company, the remote control and loading system of the electric motor car has been given more important significance. Due to the influence of objective factors such as the size of the gold mine, the selection of the downhole motor vehicle equipment, and the well construction project, the remote control technology and remote-controlled loading technology of the electric vehicle in the gold mine are still in a blank stage. The remote control and loading system of the electric motor vehicle can improve the reliability and safety of the mining process of the gold mine, realize the automation and high-efficiency mining production, promote the integration of the two industries, realize the construction of digital mines, and enable the mining process to adapt to the fierce international competition. Very important strategic significance. Chen Wuchang believes that for Henan Jinyuan Company, the remote control ore loading system of electric motor vehicles is the foundation of digital mines. It is of great significance for enterprises to form new development advantages in order to seize the strategic high point of new economic and technological development. “After the implementation of Henan Jinyuan Company, these two projects can be widely used in mining enterprises affiliated to China National Gold Group Corporation. On this basis, the possibility of many applications can be evolved. With the improvement of mine automation, its market prospects are extremely high. Broad," said Zhang Liqiang.
