Recently, the intelligent inspection robot of the canal coal mine coal washing plant "went to work" and officially opened a new journey of "unmanned inspection + remote monitoring" intelligent inspection. "Since the coal washing plant has used this guide-rail mobile inspection robot, we can accurately grasp the relevant data through the computer control interface, and no longer need personnel to frequently shuttle between narrow and slippery corridors to 'visualize' inspections." Shao Feng, the person in charge of the mine's coal washing plant, introduced.
This is just a microcosm of the canal coal mine's promotion of intelligent mine construction. In recent years, Canal Coal Mine has adhered to the idea of "rather a million equipment than a hundred thousand to increase one", and promoted the construction of intelligent mines by increasing the intensity of "mechanized substitution, automation and personnel reduction", improving the level of mine equipment, optimizing mining technology, strengthening safety management and other measures to achieve mine quality and efficiency.
Equipment is reinstalled, and intelligent mining is constantly upgradedWith the pressing of the start button, the employees of the first district of the canal coal mine comprehensive mining started the equipment with one key in the underground comprehensive collection and control center nearly 100 meters away from the working face, and the whole set of comprehensive mining units of the intelligent comprehensive mining face was successfully started. In the electronic screen of the surface production dispatching command center, it can be clearly seen that the coal mining equipment in the underground working face is automatically running, cutting coal, moving frames, pushing and transporting, everything is orderly, and the operation scene is in full view.
Intelligent excavation is an indispensable part of the construction of intelligent coal mines, and canal coal mines promote excavation and efficiency with equipment upgrades. "The use of advanced equipment such as bolt drills, high-power TBMs, and self-moving tails has greatly improved the efficiency of boring." Zhou Fale, deputy mine director of the mine, said that the intelligent all-rock TBM was put into service, and this model of TBM is suitable for rock tunnel boring, which is nearly 30% more efficient than the previous TBM. The remote control belt conveyor introduced by the mine moves the tail of the machine, which plays a huge role in improving the efficiency of the tunneling. "The tail of the self-moving machine can be operated remotely during the pulling process, which reduces the risk of mechanical injury and reduces the physical labor of employees. The original work that required at least 3 people to pull and move for about 5 hours, now up to 2 people can complete the work in 1.5 hours, and after skilled operation, it can be completed in 1 hour by 1 person, improving the work efficiency by nearly 5 times. Yang Yi, the head of the mine excavation area, introduced.
In the underground roadway boring face support operation and monorail crane rail beam installation operation, the canal coal mine introduced hydraulic bolt drilling truck, which can realize the functions of top support, drilling, detection hole and track beam installation at the same time. "When installing the monorail crane rail beam, the hydraulic bolt drilling truck lifting platform can be lifted freely, and the lifting device can store 12 monorail lifting rail beams at a time, and can be traversed and lifted, so as to find the most suitable position, greatly reducing the labor intensity of workers, and improving quality and efficiency is very obvious." Wang Yunji, head of the mine's comprehensive excavation area, said.
"With 'mechanized substitution and automation reduction' as the starting point, we continue to make efforts in equipment upgrading, process optimization, reducing labor intensity, and building a solid safety environment, and a number of new equipment are continuously put into use, realizing the continuous upgrading of intelligent mining, the continuous improvement of coal mining and excavation efficiency, helping mines to build a solid safety defense line while achieving leapfrog development in reducing personnel and increasing efficiency." Xu Lei, head of the mine's electromechanical technology section, said.
Modernization, intelligent transportation is safe and efficientThe mine promotes the "three mention" working mode of "changing equipment to improve efficiency, changing technology to improve efficiency, and changing thinking to improve efficiency", and upgrades the equipment for transporting people, materials and coal to achieve safe and efficient transportation. "The three overhead occupant devices in use underground are all connected to the intelligent mine comprehensive management and control platform of the canal coal mine, which realizes the remote monitoring and control of the underground overhead occupant device on the ground, and all realize unattended." Zhu Zejian, Mechanical and Electrical Technology Section, introduced that the system combined with the personnel positioning system can realize the accurate positioning of passengers.
Monorail crane transportation plays a big role in the installation process of the working face, a whole set of hydraulic supports slowly lifting, moving forward smoothly, arriving at the predetermined place in 40 minutes, lowering, adjusting, rising, the process flow is completed in one go, and the construction efficiency has risen sharply. "Using a monorail crane to transport the entire set of hydraulic supports, which was difficult for eight people before, can now be easily completed by two people, and the transportation efficiency has been increased by more than four times." Wang Yangde, head of the preparation area, said that the installation of electronic eyes on the electrodeless rope winch instead of manual inspection is safer and more efficient; The use of permanent magnet drum motors makes belt transportation efficient and energy-saving.
Mine wire rope magnetic non-destructive flaw detector in the canal coal mine main and auxiliary shaft winch room put into use, the equipment has small size and easy to carry, wireless communication between the sensor and the host, can display the test curve, test location, running speed, broken wire status and other information in real time, to ensure the accuracy, timeliness, stability of wire rope monitoring. "The wire rope magnetic non-destructive flaw detector not only has real-time monitoring functions, but also can judge the real-time status of the wire rope through computer analysis, push the broken wire, wear amount and other data of the wire rope, make up for the shortcomings that the inside of the wire rope cannot be inspected during manual rope inspection, improve the efficiency of rope inspection, and provide a reliable guarantee for the safe operation of the main auxiliary well winch." Gao Yang, a winch maintenance worker in the mine's operation area, said.
The canal coal mine has invested in the belt centralized control system to reduce personnel and improve efficiency. "The belt in the seventh mining area is about to start, please pay attention to safety..." The female worker in the operation area of the mine started the underground transportation belt with one button in the surface centralized control room. The mining belt centralized control system can also switch the remote control and local control mode at any time, and watch the belt machine equipment parameters, belt temperature, mistracking, tearing and other conditions in an all-round way, so as to better realize the ground control belt start and stop. Wang Dongyuan, head of the mine's operation area, said.
File upgrade, intelligent washing and selectionWalking into the canal coal mine coal washing plant, a high-brightness "LED" lamp illuminates the entire workshop, the upgraded equipment is staggered, and the working environment is clean and bright. Through "intelligent transformation + 'four new' applications", the plant realizes the comprehensive upgrade and acceleration from "automatic" to "intelligent", and accelerates into the era of intelligent washing.
The original scattered equipment of the coal washing plant is uniformly included in the centralized control management, so that the centralized control system has more complete functions and wider coverage, and can carry out unified planning and collaborative processing of production, and effectively improve work efficiency. In the daily production process, centralized control personnel can harvest real-time images of the job site with just a click of the mouse, providing strong data support for washing decisions.
"We focus on intelligent inspection, intelligent selection, organizational optimization, etc., and empower the high-quality development of enterprises by building an intelligent, visualized and efficient influential brand of coal washing plants." Shao Feng, the person in charge of the coal washing plant, said that the centralized control and adjustment of raw coal washing volume project has achieved 'second' level of accurate adjustment of raw coal washing volume; the skid-mounted integrated machine replaces the three sets of equipment of cyclone group, slime arc screen and slime centrifuge, and the use of this new equipment further improves the efficient sorting efficiency of coarse slime, saves the consumption of various equipment and materials, and is expected to save more than 600,000 yuan in costs per year; After the intelligent inspection robot is "on duty", it can replace the on-site inspection of personnel, collect, store and transmit real-time data such as image, sound and temperature of the belt conveyor into the warehouse, and build a high-tech "intelligent defense line" for the safe and stable operation of the coal washing plant.
In recent years, Canal Coal Mine has continuously increased scientific and technological empowerment and steadily promoted the construction of intelligent mines. "In the first half of 2023, a total of 11 R&D projects were aggregated, and the collected R&D expenses increased by 73.3% year-on-year; Completed 4 achievement appraisals, 3 innovation achievements won awards, and 2 invention patents. In the next step, we will continue to accelerate equipment upgrading, focus on scientific and technological empowerment, accelerate the transformation of innovation achievements, promote the construction of intelligent coal washing plants, information management platforms, scientific and technological talent training, and scientific and technological research in key areas, and promote the high-quality development of enterprises with scientific and technological innovation.
