The intelligent inspection robot slowly moves along the preset track, with its "eyes" scanning the surrounding environment and equipment in 360 degrees; The underground intelligent comprehensive mining face is operated remotely by miners holding a remote control, and the support automatically moves with the machine; Unmanned aerial vehicles hovering in the air for daily geological hazard inspections
Recently, during an interview at the Xishan Coal and Electricity Malan Mine (hereinafter referred to as Malan Mine), the high-tech atmosphere was overwhelming. Intelligent devices have replaced traditional manual operations in coal mining, excavation, transportation, power supply, drainage and other operational processes, and coal production methods are undergoing technological changes.
The intelligent construction has enabled Malan Mine to move towards a new and greener direction, not only reducing the labor intensity of workers, but also greatly improving production efficiency and enhancing safety production capacity. Technology has become a catalyst for accelerating the development of new quality productivity in coal mines, "said Wang Xiaodong, Deputy Director of Malan Mine's Mechanical and Electrical Department, happily.
Fewer miners and Higher efficiency
The Malan Mine, with a mining age of over 30 years, is a large-scale modern state-owned mine that undertakes the important mission of ensuring energy supply. It is one of the first intermediate intelligent mines in Shanxi to pass the acceptance inspection.
Entering the production scheduling and command center of Malan Mine, a huge display screen catches the eye, showing in real-time various production processes inside the mine, with real-time video feedback and massive data updates. Wang Xiaodong introduced that this is the core of the digital management and control platform for safety production in Malan Mine, like the "smart brain" of the mine, which monitors and schedules every production process in real time to ensure safe and efficient production.
The reporter saw that the staff in the command center lightly pressed the button, and at a depth of 300 meters, the coal cutter blades of the mining machine flew and the hydraulic support extended and retracted back and forth. One ton of black gold poured down and was transported to the ground through the chain plate machine and belt conveyor.
Technology is the wing, and innovation is the soul. In recent years, Malan Mine has embraced high technology, with the integration of the Internet of Things, Internet transmission, digital integration, visual assurance, and procedural operations as its core objectives, and has made every effort to promote the construction of smart mines. "We have unified planning, bold innovation, and step-by-step promotion, and have built and put into use multiple intelligent comprehensive mining workfaces and intelligent coal roadway excavation workfaces. Multiple locations above and below the mine have achieved unmanned operation, "said Wang Xiaodong.
Intelligent technology is profoundly changing the traditional coal mining production methods. Wang Yujiang, Deputy Chief Engineer of Mechanical and Electrical Engineering at Malan Mine, gave an example that the double cantilever excavator anchor integrated machine used in the heading face, after being equipped with an intelligent system, has achieved continuity between tunnel excavation and anchor support, and has multiple intelligent functions such as remote control, excavation status and posture monitoring, and tunnel environment monitoring, making mine production safer and more efficient. According to statistics, intelligent construction has reduced a lot of manpower in Malan Mine, but increased production efficiency by more than 30%.
Smart devices are taking on more and more physical labor, while miners are more engaged in monitoring, maintenance, and management of mental work, "said Wang Yujiang with emotion." With fewer people, it's safe, and without anyone, it's safer
Coal mining without carbon emissions, the mine is like a park
Lawn, chrysanthemum, holly... Strolling through Lanxiu Park in Malan Mine, there is no trace of coal dust. Although it has entered winter, the greenery is still strong, and it is hard to imagine that this is a coal mine, or once a gangue hill. The beautiful scenery in front of us is a microcosm of Malan Mining moving towards greenery, "said Wang Xingya, the chairman of Malan Mining Association. While promoting the construction of smart mines, Malan Mining actively practices the concept of green development and strives to create a" zero carbon mine ".
Malan Mine has issued the "Promotion Plan for the Creation of Zero Carbon Mines", proposing to comprehensively promote green mining from the aspects of energy-saving transformation of mechanical and electrical equipment, comprehensive utilization of gas, exploration of "green electricity+ecology" mode in mines, intelligent mine construction, and innovation in carbon emission management.
In the main inclined shaft belt machine room of Malan Mine 201, more energy-efficient belt motors have been replaced, and high energy consuming motor equipment has been replaced with high-efficiency permanent magnet motor products. The energy consumption of the newly replaced permanent magnet motor has been reduced by half, "said Wang Yujiang. High efficiency and low-energy equipment not only improves work efficiency but also reduces carbon emissions, achieving two goals with one stone.
"Mashgas"is unconventional natural gas produced from coal seams, which was previously discharged as waste. In promoting the creation of "zero carbon mines", Malan Mine uses advanced technology to purify and compress gas, making it a clean energy source for surrounding areas to use. This not only reduces greenhouse gas emissions but also creates new economic growth points.
Wang Xingya said that Malan Mine is constantly exploring and innovating in the construction of intelligent mines. By introducing more advanced intelligent equipment and systems, it has achieved precise control and optimized management of various links in the mine. Not only does it improve production efficiency, but it also reduces energy consumption and carbon emissions.
Miners learn technology to adapt to intelligence
Master, I have fixed and optimized this switch... "On December 23, 2024, in the Malan Mine Workers' Innovation Studio, the master and apprentice gathered around a machine, discussing technical details. The construction of smart mines cannot do without high-quality miners, "said Wang Xingya." At Malan Mine, miners learn technology and adapt to intelligence, which has become a conscious and pursuit
Since 2002, Malan Mine has held an annual employee skills competition, which has continuously expanded its coverage and increased the number of participating occupations year by year. In recent years, new occupations have been added to adapt to the construction of intelligent coal mines, such as intelligent centralized control workers for comprehensive mining, intelligent inspection workers for comprehensive mining, and cloud computing workers.
We focus on the combination of 'certified employment' and skill competitions, using competitions to promote learning and learning to promote work, "said Xue Xiuli, deputy director of the Malan Mine Employee Education and Training Center. The skill competition has become a major platform for industrial workers to improve their quality, skills, and growth.

In order to improve the comprehensive quality of miners, Malan Mine has also held various safety knowledge training, multiple rounds of fully covered special training, safety production management personnel training and other activities to ensure that every employee can meet the required skills and knowledge for their position. According to statistics, a total of 39843 person-time staff received training, truly achieving full coverage of training and comprehensive skill improvement.
Malan Mine has also established a Model Worker Innovation Studio and an Intelligent Coal Mine Innovation Studio, providing a platform for employees to showcase their innovative talents. Xue Xiuli said that miners can exchange ideas, collide sparks, improve skills, and generate more innovative achievements here. At present, the innovation studio of the mine has applied for 31 national patent projects and more than 400 "Five Small" innovation achievements, and has emerged a large number of outstanding talents who have won awards in city level, provincial level, and national level skill competitions. Among them, there are 346 "technical champions", "technical role models", and "technical experts" in skill competitions.
The intelligent construction has propelled Malan Mine towards a new and greener direction. Nowadays, Malan Mine has become a model of high-quality development in the coal industry. "We will increase investment in technological innovation, continue to promote the construction of '5G+smart mines', replace manual operations with more intelligent equipment, and make the production environment safer and more efficient, "said Wang Xingya."
