Is unmanned coal mining still far away?

As an important traditional energy industry in my country, the coal industry is an important part of China's national economy, and its intelligent construction is directly related to the process of my country's national economy and social intelligence.

It can be said that accelerating the intelligent construction of the coal industry is the only way and an inevitable choice for the coal industry to achieve high-quality development.

Core technology innovation is the key

For every 20 tons of coal produced in the country, 1 ton comes from Shendong coal.

During the "13th Five-Year Plan" period, Shendong Coal took the lead in the intelligent construction of coal mines, and completed the domestic leading Jinjie intelligent coal mine construction key technology and demonstration project, the Daliuta billion-ton regional coal mine centralized control project demonstration project and the upper Bay Intelligent Coal Preparation Plant Demonstration Project; Yujialiang Coal Mine, Jinjie Coal Mine, and Shigetai Coal Mine pioneered 3 intelligent fully mechanized mining modes; achieved full coverage of underground 4G and ground plant area 5G, and built a full-time and fully integrated data warehouse in the mining area; fixed Positions are gradually 0 on duty; the research and development and application of five major coal mine robots are fully covered.

In the practice of intelligentization, Shendong Coal has gradually realized that the advancement of core technology innovation is a breakthrough in the construction of intelligent mines.

One year later, the first domestic level coal mining equipment was successfully commissioned in the Shigetai Coal Mine.

The centralized control room located along the groove of the contour coal mining face is the intelligent center for directing the safe production of the working face.

More importantly, the equal height coal mining face changes the traditional long-wall oblique cutting coal mining method, adopting the vertical feed mode of the machine head and tail.

　　The successful practice of this working face not only fills the gap in the field of high unmanned fully automated production of thin coal seams in China, but also accumulates important experience in the automated, safe and efficient mining of thin coal seams with a recoverable reserve of 957 million tons, providing a useful reference.
.

　　Upgrade and extend the entire industry chain

　　While making breakthroughs in key technologies and key areas of intelligent mine construction, Shendong Coal also promoted the extension of intelligence to the entire mine system.
Since 2020, Shendong Coal Jinjie Coal Mine, Baode Coal Mine, Bulianta Coal Mine and many other mines have realized unattended main transportation system through intelligent upgrade and transformation of the main transportation system.

　　In Bulianta Coal Mine, two centralized control points placed at underground belt conveyors have been operating stably for more than 4 months.
At these two centralized control points, the start-stop control and operation of multiple belt conveyors within the corresponding control range can be completed.
Condition monitoring, to realize unattended escort for the mine owner's transportation system.

　　"The two centralized control points realize the remote centralized monitoring and control of the main transportation system.
Only one post is required.
This not only avoids the hazards and risks of personnel operations, but also reduces the labor maintenance cost of the main transportation system, and cumulatively realizes production shift positions.
The workforce was reduced by 30 people.
" said Lu Haibin, deputy captain of the operation team of the Bulianta Coal Mine.

　　According to the intelligent mine construction promotion plan, in 2020, the main coal transportation system of Shendong Coal will reduce fixed-post workers by 30%.

　　While intelligentization promotes the transformation of production models, the data it generates also provides important support for enterprises to carry out industrial control automation innovation research and development.
Now the Shendong production data management platform is a must-check application for Zhang Maowei, the head of the Yujialiang Coal Mine Quality Group of Shendong Coal, to open his mobile phone every day.
The platform integrates multiple functions and systems such as industrial video, real-time production data, production data analysis, personnel positioning, comprehensive mining pressure analysis, and equipment availability.
“Now you don’t need to go down the well or contact other people.
You can learn about the operation of the equipment by logging into the Shendong production data management platform on the mobile phone.
” Relying on data analysis to achieve precise equipment repair and maintenance, Zhang Maowei deeply felt the traditional Overhaul gap.
