On November 29, Shaanxi Coal Caojiatan Mining Co., Ltd. successfully 122104 the world's first 10-meter ultra-large mining height intelligent fully mechanized mining face and supporting equipment in heavy-load trial operation, marking that the working face has successfully entered the initial mining and initial release stage and officially mined the first coal.
MG1200 3350-GWD intelligent shearer for coal cutting (the machine is independently developed by Xi'an Heavy Equipment Group West Coal Machinery Company).
Awesome, it will create four world firsts after completion
After the working face enters normal production, the annual output will be increased from the current 13 million tons to more than 20 million tons, the production capacity will be increased by more than 15, and the whole train car will be filled with a knife of coal in 40 minutes, which will exceed the traditional coal production efficiency by 15 times. According to the existing equipment level, it will create four world firsts in "installed power, total weight of equipment, full height of one-time mining, and single-sided production capacity", and will become a smart demonstration coal mine in the new era with the highest per capita work efficiency, the strongest intelligent integration, the greatest economic benefits, and the widest social influence. According to estimates, the rate of coal resources has increased by more than 10%, with an annual increase of 1.5 billion yuan.
Explore the many challenges of the industry
The 10-meter ultra-large mining height intelligent fully mechanized mining face is the highest mining height in the world, with a buried depth of about 363 meters, a strike length of 5,977 meters, a tendency length of 300 meters, and an average coal thickness of 105 meters, recoverable reserves of 2311270,000 tons, which is the fourth working face in the east wing of the mine's 12 panels.
The construction of the working face faces many problems, including how to safely and efficiently mine the full height of the super-large mining faceHow to solve the control of surrounding rock in ultra-large mining spaceWait a minute.

Fill the technology gap in the industry
As the "first person to eat crabs", Caojiatan Mining Co., Ltd., together with a team of academicians and experts of the Chinese Academy of Engineering, successfully developed the project of "Key Technology and Complete Equipment for 10-meter Ultra-thick Coal Seam Super Large Mining Height". The project not only creates a new height of global coal mine support, coal mining and transportation equipment, but also fills the gap of the full high technology of one-time mining of extra-thick coal seams, marking another major breakthrough in China's domestic coal equipment and coal mining technology.
At the same time, the working face fully adopts localized equipment, equipped with large-scale intelligent fully mechanized mining equipment, with intelligent functions such as first-class monitoring, one-key start, remote control and memory coal cutting, automatic machine shifting, pushing and slipping, and real-time monitoring of coal flow.
