The large-scale tunnel full section mining machine is the first domestically developed and the world's largest full section potassium salt mining machine in China. It is a solid potassium salt mining equipment that integrates multiple functions such as continuous cutting, loading and unloading, walking, dust removal, inertial navigation, wireless remote control, etc. It is a leapfrog technological revolution in China's solid potassium salt mining process, and is of great significance for promoting the comprehensive mechanization and intelligence of potassium salt mining. In order to solve the localization problem of the core components of the tunneling machine, improve the shortcomings of low excavation efficiency and poor continuous operation ability, this excavator has been innovatively developed. It breaks through the problem of the shield machine forming a full section and unable to operate continuously. It is designed by combining the shield tunneling technology of tunnel excavation and the cantilever tunneling technology of the tunnel. The full section is continuously cut, the tunnel is formed in one go, the excavation section reaches 25 square meters, the excavation speed is 0.3 meters per minute, and the transportation capacity exceeds 1500 tons per hour. It is an important milestone in the development of coal mining equipment in China.The excavation efficiency is 10 times higher than the domestic average level. A large tunnel full face excavation and mining machine and a team of 80 people are equivalent to 12 ordinary excavation machines and a team of 500 people, greatly improving excavation efficiency and significantly increasing coal production.The design concept comes from the flowing architecture of Zahahadid, which is elegant and rhythmic, with a simple and powerful overall style that is calm and atmospheric, showcasing the quality and professionalism of large tunnel full face mining machines.Changing traditional excavation techniques, achieving remote control operations for nearly 100 meters, improving the working environment and conditions of underground workers, leading the upgrading of industry products, and promoting industrial upgrading.
