Abstract: This paper described the principle of ultra-thin shotcrete support technology, analyzed the research progress of ultrathin
shotcrete support technology in coal mines in China and discussed the specific application of ultra-thin shotcrete support
technology in Kailuan Coal Mine. The application results show that this technology has the advantages of scientific and reasonable
design, superior material performance, and the overall technology meets the specific conditions of use in coal mines. It can meet
the requirements of closed support for ultra-thin coal mines and should be effectively promoted and used.

 Key words: coal mine excavation; ultra-thin shotcrete; support technology
