Application of Cutting Hole Grouting Technology in Water Prevention and Control of Western Fully Frozen Vertical Shaft

In order to promote the application of cutting hole grouting technology to prevent water of fully frozen vertical shaft in western rich water and soft rock stratum, this paper took the water prevention and control of the main shaft of Dahaize Coal Mine as an example and introduced the field application and the effect of the cutting hole grouting technology in detail. The results show that rational utilization of this technology can successfully block the outer ring space channel of the frozen pipe, and has the function of sealing the water flowing fractures of the grouted formation to achieve the purpose of preventing and controlling water and ensure the safety of mine shaft.
