Abstract：This study addresses the critical engineering challenge of drainage and water-release boreholes in high-pressure water-bearing strata in underground mines.It provides a comprehensive in-vestigation into hole-wall protection materials and their associated construction techniques.By system-atically analyzing the composition,properties,and functional performance of protection materials,a-long with the detailed examination of various construction processes,the study aims to establish a ro-bust theoretical framework and offer practical guidance for the safe implementation of drainage and water-release boreholes under high-pressure conditions.The findings demonstrate that the selection of suitable hole-wall protection materials,combined with scientifically optimized construction techniques,significantly enhances the stability of boreholes by counteracting the pressures exerted by high-pressure water-bearing strata.This research holds substantial importance for ensuring the safety and efficiency of underground mining operations.
