摘要
Abstract
Currently,major mining projects that involve downhole drilling encounter several challenges,one of the main issues is the significant inflow of water during the construction of deep boreholes,which severely hampers drilling operations.Therefore,it is essential to improve the existing construction processes to effectively address the difficulties caused by the large volume of water in deep holes.A study was conducted on the adaptability of cement slurry water-stopping technology and the use of segmented grouting materials.During the construction of solid core drilling in areas experiencing water influx,the segmented grouting method was employed.This approach aimed to seal off water inflow within the hole,ensuring a smooth drilling process.关键词
