Advanced water control method for ultra-deep well construction

The invention relates to an advanced water control method for ultra-deep well construction, and belongs to the technical field of mine ultra-deep well construction. According to the advanced water control method for ultra-deep well construction, drilling and grouting are carried out in advance, and an effective curtain grouting body can be formed around a drilling well, so that underground water is prevented from permeating to the periphery of the drilling well, effective water control is carried out on a planned well construction system, and safe production is guaranteed. According to the method, by determining the first diameter value and the number of the grouting holes, it can be guaranteed that grouting liquid effectively permeates into the stratum, and an effective curtain grouting body is formed. According to the method, by adopting an inclined hole forming mode, the uniformity and efficiency of grouting can be improved, and the consolidation and reinforcement effects of the stratum are achieved.
