AI Technical Summary
Traditional drainage hole construction suffers from drainage blind spots, drilling accuracy deviations, and delayed sealing of sudden water inrushes in high-risk tunnels, making it difficult to meet the needs of rapid pressure relief and precise control in water-rich and fractured strata.
By adopting an intelligent quantitative analysis system that integrates multi-source data, and through algorithm optimization and parameter correction, combined with numerical simulation verification, we can achieve accurate identification of rock strata characteristics and optimal matching of borehole diameters, thus ensuring the stability and efficiency of borehole-targeted drainage construction.
It avoids drainage blind spots, improves the timeliness of dealing with sudden water inrush, significantly enhances the stability and efficiency of borehole targeted drainage technology, and reduces the possibility of sudden water inrush.
