AI Technical Summary

Technical Problem

In existing static blasting technology, the timing of construction depends on a single process quantity or human experience, which leads to delayed local borehole response, insufficient expansion, or asynchronous response of surface cracks, resulting in inaccurate judgment of the degree of cracking.

Method used

By integrating the temperature time series data, pressure time series data, and rock surface crack image sequence of blast holes, the temperature compliance characteristics, pressure stabilization characteristics, and crack propagation characteristics are extracted. The abnormal deviation coefficient is calculated, and the blast holes are divided into effective holes and abnormal holes. The crack completion index and the proportion of abnormal holes are used as dual constraints for row switching, and the correction control command is output to optimize the construction switching timing.

Benefits of technology

This improves the accuracy of determining the current cracking state of the boreholes, reduces the interference of local abnormal boreholes on the overall switching judgment, and reduces the possibility of continuing construction at the predetermined pace when abnormal boreholes appear, thus ensuring the continuity and stability of the construction process.
