AI Technical Summary

Technical Problem

Existing methods for controlling rock blasting vibration rely on empirical adjustments. Ordinary detonators have low delay accuracy, making it difficult to accurately control the propagation of blasting seismic waves. They cannot effectively counteract or weaken the superposition effect of seismic waves and do not fully incorporate the geological characteristics of the rock mass. This results in poor vibration control in complex rock blasting, affecting the stability of rock slopes and the efficiency of mine production.

Method used

By employing digital electronic detonators with precise time delay, combined with rock mass geological feature detection, a blasting seismic wave propagation analysis model is established. The blasting hole network layout and delay time design are optimized, an initiation network is built, and parameters are iteratively adjusted through real-time monitoring to achieve closed-loop control of the entire process.

Benefits of technology

It significantly improves the accuracy and safety of blasting vibration control, reduces the cumulative damage of blasting vibration to rock slopes, improves the efficiency and safety of mining operations, and adapts to the personalized blasting needs of different types of rock masses.
