Special Issue Information

Dear Colleagues,

This Special Issue focuses on the latest scientific research and pioneering industrial applications of advanced blasting technologies. It aims to bridge the gap between theoretical innovation and practical implementation, addressing the growing demands for precision, safety, efficiency, and environmental sustainability in engineering blasting operations across mining, civil construction, and quarrying.

Potential topics include, but are not limited to, the following:

  • Digital and Intelligent Blasting: Integration of AI, machine learning, intelligent blast design, real-time monitoring, and data analysis.
  • Blasting Theory: Blast wave propagation characteristics and crack propagation behavior of rocks under blast loading.
  • Precision-Controlled Blasting: Techniques such as pre-splitting, smooth blasting, and trim blasting for improving slope stability and excavation control.
  • Advanced Initiation Systems: Research on electronic detonators and their precise delay timing for improved fragmentation and vibration control.
  • Case Studies and Hybrid Techniques: Innovative applications in complex environments, such as urban excavations, underwater blasting, and combined mechanical blasting methods.

The post-peak failure and softening mechanisms of surrounding rock in common tunnel, mine shaft, and roadway engineering primarily include radial tensile softening, shear sliding softening, and circumferential compressive–shear softening. Given the distinct post-peak failure and softening mechanisms, the softening coefficient in self-similarity analytical algorithms for stability analysis should differ accordingly. In this paper, to address the limitation of the existing self-similarity numerical algorithms for the deformation and failure of rock surrounding circular excavations—which typically employ only the plastic shear strain as the softening coefficient—we extend the self-similarity numerical algorithm by incorporating two additional softening coefficients: the maximum and minimum plastic principal strain. We validated the extended algorithm’s accuracy and reliability by comparing its stress, displacement, and plastic zone radius predictions with those obtained through numerical simulation and engineering monitoring and examined its sensitivity to step length variations under various softening coefficients and yield criteria. According to the validation and comparison with existing algorithms, the extended algorithm extends the applicability scope of the original self-similarity numerical algorithm and significantly improves the accuracy of the calculated results. Finally, using the extended algorithm, we systematically compared and quantitatively analyzed the stress, deformation, and failure characteristics around a circular excavation across different softening coefficient categories, including their critical values, revealing the influence patterns of the softening coefficients and their critical values on the stability of engineering surrounding rock.

During drill-and-blast construction, complex and variable rock masses are frequently encountered. Owing to the transient nature of the explosion process and the randomness of crack propagation, the response of different rock masses to explosive loading is highly intricate. This study primarily investigates the dynamic response of rock masses with varying strengths under two different charge configurations. First, four cement mortar specimens of differing strengths were prepared then subjected to general blasting and slit charge blasting, respectively. High-speed cameras and digital image correlation techniques were employed to capture and analyse stress wave propagation and crack propagation during detonation. Fractal dimension analysis was subsequently employed to quantify and compare the extent of damage in the specimens. Findings indicate that rock strength influences stress wave attenuation patterns: lower-strength rocks exhibit higher peak strains but faster decay rates. Crack propagation velocity was calculated by deploying monitoring points along fracture paths and defining fracture initiation thresholds. Higher rock strength correlates with both peak and average crack propagation velocities. Slit charge blasting effectively optimizes damage distribution, concentrating it within the intended directions while reducing chaotic fracturing. These findings provide scientific justification for blasting operations in complex rock formations. Full article
