Application of wavefront reinforcement model for reduction blast-induced ground vibration [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2018
Ground vibration from blasting is generally controlled by reducing the explosive charge weight per delay. However, lowering explosive charge weight per delay may increase the fragmentation size of blasted material.

Effective Assessment of Blast-Induced Ground Vibration Using an Optimized Random Forest Model Based on a Harris Hawks Optimization Algorithm

Applied Sciences, 2020
Most mines choose the drilling and blasting method which has the characteristics of being a cheap and efficient method to fragment rock mass, but blast-induced ground vibration damages the surrounding rock mass and structure and is a drawback. To predict,
