Almost all the coal seams in China are characterized by high gas content, extremely low
permeability, complicated geological structure, thus, natural disasters such as gas explosive …

Dominant frequency attenuation is a significant concern for frequency-based criteria of
blasting vibration control. It is necessary to develop a concise and practical prediction …

With the wide application of electronic detonators in blasting engineering, further study of
frequency spectrum characteristics under precise delay time is essential for blasting design …

The error of precise initiation time controlled at the microsecond level in the electronic
detonator blasting is accurate enough to realize blasting vibration reduction; however, the …
