APPLICATION OF ELECTRONIC DETONATOR IN GEOTECHNICAL DEEP-HOLE BLASTING AT URBAN DISTRICT

Nonel detonator and electronic detonator were used in geotechnical deep-hole delay blasting to minimize the influence of blasting vibration during the project blasting construction in which the blasting center was very near to residence.The results of blasting vibration were contrasted by vibration monitoring test in spot field.The contrast analysis shows that electronic detonators have the advantage in reducing blasting vibration and improving blasting efficiencies.The intended application purpose was realized.The blasting technical experience can be referenced by similar projects.
