Abstract
Electronic blasting systems typically permit blasting with detonator delay times having millisecond accuracy. Disclosed herein are blasting apparatuses and methods of blasting that are capable of even higher degrees of delay time accuracy, for example involving programmable delay times selectable to an accuracy of about 0.25 ms, 0.1 ms, or better. Such methods and apparatuses present unprecedented and unexpected advantages for both mining applications, civil engineering uses, and in seismic prospecting.
