Abstract:
     The present invention relates to an inner cap type initiatorless industrial detonator. Its basic type includes shell body, secondary blasting charge, transition powder, inner cap and ignition powder etc. It is mainly characterized by that the charge of detonator only contains the ignition powder and general high explosive with high flame sensitivity, low mechanical sensitivity and greater detonating impact energy, and the length of detonator inner cap and dimension of fire propagating hole are appropriate. According to the requirements it can be fit with appropriate ignition element or delay element and various initiatorless instantaneous detonators or delay detonators (including various coal mine allowable detonators) are composed with ignition element, therefore it can be extensively used in various engineering demolitions.
