Abstract
A nonelectric blasting system, method and device is disclosed for use in establishing a time sequential firing of blasting elements, the device comprised of an elongated tube which contains a low velocity deflagration mixture adhered to the inner walls of said tube. The device, by itself, controls a desired initiation pattern of a plurality of blasting elements by transmitting an initiation signal at a much reduced velocity than conventional shock tube or explosive cord by use of preselected material mixtures.
