The invention relates to a blasting network reliability test tracer method, which is applied to the blasting network reliability tests of various rock-soil blasting engineerings and demolition blasting engineerings. The method comprises the following steps: selecting test sites, drilling holes with drilling equipments on the test sites, using rows instead of circuit branches and drilled holes instead of powder chambers or cartridge bags; selecting qualified blasting caps of each section and numbering the blasting caps, networks and drilled holes; according to the blasting design network diagram, linking the end lines of the blasting caps of each hole to form a network branch line, erecting high speed cameras, connecting the high speed cameras with computers by optical cables, initiating the network by an initiator, counting down before initiation and simultaneously starting the computers to capture images. The method has the advantages of ensuring precision, safety and reliability of engineering blasting networks, thus being a major technical breakthrough in blasting network test and test study.
