The invention provides a control and detection method for a blasting network. In the method, a blasting technology is combined with a signal system technology, a computer technology and the like, signal acquisition, emission and receiving are performed, and the blasting network connecting way, the blasting situation and the like are displayed indirectly by using the computer technology simultaneously. Due to the adoption of a control and the detection technology for the blasting network, the blasting network is controlled and detected in blasting engineering, and the aims of monitoring the blasting network and detecting whether a blasting device is allowed to blast and whether a misfire hole or a blind hole exists are fulfilled. Due to the adoption of the method, the monitoring of the blasting network can be enhanced, the detection for the misfire rate of the blasting network is increased, and the supervision of the service condition of the blasting device is enhanced; and the method has the advantages of easiness for constructing, easiness for comprehending, safety for using, low cost and the like.
