This review summarizes the development and application status of explosive network multi-point initiation technology and in-line multi-point initiation technology. The application status of multi-point synchronous explosive network and multi-point logical explosive network were introduced respectively， and their advantages and disadvantages were analyzed. The research status of in-line multi-point initiation technology at home and abroad was compared， and the gaps in the current in-line multi-point initiation technology were pointed out. The influence of parameters such as the number of initiation points， initiation position on the output of the multi-point initiation system were summarized. The future research directions of multi-point initiation technology were pointed out： precise control of multi-point initiation， modularization and integration of multi-point initiation devices， low-cost multi-point initiation technology， and safety and reliability of multi-point initiation devices in complex environments.
