The invention provides an initiator cascade control initiating device and method, and belongs to the technical field of electronic detonators. The device comprises a host initiating module and a plurality of extension initiating modules, wherein the host initiating module is connected with the extension initiating modules; and each extension initiating module is connected with a plurality of electronic detonators. According to the initiating method, the host initiating module is controlled by a software/hardware system to send out an initiating instruction, the extension initiating modules start to delay, the extension initiating modules send the initiating instruction to the electronic detonators after delay is finished, and the electronic detonators correspondingly delay initiation according to the set delay. Through the cascade control initiating device, the total number of the on-load electronic detonators can be increased, and the initiating delay can be greatly prolonged. By means of the initiating meth
