The invention discloses an electronic detonator and detonating cord combined detonating network and a construction method thereof. The detonating network comprises an electronic detonator, a detonating cord and a buckle, the construction method comprises the following steps: (1) drilling holes in a tunnel face according to hole net parameters of blast holes; (2) loading explosives and electronic detonators into the bottom plate holes, and loading explosives and detonating cords into other blast holes; (3) connecting branch detonating cords in other blast holes which are detonated at the same time by using a main detonating cord according to the detonating network; (4) connecting the explosive in the detonating blast hole with an electronic detonator with a set delay; (5) connecting all the electronic detonators to a main line in parallel; and (6) after the detonating network is detected to be qualified and the detonating warning is completed, detonating by a blaster in a safe place. The detonating network can
