Abstract

The invention uses an electronic detonator and non-electronic detonator combination mode to range different modes of the electronic detonators and non-electronic detonators in cutting holes, stop holes, profile holes and ground holes, and uses an optimal delay time to realize explosion of the electronic detonators and non-electronic detonators, thus effectively controlling the overbreak and vibration, and improving the speed of tunnel progress. An explosion method using the electronic detonator and non-electronic detonator combined mode includes the steps of: 1, dividing an explosion mining area into a cutting area, a stop area, a profile area and a ground area; 2, arranging the electronic detonators in the cutting area and profile area, arranging the non-electronic detonators in the stop area and the ground area, and connecting the electronic detonators and non0electronic detonator by conducting wires; 3, setting a delay time by considering the explosion delay time of each hole in each area of the explosion mining area and the error range of the detonators; and 4, carrying out explosion according to the sequence of the cutting area, the stop area, the ground area and the profile area.
