BLASTING METHOD OF ELECTRONIC DETONATOR AND NON-ELECTRIC DETONATOR MIXES

摘要

The present invention relates to a method of blasting a mixture of electronic detonators and non-electric detonators for obtaining the best result, by appropriate use when electronic detonators and non-electric detonators tunnel blasting. ; The invention has Gheshm ball (3), close to the ball (2) and a bottom hole (4) To this end, the method comprising mounting a non-electric detonator; Outside the hole (1), comprising: mounting an electronic detonator; And after the connection to the non-electric detonators and electronic detonator group of the known blasting with a delay time difference it consists characterized by blasting the front end surface. ; Using the electronic detonator of this invention only the outermost balls constructed as described above, and the rest is an exemplary to use a non-electric detonator perform near blasting excavation will line the most economical also minimize the damage to the surrounding rock mass, and Furthermore is the to increase the blasting efficiency by obtaining the beautiful to the wave front of the tunnel wall. ; The outer ball, around the ball, Gheshm balls, bottom balls, electronic detonators, non-electric detonator, blasting.
