Abstract:Characterized by easy connecting networks, high tensile , good performance in temperature,oil and water resistance,small damage to the in-hole explosive in the process of detonation and directionless in sensitizing explosion,a new low-energy fuse detonating system which was used in San Gorge work is described in this paper. This detonating system is suitable for the blasting in which the explosive without cap sensitivity is charged,especially when charging by use of the emulsion explosive mixing and loading truck.
