Shock-tube Delay Initiating System, which consists of plastic connector block, Shock Tube, Trunk-line Surface Detonator and high-precision Delay Shock-tube Detonator, is a high –precision blasting network with capacities of hole-by-hole initiation and time –delay for both surface detonator and in –hole detonator. The system can be applied to blasting operation of tunneling and open deep-hole bench blasting. It also has obvious integrated efficiency of perfect blasting effects, small blasting shock, good blasting safety and high connection efficiency.

Technical Parameters

Shell material：aluminum, aluminum alloy

The length of shock Tube：2m (It can be determined as required by customer.)

Water resistance：Place the products into water at the depth of 30m for 24 hours; it shall be reliably fired during firing test.

Initiating power：The detonator can initiate 5 shock tubes passed through the plastic connector block at most. (Trunk-line Surface Detonator)

When tested on 5mm thick lead-plate, the diameter of hole burst in the plate shall be more than the outside diameter of the detonator. (High-precision Delay Shock-tube Detonator).
