ELECTRIC SUPER™ COAL - New Series

ELECTRIC SUPER COAL is a high strength, static resistant, electric detonator designed to provide precision and accuracy in all delay periods with no overlap. The copper-clad steel legwires allow for magnetic separation. The legwires on each delay period are easy-to-read tag displays the delay period and nominal firing time. The wire is HDPE insulation for added protection from extraneous currents. The copper shell reduces the possibility of water hammer effect. The detonator has a 900 mg RDX and/or PETN base charge.

 

ELECTRIC SUPER COAL detonators are specifically designed for the underground coal industry, meeting all requirements of the Mine Safety and Health Administration found in CFR 30, Parts 7.69(f) and 75.1310.

 

 

APPLICATION RECOMMENDATIONS

 

• Recommended firing current:

Series wiring: a minimum of 3 amps AC or 1.5 amps DC Parallel wiring: a minimum of 1 amp AC or DC per detonator Series-in-parallel wiring: a minimum of 2 amps AC or DC per series • The maximum recommended continuous firing current is 10 amps per detonator.

• NEVER use the ELECTRIC SUPER COAL with other types of Dyno Nobel electric detonators or electric detonators from another manufacturer. Wiring different brand electric detonators together in a blast circuit may result in misfires and is in violation of federal regulations. Even though some types of Dyno Nobel electric detonators are electrically compatible, they should never be planned to be used together as a standard blasting practice. Where special circumstances demand a larger number of standard delay periods, always contact a Dyno Nobel representative for specific recommendations before planning the blast design.

• NEVER use electric detonators near radio frequency transmitters unless in accordance with IME SLP 20.
