«ERA» Bulk Emulsion Explosives

TU U 24.6-14310112-026:2007

 

 

«ERA» EE (Application Class I ) are designed for loading dry and wet holes in open pit mining when carrying out blasting operations at ambient temperatures ranging from – 40°С to + 40ºС

 

«ERA» EE are manufactured and charged on site in special mix-pump trucks and are subsequently loaded into holes. The mixtures acquire their explosive properties after being loaded into holes (in at least 30 minutes).

 

Range of «ERA» Emulsion Explosives: 

«ERA-А» is a homogeneous mixture of emulsion and prilled ammonium nitrate

  • «ERA-Аl» is a homogeneous mixture of emulsion and prilled ammonium nitrate, aluminum powder energy additive
  • «ERA-АМ» is a mixture of «ERA-A» EE and porous ammonium nitrate, premixed with industrial oil or fuel oil

Example of Reference Designation: for «ERA-А» bulk emulsion explosives:

«ERA-A» EE: TU U 24.6-14310112-026:2007 

 

«ERA» EE are initiated by boosters:

ТГ and Т blocks or primed cartridges, authorized for this purpose, initiated by non-electric initiation systems for explosive materials (NEIS).

 

Compared with conventional explosives, «ERA» EE are:

  • TNT-free, therefore having a considerably lower content of toxic gases in products of detonation
  • low-sensitive to mechanical impact
  • producing no dust and accumulating no static electricity
  • easy to use, suitable for mechanized loading of holes
  • safe to handle
  • transportation: a mix-pump truck carries inexplosive components to the place of use of «ERA» EE.
