UNDERGROUND EXPLOSIVES PRODUCTS
JOHNEX MIGHTY ATOM is a high density 75g supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. The JOHNEX MIGHTY ATOM provides directional firing with 4 times the detonation pressure of cartridged emulsion.
JOHNEX MAGAZINE AND CARRY BOXES provide safe storage and road transportation for explosives products. Field tested and manufactured to comply to Australian Transport and Explosives Storage Standards (AS 2187)
JOHNEX ANFO is a free flowing mixture of porous prilled Ammonium Nitrate and Fuel Oil, formulated to be oxygen balanced for use in dry blastholes.
MEGADRIVE® cartridged emulsion explosives are a detonator sensitive, emulsified AN-based explosive specifically formulated for use in surface or underground rock blasting operations.
JOHNEX ECONOTRIM BUTTBUSTER is a one-piece custom length bright yellow semi rigid 21mm coiled charge designed for rapid charging of perimeter boreholes in underground tunnelling and shaft sinking.
JOHNEX MEGAPRIME is a Pentolite cast booster with a plastic protective outer shell.
JOHNEX STOPE CHARGE is a free flowing silver/grey mixture of porous prilled Ammonium Nitrate and Fuel Oil, formulated to be oxygen balanced for use in moderately wet blastholes.
JOHNEX EZICHARGE is a one-piece custom length bright yellow semi rigid 32mm diameter coiled charge designed for rapid charging of lifters, wet faces and stripping in underground tunnelling and shaft sinking.
JOHNEX EZIPRIME provides directional firing with twice the detonating pressure of cartridge emulsion.
MEGAGEL® cartridged water gel explosives are a detonator sensitive, AN-based explosive specifically formulated for use in surface or underground rock blasting operations.
JOHNEX MIGHTYPRIME® is a high density supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. JOHNEX MIGHTYPRIME® provides directional firing with four times the detonating pressure of cartridged emulsion.
JOHNEX ECHIDNA is a product retention device for all production charging applications. The semi-rigid spines flex and tighten upon insertion into a production hole, giving superior retention of both ANFO and emulsion.
JOHNEX LP DETONATORS are a series of non-electric, long period delay detonators featuring 15 delays for use in the mining industry. (25 to 9000 milliseconds) JOHNEX MS DETONATORS are a series of non electric, millisecond period delay detonators featuring 30 delays for use in the mining industry (0 to 1000 milliseconds).
JOHNEX MEGAPRIME BLADE is a high performance, easy to use alternative to traditional primers such as small diameter cartridge explosives.
JOHNEX MEGAPRIME® EDGE primers are ideal for initiating bulk ANFO
or emulsions and are compatible with 10 gram detonating cord or a
standard No 8 detonator.
JOHNEX MEGASPLIT® is a Pre-split watergel explosive presented in a continuous cartridge internally traced with detonating cord. Specifically designed for perimeter blasting in open pit applications.
JOHNEX INSTANTANEOUS ELECTRIC DETONATORS contain a priming composition of RDX base charge inside a cylindrical aluminium alloy shell, with red and grey lead wires and have been designed for use in the mining industry.
INTERDET® (inter-hole/inter-row) detonators consist of a single low strength, aluminium delay detonator, attached to a length of hollow plastic shock tube. The
detonator is housed within a colour coded plastic connector block.
MEGADET® detonators are a series of high strength non-electric detonators with millisecond delay intervals ranging from 0 ms (instantaneous) to 1000 ms.
