Ballistic Discs - for breaking up hang ups and upstanding rill in underground hard rock mines. Ballistic Discs provide a safe and effective way of remotely clearing hang ups and upstanding rill in draw points and stopes. When detonated a ballistic disc produces a large steel slug that is propelled at hypersonic velocity (2000-2600 m/s). The kinetic energy transferred on impact, up to 60 MegaJoules which shatters the target area. Medium & large focal charges - for secondary rock breakage. Focal Charges are designed for secondary rock breakage. Focal Charge is more efficient than an equivalent mass plaster charge, and does not require mud-capping. Focal Charge may be rapidly deployed as it does not require any holes to be drilled in the target boulder.

Large Hemispherical Shaped Charges - for explosively generating a borehole, or clearing draw points.

Hemispherical Shaped Charge provides a rapid and effective way of explosively generating a borehole, or clearing draw points where drill/blast or bombing is ineffective. When detonated, the HSC produces a penetrating jet and large steel slug propelled at high velocity in the direction aimed. Fractures and penetration in rock due to jet and blast are caused by compression, tension and shear failure.

Small Hemispherical Shaped Charges - for unblocking blast-holes and clearing steel reinforcing within drill holes. When detonated the HSC produces a penetrating jet and broad form slug into the presented obstacle. The penetrating jet, travelling at approx 5000 mtr/sec induces the contact area of the obstacle to behave in a hydrodynamic fashion. The adjoining slug delivers kinetic shock energy.

SEVERANCE CHARGES, UNDERWATER FOCUS CHARGES wellhead severance charges and underwater focussed cutting charges for cutting plate, tubular members and mooring components. Focussed, or shaped charges, produce a more reliable and cleaner cut, with a lower explosive loading than alternative explosive methods
