Blast Hole Projection

KwikMark - Mining Equipment in South Africa

KWIKSPOT is a projector fitted with a precision drilled patented metal graticule (drill pattern) which projects on the rock face the required drill pattern for tunnel sizes ranging from 10m2 to 48m2.

This extremely robust but lightweight projector, powered by a 1 x LI-ION 3.7 V rechargeable battery and using a high end power LED, is mounted on a standard surveyor's tripod 8 to 10 metres from the rock face, approximately 1.5 to 2.5 metres above the footwall and more or less in the middle of the tunnel.

A tilt head enables the projector to be quickly and accurately levelled and directed at the rock face.

DRILL PATTERN (Gradicule) (Patent No F2013/01100)

The drill pattern is focused through a zoom lens which increases or decreases the distance between the hole spacing until the correct distance between the holes are achieved. The centre line and grade lines are included in the drill pattern.

The marking and drilling of the drill pattern can then proceed with speed and repeatable consistency.

The drill pattern can be rotated 180 degrees. This enables the "cut" to be projected on the opposite side of the rock face to be marked.

Note: All the holes will still be in the same position as before.
