Kwikspot
Blast Hole Projection
KWIKSPOT is a projector along the lines of a slide projector but instead of using a photographic slide, it uses a metal graticule drilled by means of a computerised machine center. The complete drill pattern is drilled on the gradicule (up to 150 holes) which is suitable for tunnel sizes ranging from 10m2 to 48 m2. The light source is a 12 volt 75 watt Halogen Lamp.
Focusing of the drill pattern is done through a zoom lens which can increase or decrease the distance between hole spacing until correct focusing is achieved. Other marks such as center line and grade lines can also be included. The projector is placed on a surveyor type tripod. A tilt head enables the projector to be leveled and directed at the rock face.
The projector is normally placed 8 to 10 metres from the face, approximately 1,5 to 2,5 metres above the footwall and more or less in the center of the tunnel. The light dots that appear on the tunnel face are 50 mm in diameter. The power source is a 12 volt 18 AMP battery.
