Separating rock from the natural bedrock demands precision drilling. The two key techniques in dimensional stone quarrying, smooth blasting and diamond wire sawing.
Both demand effective drilling in order to produce saleable blocks. Boreholes for dimensional stone must be absolutely straight and clean.
Dimensional Stone techniques
Typical drilling applications are line drilling, splitting, squaring, pilot hole drilling, slot drilling and development drilling.
These are the four main phases of the process:
1. Primary block is extracted from the bench
2. Loosened block is subdivided to smaller blocks to be dipped
3. Secondary block is divided to transportable blocks
4. Blocks are trimmed to final shape
Before a diamond wire saw can be used, matching vertical and horizontal pilot holes must be drilled for the wire.
