GST SQD DRILL RIG

The SQD drill rig is manufactured as a Pneumatic or a Hydraulic drill rig. The rig is used to drill, support and blast holes at the development end. Thus, with the rollover assembly, the rig can drill in any direction. At GST, we aim to make our drill rigs safe, accurate and effective. Accordingly, SQD stands for ‘Safe, Quality, Drilling’.

Safety

Operator safety – more than four metres from the face with the operator situated under a canopy.
The operator is always under permanent support (roof bolts) while drilling the face.
Drilling discipline; creating a safe and stable rock wall condition for rest of the development crew. (Minimise damage to hang wall conditions).
Safer drilling method in poor ground conditions.

Quality

Improved cost-efficiency
Controlled drilling reduces support and secondary support cost.
Improves advance per blast due to drilling discipline.
Reduces explosive cost because of increased face advance and reduces the number of holes.
Increases development rate as longer rounds can be drilled; for example, 3.8-metre rounds have been drilled successfully.
Favourable unit cost with better face advance compared to handheld drilling.

Drilling

Roof bolts drilled remotely.
Physical working conditions become more favourable and acceptable.
Enhances skills development.
Drilling time is decreased due to double booms capable of working independently.
