Here's how a typical rock drilling machine test is conducted:
✅ 1. Pre-Test Inspection
Visual check: Inspect machine body, drill boom, rods, and connections for damage.
Hydraulic system: Check fluid levels, hose integrity, and pressure stability.
Power supply: Confirm the engine or electric motor is functioning properly.
✅ 2. Test Setup
Drilling surface: Use a controlled environment like a concrete block, test tunnel wall, or actual rock face.
Rod type and bit: Equip the correct drill rod and bit (e.g., button bit for hard rock).
Measurement tools: Prepare gauges for measuring drilling speed, hole depth, and bit wear.
✅ 3. Test Parameters
Common metrics to record during the test:
| Parameter | Purpose |
|---|---|
| Penetration rate (m/min) | Drilling efficiency |
| Hole straightness | Drilling precision |
| Vibration levels | Equipment and operator safety |
| Noise level | Environmental and safety compliance |
| Dust/spray control | Safety and visibility |
| Air/water consumption | Efficiency and cost estimation |
✅ 4. Drilling Test Procedure
Start drilling at a fixed angle and speed.
Record the time to drill a specific depth (e.g., 1 or 3 meters).
Stop the machine and inspect the hole:
Diameter accuracy
Wall smoothness
Bit wear
If available, use sensors to measure torque, feed pressure, and RPM.
✅ 5. Post-Test Evaluation
Compare results with manufacturer specifications.
Analyze drill bit wear and rock fragmentation.
Make adjustments to:
Feed pressure
Rotation speed
Lubrication or flushing systems
