How to Use Reverse Circulation Drill Machine for Mining Exploration and Deep Borehole Construction Applications: Complete Guide

Getting this rig operational requires some upfront effort, but the process is straightforward if you follow these steps. We will walk you through setup, basic use, and maintenance to get the most out of your deep borehole drilling machine worth buying.

Step 1: Initial Setup and Installation

Start by placing the machine on level ground. Extend the hydraulic stabilizers until the frame is fully supported and does not rock. Connect the 220V power supply to the control panel. Attach the hydraulic hoses from the pump to the mast cylinders. Check all connections for tightness. Finally, insert the first double wall rod section into the power head chuck and secure it with the locking pins.

Step 2: First-Time User Guide

Power on the control panel. You will see indicator lights for hydraulic pressure and rotation speed. Set the rotation to low for the first few meters to allow the bit to seat into the formation. Adjust the feed rate using the hydraulic lever. Do not force the bit. Let the weight of the rod string do the work. This initial run helps you understand how the machine responds to different ground conditions.

Step 3: Core Functions and Daily Use

For regular operation, set the rotation speed between 30-50 RPM depending on rock hardness. Keep the water injection system running to cool the bit and flush cuttings up the inner tube. Monitor the return air pressure gauge. A steady reading indicates proper circulation. If the pressure spikes, you might have a blockage in the rod. Stop rotation and clear the obstruction before continuing.

Step 4: Advanced Techniques

To maximize efficiency in hard rock, reduce the feed pressure slightly and increase rotation speed. This prevents bit glazing and extends bit life. Use the hydraulic walking feature to move between drilling spots without disassembling the mast. It saves at least 20 minutes per relocation on uneven ground.

Step 5: Maintenance and Care

After each shift, clean the rod threads with a wire brush and apply anti-seize compound. Inspect the hydraulic hoses for abrasion or leaks. Change the hydraulic oil every 500 hours of operation. The user manual provides a detailed schedule, but we recommend greasing the mast guide rails weekly.

Step 6: Troubleshooting Common Issues

If the bit stalls frequently, verify the rotation speed setting and reduce feed pressure. For low return airflow, check the seals on the double wall rods for wear. A persistent hydraulic leak points to a worn hose or connection. Replace immediately. If the control panel shows error codes, consult the troubleshooting chart in the manual. For serious mechanical issues, contact the support line.

Expert Tips for Maximum Value

Here are actionable tips to get the most out of your investment.

Tip #1: Optimize Rotation Speed

Do not run the bit at maximum rotation all the time. Match the RPM to the formation. Slower for hard rock, faster for soft sediment. It saves wear on the bit and reduces fuel consumption.

Tip #2: Schedule Regular Greasing

Grease the mast guide rails every 10 hours of operation. It prevents uneven wear and keeps the feed mechanism smooth. A small habit that extends the life of the machine significantly.

Tip #3: Use a Particle Separator

Add a cyclone or shaker at the surface to separate cuttings from the return air. This improves sample quality and reduces the load on your dust control system. We recommend picking up a portable shaker unit for this purpose.

Tip #4: Pre-Drill Pilot Holes

For very deep holes, drill a pilot section with a smaller diameter bit first. This reduces the torque load on the main string and helps maintain straightness.

Tip #5: Monitor Hydraulic Oil Temperature

Install an external thermometer on the hydraulic reservoir. If oil temperature exceeds 80 degrees Celsius during operation, stop and let it cool. Overheating accelerates pump wear.

Tip #6: Buy Extra Rods Upfront

Order additional double wall rods when you purchase the machine. Matching rod sets from the same manufacturing batch reduce thread mating issues and vibration.

Tip #7: Use the Walking System Strategically

Plan your drilling pattern before you start. The hydraulic walking feature can move the machine diagonally, but it is fastest on straight lines. Map out your borehole locations to minimize repositioning turns.

Common Mistakes to Avoid

1. Mistake: Starting at full speed in hard rock. Solution: Begin with low rotation and feed pressure, then gradually increase as the bit settles into the formation.
2. Mistake: Skipping rod thread cleaning between connections. Solution: Always clean and lubricate threads before each coupling to prevent cross-threading and leaks.
3. Mistake: Not leveling the machine properly. Solution: Use a bubble level on the mast base. An unlevel rig causes borehole deviation and uneven wear on the hydraulic cylinders.
4. Mistake: Ignoring hydraulic fluid levels. Solution: Check the reservoir daily before starting. Low fluid leads to cavitation and pump damage.
5. Mistake: Overlooking dust management. Solution: Always connect a dust collector or water injection system. Excessive dust damages the rod seals and contaminates the work area.
