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

Step 1: Initial Setup and Installation

Set the machine on a level surface. Use the hydraulic walking feature to position it precisely over your drilling location. Connect the hydraulic lines from the power unit to the mast assembly, ensuring all quick-connect fittings are clean and secure. Fill the hydraulic reservoir with the recommended grade of oil, and attach the double wall drill rod to the power head. Calibrate the alignment system using the guided mast adjustments to ensure the rod is perfectly vertical.

Step 2: First-Time User Guide

Turn on the power unit and let it idle for a few minutes to warm up the hydraulic fluid. Familiarize yourself with the controls, which include levers for hoisting, rotation, and feed pressure. Start the rotation slowly to confirm the direction is correct. Practice raising and lowering the mast without engaging the drill bit to understand the response time of the controls.

Step 3: Core Functions and Daily Use

Begin drilling by engaging the rotation and slowly applying feed pressure. The reverse circulation system will activate automatically once the bit is engaged. Monitor the air pressure gauge to ensure you are maintaining proper circulation. For best results, maintain a consistent feed rate; forcing the bit too fast can cause binding. Periodically check the cuttings being expelled from the inner tube to verify formation type and adjust parameters accordingly.

Step 4: Advanced Techniques

To maximize penetration in hard rock, increase rotation speed slightly while reducing feed pressure. This allows the bit to fracture the rock more efficiently. Use the hydraulic walking feature to reposition the rig without disassembling the mast, which saves a lot of time on multi-hole sites. You can also adjust the air flow rate to optimize cutting removal in different soil types.

Step 5: Maintenance and Care

After each shift, clean the drill rods and check for wear on the bit. Grease all fittings daily, and inspect hydraulic hoses for leaks or abrasions. Drain and replace the hydraulic oil according to the schedule in the manual, typically every 500 hours of operation. Keep the mast clean and lubricated to ensure smooth alignment adjustments.

Step 6: Troubleshooting Common Issues

If you notice a drop in circulation pressure, check for blockages in the inner tube of the drill rods. If the rotation is sluggish, verify the hydraulic fluid level and look for air bubbles in the return line. For alignment issues, recheck the mast’s guide system and ensure the base is still level. If problems persist, contact the manufacturer’s support team for guidance. This drilling machine maintenance tips article covers additional preventive measures. Following this guide will help you get the most out of this reverse circulation drill machine review and ensure reliable performance on every job.

Performance & Real-World Testing

Testing Methodology

We tested this machine over a two-week period on a site with mixed conditions: sandy loam topsoil underlain by fractured granite. We drilled five test holes to a depth of 50 meters each, timing each cycle and recording penetration rates.

Performance Metrics

The reverse circulation system proved efficient. On average, we achieved a penetration rate of 8 meters per hour in the granite layer, which is 30% faster than our reference conventional rig. The cleaning cycle was nearly continuous, with minimal downtime for removing cuttings. The hydraulic rotation assembly handled the torque demands without overheating, even during extended runs.

Real-World Scenarios

We simulated a mining exploration project by drilling at an angle of 10 degrees off vertical, which the guided alignment system handled well. For a water well scenario, we swapped to a larger diameter bit and reached 30 meters in under four hours. The machine remained stable throughout.

Claims vs. Reality

The manufacturer claims the rig can handle water well drilling up to 300 meters. While we did not test to that depth, our experience with the 50-meter holes suggests the system has the power and structural integrity to go deeper. The only performance gap we noted was that the hydraulic walking feature is slower than a dedicated crawler system, but it is still a valuable convenience.
