Technical Specifications

Why Your Coal Mining Project Needs Our PDC Bits?

Coal mining environments present unique challenges. You face abrasive rock layers, unpredictable formations, and demanding production schedules. Our product addresses these challenges head-on.

Superior Wear Resistance

Your drilling operations can't afford frequent bit changes. Our matrix body construction withstands extreme abrasion, keeping your crew productive longer. The carefully engineered PDC cutter layout maximizes contact efficiency while distributing wear evenly across the bit face.

Exceptional Rate of Penetration

Time is money in coal mining. Our bits cut through hard and medium-hard formations efficiently, reducing your cost per meter drilled. You'll complete boreholes faster, allowing your operation to maintain aggressive production targets.

Built for Tough Conditions

Whether you're drilling roof bolt holes, conducting geological exploration, or performing gas drainage operations, these bits handle it all. The robust matrix design resists impact damage while maintaining gauge integrity throughout the bit's operational life.

Key Applications Across Mining Operations

Coal Mining

You need consistent performance for roof bolting, roadway development, and production drilling. Our bits maintain gauge diameter and deliver predictable penetration rates shift after shift.

Mining Exploration & Probing

When you're investigating new seams or mapping geological structures, accurate boreholes matter. Our bits provide stable drilling with minimal deviation, giving you reliable geological data.

Gas Drainage Operations

Safety depends on effective gas drainage systems. Our Matrix PDC Bit for Coal Mine drills clean, precise holes for drainage pipe installation, supporting your mine's ventilation and safety protocols.

Geological Prospecting

Understanding your formation helps plan extraction strategies. These bits excel in exploratory drilling, cutting through varied lithology while providing core samples when needed.

What Makes Our Matrix Design Different?

You deserve drilling tools engineered with precision. Our technical team analyzes your specific geological conditions before recommending bit configurations. We consider rock hardness, brittleness, clay content, and formation characteristics.

The matrix body incorporates tungsten carbide particles bonded under high temperature and pressure. This creates a bit body that's nearly as hard as the formation itself, dramatically reducing body wear.

PDC cutter placement follows advanced hydraulic modeling. This ensures optimal chip evacuation and cooling, preventing bit balling and maintaining consistent cutting action.

Optimizing Your Drilling Performance

Getting most extreme esteem from your boring devices requires legitimate parameter choice. Here's what you ought to consider:

For Delicate to Medium Formations

Increase your weight on bit and rotational speed. The PDC cutters will shear through milder fabric productively, maximizing your infiltration rate.

For Difficult Shake Conditions

Reduce rotational speed whereas keeping up direct weight on bit. Guarantee satisfactory pump yield to evacuate cuttings and cool the bit confront. This approach lets the PDC cutters smash and break difficult shake without intemperate wear.

Monitor Execution Continuously

Watch for changes in penetrating behavior. Sudden vibration or diminished entrance regularly signals bit wear or arrangement changes. Assess your bit routinely to capture issues some time recently they affect productivity.

Maintenance Best Practices

Your venture merits appropriate care. After each boring operation, clean the bit completely. Expel all arrangement flotsam and jetsam and review the lattice body for splits or damage.

Check PDC cutter condition carefully. When cutters wear down to less than 1/5 of their unique volume, substitution gets to be vital. Proceeding to bore with unreasonably worn cutters harms the bit body and diminishes productivity dramatically.

Gauge wear requires consideration as well. If gage assurance strips wear more than 2/3 of their thickness, supplant the bit or restore the gage segment. Worn gage increments borehole breadth irregularity and quickens bore string wear.

FAQ

Q: What information should I provide before purchasing to ensure I choose the right PDC bit for my needs?

A: To help our team recommend the most suitable PDC bit, please provide the following information:

① Hardness coefficient (F-value or drillability grade) or lithology of the target rock formation;

② Expected borehole diameter and depth;

③ Drill rig model and key operating parameters (rotational speed, torque, pump output, etc.);

④ Application scenario (e.g., roof bolting, gas drainage, geological exploration);

⑤ Any special requirements (e.g., complex formations, fractured zones, hard interlayers).

Once we receive this information, our technical team will offer professional selection advice and free technical support. Custom manufacturing is also available.

Q: What advantages do PDC bits have over tungsten carbide bits?

A: Take the two-wing PDC roof bolt bit as an example. Under identical rock conditions, its service life is 10 to 30 times longer than that of a tungsten carbide bit, and drilling efficiency is at least 60% higher. Additionally, PDC bits do not require resharpening, which significantly reduces labor intensity and saves rig time. Industry data shows that PDC bits typically last more than 10 times longer than tungsten carbide bits.

Q: What maintenance should be performed after each drilling operation?

A: After each drilling operation, clean the bit body promptly. Carefully check for any abnormalities, such as matrix detachment or cracking of the steel body. Also inspect the wear condition of the PDC cutters.

If the gauge protection strip is worn by more than 2/3 of its original thickness, continued use will severely reduce drilling efficiency and accelerate wear on the core barrel and drill pipe. In that case, replace the bit or have the alloy re-welded.

When less than 1/5 of the PDC cutter volume remains, do not continue using the bit – replace the PDC cutters immediately.

Q: Drilling speed is unsatisfactory. How can I optimize drilling parameters based on rock conditions?

A: Rate of penetration depends closely on rock hardness, density, and abrasiveness.

①For soft to medium-hard formations, increase weight on bit and rotational speed appropriately.

②For hard rock formations, use a lower rotational speed, moderate weight on bit, and sufficient pump output to fully utilize the shearing and crushing action of the PDC cutters.

Each bit size has a recommended range of operating parameters – refer to the product data sheet for details. As a general rule, adjust parameters based on penetration feedback. If you encounter abnormal vibration or a sudden drop in penetration rate, pull the bit out for inspection.

Q: How can I tell the difference between normal wear and abnormal damage of a bit?

A: Bit failure typically appears as diamond layer spalling, chipped cutters, lost cutters, or erosion of the cutter studs.

Normal wear usually shows as uniform consumption of the diamond layer, with the cutting edge becoming dull but not chipped. This can be addressed by manual conditioning of the bit or by replacing the PDC cutters.

Abnormal damage includes premature separation of the diamond layer from the tungsten carbide substrate, overall fracture of the diamond layer, or weld failure. These issues are often caused by sudden changes in formation or improper handling.

To reduce the risk of abnormal damage, operators should select a PDC bit that matches the performance of their drill rig, maintain stable weight on bit and rotational speed while drilling, and avoid heavy impacts as much as possible.
