MINING DRILLING

The Mining Conditions We Solve

Open-pit and underground mines need more than a standard bit. Rock strength, abrasiveness, fractured zones, hole diameter and compressor output all affect penetration rate and tool life.

01

Hard & Abrasive Formations

Maintain reliable penetration in iron ore, gold-bearing hard rock and other high-compressive-strength formations.

02

Premature Bit Wear

Match face design, carbide profile and operating pressure to reduce abnormal wear and unplanned tool changes.

03

Unstable Drilling Efficiency

Balance impact energy, flushing and rotation parameters for repeatable metres per shift across changing benches.

04

Rig-Tool Compatibility

Confirm shank, hammer, hole diameter, air pressure and drill-rig capability before the tools reach site.

FORMATION-LED TOOL SELECTION

A Practical Configuration for Mining Blast Holes

HLDRILLS starts with the formation and the drilling system. For high-pressure DTH applications, we align the bit diameter and shank with hammer series, compressor capacity and the mine target penetration rate.

The objective is not simply faster drilling. It is stable metres per shift, controlled wear and a lower total cost per drilled metre.

Recommended Configuration Logic

Final specifications are confirmed after working-condition review.

  • Formation: hardness, abrasiveness, fracture and water conditions
  • Hole: target diameter, depth, deviation tolerance and bench plan
  • Air system: compressor pressure, volume and flushing demand
  • Tooling: DTH hammer series, matching shank and bit face design
  • Operation: rotation speed, feed pressure and maintenance cycle

MINING DRILLING

From Formation Data to Field Performance

A clear four-step workflow reduces selection risk before bulk deployment.

STEP 01

Working-Condition Review

Collect formation, diameter, depth, rig, compressor and current tool-life information.

STEP 02

Tool Matching

Select the hammer family, shank, bit diameter, face profile and carbide configuration.

STEP 03

Trial & Parameter Setup

Confirm operating parameters through sample testing or a controlled trial order.

STEP 04

Performance Optimization

Review penetration, wear pattern and cost per metre, then refine the configuration.
