QUARRY ENGINEERING

The Quarry Conditions We Solve

Quarry drilling must deliver repeatable blast holes across changing benches. Rock hardness, fracture patterns, dust, hole deviation and compressor output directly affect productivity and aggregate quality.

01

Variable Bench Geology

Maintain predictable drilling as the bench moves between weathered zones, fractures and competent hard rock.

02

Uneven Penetration Rate

Balance impact energy, feed, rotation and flushing to reduce slow holes and production variability.

03

Premature Consumable Wear

Match bit face, carbide profile and operating pressure to abrasiveness and the required hole diameter.

04

Hole Pattern Accuracy

Control collar position, depth and deviation so the completed pattern supports consistent blasting results.

PRODUCTION-LED TOOL SELECTION

A Practical Configuration for Quarry Blast Holes

HLDRILLS reviews the bench formation, hole diameter, depth, pattern and daily metre target before matching the bit and hammer family to the drill rig and compressor.

The objective is stable production across the full pattern, with controlled wear and fewer interruptions for tool changes.

Recommended Configuration Logic

Final specifications are confirmed after working-condition review.

  • Bench: rock type, hardness, abrasiveness, fractures and weathering
  • Hole: diameter, depth, inclination and blast-pattern tolerance
  • Air system: pressure, volume, dust control and flushing demand
  • Tooling: hammer series, shank, face design and carbide profile
  • Operation: feed, rotation, collaring method and maintenance interval

QUARRY ENGINEERING

From Bench Data to Repeatable Production

A clear four-step workflow reduces tool-selection risk before full-pattern deployment.

STEP 01

Bench Review

Collect rock, hole, pattern, rig, compressor and current consumable-performance information.

STEP 02

Tool Matching

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

STEP 03

Trial & Parameter Setup

Confirm collaring, feed, rotation and flushing on a controlled group of quarry holes.

STEP 04

Pattern Performance Review

Compare penetration, deviation and wear across the pattern, then refine the configuration.
