Quarry Drilling Rigs: Integrated DTH for Production and Slope Holes
Quarries need rigs that move, drill fast and keep the air onboard — the integrated DTH line is built for quarry cycles.
1. What quarry drilling looks like
Quarry bench blasting typically runs 76-190 mm holes at 21-25 m depths in medium-hard rock. Production is measured in holes per shift, so mobility between benches and fast hole cycles matter as much as raw capacity.
2. Why integrated rigs fit quarries
Integrated DTH rigs (KT5C, KT9C, KT15i, KT30) carry the screw compressor onboard — one machine, one operator, no compressor fleet to manage. For a single-rig quarry that moves between benches weekly, integrated wins on logistics.
Compact integrated rigs (KZ5, KZ9) suit smaller quarries at 90-165 mm holes with easy relocation; the KT range covers the full 76-190 mm quarry spectrum.
3. Split rigs for multi-rig sites
Quarries running several rigs or varying hole sizes across pits can right-size a KSCY compressor fleet with split rigs (KG420B, KG520) — one compressor feeds multiple rigs and matches the hammer in use.

| Hole range | Rig class | Reference models |
|---|---|---|
| 76-115 mm | Compact integrated DTH | KT5C, KT5H, KZ5 |
| 90-165 mm | Integrated DTH | KT9C, KT9D, KZ9 |
| 115-190 mm | Large integrated DTH | KT15i, KT25, KT30 |
| 90-130 mm, existing compressor fleet | Split DTH | KG420B, KG520 |
Frequently asked questions
Integrated or split for a single-rig quarry?
Integrated. One machine carries its own compressor and mobilises fastest between benches — the standard answer for 1-2 rig quarry operations.
What hole diameter do most quarries drill?
Production benches commonly run 90-165 mm; larger aggregate and limestone operations go to 190 mm with the KT30.

Open-pit Mining
Hole diameter, bench depth and rock hardness drive the rig choice — here is the selection logic for blast-hole drilling in open-pit mines.
Water Well
The chassis decision drives half the operating cost of a water-well business — pick by terrain, transport distance, well depth and hole diameter.
Deep Water Well
Deep wells change the air equation — pressure climbs, flow must hold, and the compressor becomes the bottleneck.
Geothermal
Configure the drilling rig, high-pressure compressor and DTH tooling for deep geothermal wells in hard-rock formations.
Remote Area
Off-grid sites reward equipment that brings its own power, air and parts — diesel-driven rigs and compressors are the remote-site standard.
High-altitude
Above 3000 m, thin air derates engines and compressors — equipment must be configured for altitude, not just delivered.
