Industrial Hydraulic Drilling Rigs for Water Well and Mining Applications

CNMAC manufactures crawler-mounted and truck-mounted hydraulic drilling rigs engineered for water well excavation, geothermal exploration, quarry blast hole drilling, and rock anchoring. Driven by turbocharged diesel engines and heavy-duty hydraulic top-head drive units, these rigs operate with high-pressure DTH hammers and rotary drilling bits across rock formations up to hardness ratings of f=20.

Applications

Water Well and Irrigation Drilling

Penetrating clay, gravel, and solid bedrock layers to establish domestic, industrial, and agricultural groundwater supply wells.

Geothermal Borehole Drilling

Drilling deep ground-loop heat pump boreholes with consistent hole diameter straightness.

Mining and Quarry Operations

Cutting production blast holes and presplit holes in granite, limestone, and iron ore formations.

Geotechnical Engineering

Installing tieback anchors, micro-piles, and grouting holes for slope stabilization and foundation reinforcement.

Configuration and Customization Options

Power and Emission Options: Cummins, Yuchai, or Deutz diesel engines compliant with Tier 2, Tier 3, or Stage V regulations. High-altitude turbochargers available for elevations above 3,000 meters.

Chassis Configurations: Steel crawler tracks with rubber pads for paved roads, or truck-mounted chassis options for rapid inter-site highway transport.

Drilling Attachments and Tools:
DTH Hammers (3 inch, 4 inch, 5 inch, 6 inch sizes)
Carbide Button Bits (Spherical, Ballistic, and Flat Face profiles)
Threaded Drill Rods (API 2 3/8 inch REG, API 3 1/2 inch REG connection standard)

Mud Pump Systems (BW-160 / BW-250 piston pumps for mud circulation) Auxiliary Equipment: Hydraulic winch assemblies, automatic rod-handling carousels, dual-stage foam pumps, and night-operation LED work lights.

Quality Assurance and Structural Compliance

Mast Integrity

The structural drilling mast is fabricated from high-strength manganese steel channels, undergoing stress-relieving heat treatment and magnetic particle testing (MT) on key load welds.

Hydraulic System Protection

Dual multi-stage return line filtration (10-micron nominal) combined with sealed oil reservoir breathers prevents silica dust contamination in hydraulic pumps and control valves.

Factory Testing Protocol

Every rig undergoes a full-function test before shipment, including 2.5 MPa pressure holding on hydraulic lines, winch load tests, and rotation torque verification.

Manufacturing Standards

Manufactured in ISO 9001-certified facilities; CE documentation available upon request.

FAQ

Q: What air compressor capacity is required to operate these DTH drilling rigs?

A: Operating requirements depend on the hole diameter and DTH hammer size. A 200m rig operating a 4-inch or 5-inch DTH hammer typically requires a diesel portable air compressor delivering 17 to 21 m3/min at 1.8 to 2.1 MPa.

Q: Can these drilling rigs switch between DTH air drilling and mud circulation drilling?

A: Yes. The head drive system features standard swivel connections that accept both high-pressure compressed air and drilling mud slurry from an external mud pump (such as a BW-160 pump) for soft soil or collapsible sand formations.

Q: Are the drill rod threads compatible with international API standards?

A: All drill rods, top-head adaptors, and DTH hammer sub-adapters are machined with standard API thread profiles (API 2 3/8 inch REG or API 3 1/2 inch REG), allowing full interchangeability with third-party drilling tools.

Q: How does the hydraulic system perform under high dust and high ambient temperature conditions?

A: The system utilizes large-capacity aluminum hydraulic oil radiators with temperature-controlled cooling fans. Hydraulic tanks feature sealed filling caps and dual suction/return filtration units to keep dust out during continuous dry rock drilling.

Q: How are the rigs packed for containerized ocean shipping?

A: Models HQ150 and HQ200 fit into standard 40HQ shipping containers after lowering the mast and removing the track shoes or side stabilizers. Reassembly on site requires securing 4 to 6 main hinge bolts and connecting labeled quick-coupling hydraulic hoses.

Q: What is the production lead time for customized orders?

A: Standard models are produced within 20 to 25 working days. Custom configurations, such as specialized truck chassis mountings, specific engine emission packages, or custom color schemes, take 30 to 35 working days.
