Crawler Drilling Rig

Underground drilling rig solution: Achieving high efficiency, low energy consumption and precise hole formation for large-diameter drilling

I. Solution Background and Market Pain Points

In operations such as mining, construction engineering, well drilling, tunnel anchor bolt holes, etc., the following problems are commonly encountered:

The rock is hard, making the drilling process slow and the construction period long.

The drilling is highly skewed and the wall quality of the hole is poor, which affects the blasting or subsequent processes.

High fuel consumption, short lifespan of the impactor and drill bit, and persistently high operating costs.

The site was severely contaminated with dust, which not only polluted the environment but also affected the visibility of equipment and the health of personnel.

In response to these challenges, we have launched a full range of down the hole drilling rig solutions, centered around "high-pressure impact + stable advancement + dust collection and environmental protection", to help customers achieve fast, accurate, cost-effective and clean drilling operations.

II. Core Technology Composition

1. High-pressure Submersible Impact System

Utilizes high-power high-pressure air compressors or external air sources, with wind pressure reaching 1.5–2.5 MPa

Matched with a DTH impactor that has low gas consumption and high impact energy, it is suitable for hard rock with grades f = 6 - 20.

The impact frequency is intelligently matched with the propulsion speed, reducing the occurrence of stuck drill bits and wasted efforts.

2. Robust propulsion and rotation mechanisms

Dual-motor rotary power head, with high torque and adjustable rotational speed in steps.

Propulsion cylinder + chain/synthetic rope mechanism, ensuring smooth propulsion and preventing the drill from deviating.

Heavy-duty guide rails and reinforced chassis ensure the overall stability of the machine for large-diameter drilling operations.

3. Efficient Dust Collection System (optional or standard)

Dry type: Two-stage cyclone + filter cartridge dust collection, dust collection rate ≥ 95%

Wet type: Water injection for dust suppression, suitable for areas with high dust sensitivity.

Reduce on-site dust, meet environmental protection requirements, and extend the lifespan of air filters and engines

4. Intelligent Control and Ergonomics

Centralized electrical control/hydraulic control console, one-click leveling, automatic anti-stuck drill function.

The numbers display parameters such as depth, pressure, and rotational speed.

Optional remote control or automatic angle positioning, suitable for complex terrains.

III. Application Scenarios and Recommended Configurations

The above parameters are based on conventional hard rock conditions. The actual configuration can be customized according to the hardness of the rock and the altitude.

V. Typical Case Reference

A Large-scale Limestone Mine

Rock hardness: f = 10–14

Requirement: Diameter φ115mm, total excavation length per shift ≥ 200 meters, with low failure rate required.

Solution: Equip with a diesel-powered integrated submersible drilling rig, with a wind pressure of 2.2 MPa, an impactor of type SD12, and a dry dust collection system.

Effect: The average daily progress length was 220-240 meters, the deviation rate was less than 1.5%, the dust collection efficiency was 97%, the operators were satisfied and requested an additional 2 units.
