Product Features & Advantages

Intelligent Remote Control System

The hydraulic anchor rod drill for coal mines adopts a dual-control mode (centralized + remote) with mine Ethernet and wireless communication, enabling operators to control the drill from a safe zone—eliminating direct exposure to falling rocks, dust, and toxic gases, and reducing accident risks by 80%.

High-Performance Hydraulic System

• Stable and adjustable drilling force (0-15kN) ensures precise hole formation and reduces rod breakage rate by 60%.
• Low-noise hydraulic components (≤85dB) improve underground working environment and comply with occupational health standards.
• Energy-saving design reduces power consumption by 15% compared to traditional hydraulic drills.

Robust & Compact Structure

The CMM1 30Y underground drilling machine features a reinforced steel frame with anti-corrosion coating, resistant to impact and abrasion in harsh underground conditions. Its compact size allows easy navigation through roadways as narrow as 2m, adapting to diverse mining layouts.

Comprehensive Safety Features

• Explosion-proof electrical components (certified for coal mine use) prevent ignition of flammable gas.
• Automatic emergency stop system triggers when abnormal pressure/temperature is detected.
• Anti-slip track design ensures stability on wet/muddy underground surfaces.

Operating Steps

1. Pre-Operation Check: Inspect hydraulic oil level, electrical system, drill bit wear, and remote control signal; ensure all safety guards are in place.
2. Positioning: Drive the mine roof support drilling vehicle to the target working face, adjust the drill arm angle via remote control, and lock the track to ensure stability.
3. Drilling Setup: Install the anchor rod/cable drill bit, set drilling depth and speed parameters on the control panel.
4. Remote Drilling: Operate the drill via wireless remote control; monitor drilling pressure and progress in real-time through the centralized control screen.
5. Completion & Retraction: Stop drilling once the target depth is reached, retract the drill arm, and move the vehicle to the next working position; clean the drill bit and check equipment for wear.
6. Post-Operation Maintenance: Drain accumulated water, lubricate moving parts, and record operation data for routine maintenance tracking.

Application Scenarios

• Anchor rod/cable support operations in coal and semi-coal rock roadway excavation faces (primary application).
• Roof support drilling in deep coal mine shafts (depth >500m).
• Tunnel excavation support in coal mine auxiliary roadways (ventilation, transportation).
• Emergency roof reinforcement in areas with potential rock fall risks.
• Large-scale open-pit coal mine slope support drilling (adaptable with ground modification).

Production Process & Quality Control

Core Production Steps

1. Raw material inspection (steel plate, hydraulic components) with third-party quality testing.
2. CNC machining of key components (drill arm, frame) for precision tolerance (±0.1mm).
3. Welding and anti-corrosion coating (epoxy resin + anti-rust paint) for durability.
4. Hydraulic system assembly and pressure testing (24-hour continuous operation test).
5. Electrical system installation and explosion-proof testing.
6. Whole machine commissioning (simulated underground drilling for 72 hours).

Strict Quality Control

Each mine roof support drilling vehicle undergoes 12 quality checkpoints before delivery, including hydraulic pressure stability test, remote control signal range test (up to 500m), and explosion-proof performance verification—ensuring a defect rate of less than 0.1%.

Customer Testimonials and Reviews

FAQ (Frequently Asked Questions)

Q1: Is the CMM1-30Y compatible with our existing mining infrastructure?

A: Yes. The hydraulic anchor rod drill for coal mines is designed to integrate seamlessly with standard coal mine electrical and communication systems (Ethernet ring network, 1140V/660V power supply). We also provide on-site adaptation services to ensure compatibility.

Q2: What is the maintenance frequency and cost?

A: Routine maintenance is required every 200 operating hours (oil change, filter replacement) with a cost of approximately $200 per maintenance. Major maintenance is only needed every 2 years, with a cost of around $2,000—far lower than industry averages.

Q3: Can the drill operate in high-humidity or low-temperature underground environments?

A: Yes. The CMM1-30Y is designed to operate in humidity up to 95% and temperatures as low as -20°C. Its sealed hydraulic system and anti-condensation electrical components prevent malfunctions in extreme conditions.

Q4: What is the lead time for customized orders?

A: Standard models have a lead time of 30 days, while customized versions (e.g., extended drilling depth, special track design) take 45-60 days. We also offer expedited production for urgent orders (additional 20% fee).
