Product Features & Advantages

Dual-Support & Multi-Functional Capability

Unlike single-function drilling equipment, the CMM2 15Y mine drilling equipment achieves simultaneous roof and rock support—reducing roadway reinforcement time by 40% compared to traditional single-support drills. It also integrates water/gas detection hole drilling, eliminating the need for separate equipment and cutting operational costs by 25%.

High-Precision Hydraulic System

• Variable hydraulic pressure control matches drilling force to rock hardness (f=3~8), minimizing drill bit wear and breakage rate by 55%.
• Smooth hydraulic operation ensures hole positioning accuracy within ±0.5cm, enhancing anchor rod stability and reducing rock fall risks.
• Energy-efficient hydraulic components cut power consumption by 18% vs. industry average for hydraulic anchor drill for coal mines.

Compact & Slope-Resistant Design

The drilling vehicle for coal mine applications features a streamlined frame (1700mm width) that navigates 4.5m-wide roadways with ease, while its anti-slip track and weight-balanced design ensure stable operation on ±18° slopes—addressing the pain point of equipment instability on inclined mine roadways.

Comprehensive Safety Features

• Explosion-proof electrical system (Ex ia I Mb certification) prevents ignition of flammable gas in underground mines.
• Emergency stop buttons (both on-board and remote) trigger instant shutdown in hazardous situations, protecting operators.
• Dust suppression system reduces airborne particles by 70%, improving underground air quality and operator health.

Operating Steps

1. Pre-Operation Inspection: Check hydraulic oil level, electrical connections, drill bit wear, and track condition; verify remote control signal (range up to 300m) and explosion-proof status.
2. Positioning & Stabilization: Drive the drilling vehicle for coal mine applications to the target face, adjust the drill arm angle, and lock the anti-slip track to ensure stability (critical for slope operation).
3. Parameter Setting: Set drilling depth, pressure, and speed based on rock hardness (f=3~8) via the control panel; select mode (anchor rod support or detection hole drilling).
4. Drilling Operation: Start drilling via on-board or remote control; monitor real-time pressure and depth to avoid overloading the hydraulic system.
5. Support Installation/Detection: For anchor rod support—insert and secure rods after drilling; for detection holes—collect water/gas samples and record data.
6. Post-Operation Reset: Retract the drill arm, clean the drill bit, and move the vehicle to the next position; conduct a quick inspection for leaks or damage.
7. Routine Maintenance: Lubricate moving parts, drain hydraulic system contaminants, and log operation data for maintenance tracking.

Application Scenarios

• Primary: Roof/rock simultaneous support operations in coal/semi-coal rock roadway excavation faces (width ≤4.5m, height ≤4.0m).
• Water/gas detection hole drilling in coal/rock layers with hardness f=3~8 (critical for mine safety monitoring).
• Reinforcement of inclined roadways (±18° slope) in medium-to-small coal mines.
• Maintenance and repair of existing mine tunnel structures (wall/roof stabilization).
• Emergency support operations in areas with potential rock fall risks (fast deployment via compact design).

Benefits for Customers

• Enhanced Operational Efficiency: Dual-support capability allows the CMM2 15Y mine drilling equipment to complete 25+ anchor rod installations per hour (3x faster than manual operations), cutting roadway support time by 40%.
• Reduced Labor Costs: Requires only 1 operator (vs. 2-3 for traditional drills), lowering annual labor expenses by 50% for mining enterprises.
• Improved Safety: Remote operation and explosion-proof design reduce operator exposure to hazards, cutting accident risks by 65% in underground work.
• Lower Equipment Costs: Multi-functional design (support + detection) eliminates the need for separate drilling equipment, reducing capital expenditure by 30%.

Production Process & Quality Control

Core Production Steps

1. Raw material inspection (high-strength steel, hydraulic components) with third-party quality verification.
2. CNC machining of key components (drill arm, frame) with precision tolerance of ±0.1mm.
3. Welding and anti-corrosion coating (epoxy resin + anti-rust paint) to withstand underground humidity.
4. Hydraulic system assembly and 24-hour pressure stability testing.
5. Explosion-proof electrical system installation and certification testing.
6. Whole machine commissioning (simulated slope operation for 48 hours) to verify performance.

Strict Quality Control

Every drilling vehicle for coal mine applications undergoes 10 quality checkpoints before delivery, including hydraulic pressure testing, slope stability verification, and explosion-proof performance audits—ensuring a defect rate of less than 0.15% and consistent performance in harsh underground conditions.

FAQ (Frequently Asked Questions)

Q1: Can the CMM2-15Y operate in rock layers harder than f=8?

A: The standard model is optimized for f=3~8, but we can customize the hydraulic system and drill bit to handle rock hardness up to f=10 (additional cost applies). This makes the hydraulic anchor drill for coal mines adaptable to more complex geological conditions.

Q2: What is the maintenance frequency and cost for the CMM2-15Y?

A: Routine maintenance is required every 250 operating hours (oil/filter replacement) at a cost of ~$180 per service. Major maintenance is only needed every 2 years (~$1,800), which is 30% lower than industry averages for comparable drilling vehicle for coal mine applications.

Q3: Is the CMM2-15Y compatible with our existing mine power supply (380V)?

A: The standard model uses 660V/1140V (mine-specific), but we can customize the electrical system to 380V for above-ground or non-explosion-proof applications. We also provide on-site wiring guidance to ensure seamless integration with your infrastructure.
