The crawler-mounted full hydraulic directional drilling rig produced by Puhua Energy Equipment Technology (Shandong) Co., Ltd. focuses on the core needs of complex underground coal mine environments. It can be widely used in various high-precision directional borehole construction scenarios, including gas drainage through-layer boreholes, gas drainage along-seam boreholes, water exploration and drainage boreholes, coal seam water injection, roof grouting, geological structure detection, and coal seam thickness detection. It adapts to different coal seam geological conditions and construction standards, meeting both the efficient requirements of medium-deep hole directional drilling and the precise construction needs of complex strata. It truly achieves "multi-purpose with one machine, full adaptability," greatly improving the efficiency and safety of coal mine borehole construction, and helping coal mining enterprises achieve the development goals of "mechanized substitution of manpower, automated substitution of manual labor, and intelligent unmanned operation."
As Puhua Energy Equipment's core flagship product, this crawler-mounted full hydraulic directional drilling rig is designed and manufactured in strict accordance with underground coal mine safety operation regulations, integrating advanced hydraulic technology and crawler travel design. Compared with traditional drilling equipment, it offers many outstanding advantages, fully addressing underground construction pain points. The details are as follows:
1. Integrated crawler-driven layout design – compact structure, strong controllability, stable performance, easy to move along roadways.
The crawler-mounted full hydraulic directional drilling rig developed by Puhua Energy Equipment optimizes the crawler travel mechanism in response to the narrow underground roadways and complex terrain. It provides strong traction and stable travel, allowing it to move flexibly through various underground tunnels without the need for complex transport equipment, greatly reducing the labor and time costs of equipment relocation. Meanwhile, the compact structure reduces the equipment's footprint, adapting to roadways of different widths. Even under complex geological conditions, it maintains stable operation, effectively avoiding drilling accuracy loss due to equipment vibration, and ensuring construction safety and efficiency.
2. Reliable downhole power unit – can be equipped with a hydraulic DTH hammer for rotary-percussive drilling, improving drilling efficiency.
The rig is equipped with a high-quality downhole power system that delivers stable, lasting power output, adaptable to coal and rock layers of different hardness. To address the low efficiency of drilling in hard rock, the equipment can be flexibly fitted with a hydraulic down-the-hole (DTH) hammer for rotary-percussive drilling, combining rotary drilling with impact breaking. This greatly increases drilling speed – compared to traditional drilling methods, efficiency is improved by more than 30%, effectively shortening construction cycles and reducing costs. It is particularly suitable for drilling in medium-hard coal seams and complex broken rock formations.
3. Fast and slow dual-speed control mode using a single-action control method – easy adjustment of borehole orientation to meet construction requirements.
Fully incorporating the precision needs of directional borehole construction in coal mines, Puhua Energy Equipment has designed a fast and slow dual-speed control mode for the rig. The drilling speed can be flexibly switched according to drilling depth and rock hardness, balancing efficiency and accuracy. The single-action control method is easy to operate – operators can precisely adjust the borehole orientation with simple controls, without complicated debugging. This effectively reduces operator labor intensity while ensuring that the borehole trajectory meets design requirements. It is well suited for multi-directional, multi-angle borehole construction, especially for high-precision branch boreholes.
4. High-precision wireless measurement system – uses quality components to ensure accurate trajectory measurement, enabling multi-directional branch boreholes along the designed trajectory and achieving large-area drainage.
The rig is equipped with a high-precision wireless measurement system that uses quality industry components. It provides high measurement accuracy and stable signal transmission, allowing real-time monitoring of borehole trajectory data, effectively avoiding drilling deviations caused by measurement errors, and ensuring that the actual trajectory closely matches the design plan. Relying on this system, the equipment can drill multi-directional branch boreholes along the designed trajectory, achieving large-area gas drainage and greatly improving gas extraction efficiency. This helps coal mining enterprises effectively control gas hazards. It can also be used for geological structure detection, coal seam thickness detection, and other applications, providing accurate geological data support for safe coal mine production.
It is worth mentioning that this crawler-mounted full hydraulic directional drilling rig from Puhua Energy Equipment Technology (Shandong) Co., Ltd. is an integrated medium-deep hole directional drilling rig combining the drill rig, explosion-proof computer, flow meter, and emergency stop switch. It fully considers the core requirements of explosion-proof and safe operation in underground coal mines. All electrical components comply with coal mine explosion-proof standards. The explosion-proof computer is easy to operate, displaying drilling parameters and trajectory data in real time, allowing operators to promptly understand the construction status. The flow meter precisely monitors fluid flow during drilling, ensuring that construction parameters meet requirements. The emergency stop switch provides dual protection for safe equipment operation, effectively preventing unexpected situations during construction, and comprehensively enhancing equipment safety and reliability.
The rig is suitable for both downhole motor directional drilling and surface rotary drilling construction methods. It can be paired with various drilling techniques such as hydraulic and pneumatic low‑speed motor directional drilling, adapting to different coal seam geological conditions and construction requirements with great flexibility. At the same time, the equipment can display real-time drilling trajectory data, enabling operators to adjust the borehole trajectory direction based on the displayed data, thereby accurately achieving the goal of directional drilling. This effectively solves the problems of difficult trajectory control and insufficient drilling accuracy found in traditional drilling equipment, providing strong equipment support for various directional drilling operations in coal mines.
