This series of drilling rigs is used for constructing gas extraction holes, water exploration and drainage holes, pressure relief holes, and other engineering boreholes in narrow roadways during underground coal mine drilling operations. The machine features a compact structure with a width of less than 850 mm and is equipped with a fully hydraulic control system and a remote-controlled moving system, enabling flexible movement and safe operations in narrow roadways and adapting to confined working environments. The manual swing-out type stabilizing cylinders are provided to increase the width of the vehicle, ensuring overall machine stability during drilling. The modular structure facilitates transportation, installation, and maintenance, reducing downtime and improving equipment utilization.
