Coal Mine Crawler-Mounted Hydraulic Roadway Drilling Rig (Center-Mounted)

Product Introduction

This series of drilling rigs can be used for constructing gas extraction holes, water exploration and drainage holes, pressure relief holes, and other engineering boreholes during underground coal mine drilling operations. The machine features a compact structure with an adjustable hole-opening height, making it suitable for multi-layer drilling, cross-belt drilling, and large-angle drilling within a 360° horizontal plane. Adopting a modular structure and equipped with a fully hydraulic control system, it is simple to operate, structurally robust, and reliable, ensuring efficient and continuous drilling and rotation operations. With multiple functional linkages and independent adjustment of rotation and feed parameters, it enables fast drilling, drill pipe handling, and tripping operations. Additionally, it includes various safety protections such as overpressure protection, electrical protection, and hydraulic self-locking to ensure construction safety.
