Underground Drilling Rig for Coal Mine

This drilling rig is applicable to the construction of gas drainage holes, water exploration and drainage holes, pressure relief holes and other engineering holes during underground drilling in coal mines. Featuring compact structure and adjustable drilling height, it adapts to working conditions such as multi-layer drilling, cross-belt drilling and large-angle drilling within a 360° horizontal range. It adopts modular structure and full hydraulic control system, featuring simple operation and stable and reliable structure, which ensures efficient and continuous drilling and rotary operation. It supports linkage of multiple functions and independent adjustment of rotary and feed parameters, enabling rapid drilling, rod reversing and tripping operations. Meanwhile, it is equipped with various safety protections including overpressure protection, electric protection and hydraulic self-locking to guarantee construction safety.
