Characteristics of tunnel drilling rig: The drilling rig adopts mechanical transmission, has a simple structure, small volume, light weight, easy operation, and reliable performance. The drilling rig is equipped with a hydraulic chuck and a hydraulic feed cylinder.
This type of drilling rig adopts a fully hydraulic structure, consisting of three parts: the main engine, pump station, and control panel. The main engine is a split structure that can be further disassembled for easy handling; Mainly using hard alloy and diamond composite drill bits for rotary drilling, it can also be equipped with large-diameter spiral drill rods and coring drill bits to meet different drilling requirements. This drilling rig is a power head type base structure fully hydraulic drilling rig, mainly used for drilling gas drainage holes, anti outburst holes, grouting and fire extinguishing holes, coal seam water injection holes, geological exploration holes and other engineering holes underground in coal mines.
