Tunnel drilling rigs refer to fully hydraulic tunnel drilling rigs for coal mines. Full hydraulic tunnel drilling rigs for coal mines mainly use carbide and diamond compact bits for rotary drilling. Hydraulic tunnel drilling rigs are widely used for water exploration, water injection, and gas exploration at different angles in mines. Drilling holes, geological exploration, slope anchoring and other drilling construction.Tunnel drilling rig specifications:ZLJ-250, ZLJ-350, ZLJ-400, ZLJ-700.
Specification
Product structure of tunnel drilling rig:This type of tunnel drilling rig adopts a full hydraulic structure and is divided into three parts: the main engine, the pump station, and the console. The main engine is a split structure, which can be further disassembled and easy to handle; it mainly uses cemented carbide and diamond composite drill bits for rotary drilling, and can also be used for rotary drilling. Equipped with large-diameter auger rods and coring bits to meet different drilling requirements Slurry fire extinguishing holes, coal seam water injection holes, geological exploration holes and other engineering holes.
