ZLJ-200 coal mine tunnel drilling rig is mainly used for water exploration, gas exploration and release, dust prevention and water injection at different angles underground in coal mines, as well as various engineering and geological structure holes. It is mainly used inside the mine for drilling 0-360 degree water exploration and release holes, geological structure holes, fire suppression holes, gas extraction and other engineering holes. It can also be used for drilling geological drilling holes and other engineering holes on the ground. Iron ore is used for drilling rocks to facilitate the mining of ore.
Product Features of ZLJ-200 Tunnel Drilling Rig for Coal Mines
ZYJ-200 tunnel drill for coal mines adopts mechanical transmission and hydraulic feeding. It has a simple structure, small size, light weight, easy operation, and reliable performance. The drill is equipped with a hydraulic chuck and a hydraulic feeding cylinder.
This machine is used for drilling and grouting in subway tunnels, cable trenches, and foundation pits. It is also used for ground geological exploration, building foundation reinforcement, and various water and coal exploration and drainage in coal mines, iron mines, and gold mines.
