ZDY750 tunnel drilling rig parameters

Tunnel Drilling Rig Parameters Hydraulic Tunnel Drilling Rig Introduction
Tunnel drilling rig is a coal mine gas drainage drilling rig. Through in-depth on-site investigation and research, combined with the actual geological conditions of my country's coal mines, especially for coal mine underground tunnels with small cross-sections and gas levels A new type of drilling rig developed by Gao Er has been greatly improved in terms of practicality, reliability, drilling capacity, drilling efficiency and safety of use.
The tunnel drilling rig mainly consists of pump station\power head frame, column frame, console and drilling tools.
Application Scope of Hydraulic Tunnel Drilling Rig
Tunnel drilling rigs are mainly used for drilling gas extraction (discharge) and discharge holes, grouting fire extinguishing holes, coal seam water injection holes, anti-outburst pressure relief holes, geological exploration holes and other engineering holes in coal mines. Suitable for various coal seam rock formations with rock solidity coefficients.
