Fully hydraulic tunnel drilling rig for coal mines (for soft coal seams)
Fully hydraulic tunnel drilling rigs for soft coal seams Split tunnel drilling rigs Tunnel drilling rigs for Guizhou coal mines Water exploration drilling rigs
Suitable for rock solidity coefficient The soft coal seam, roadway or drilling surface is larger and higher than the gas drainage (discharge) hole drilled in the soft coal seam underground in the coal mine. It is an ideal equipment for pumping (discharging) gas from soft coal seams while drilling underground in coal mines, and solves problems such as abnormal drilling and low hole formation rate caused by hole collapse, stuck drill, and drill pinch.
Main technical features
Fully hydraulic combined drilling rig with power head and split structure, convenient for underground transportation, shifting and installation.
The drilling rig is composed of a hydraulic pump station, power head, frame, control panel, column support and other components. It is connected with high-pressure oil pipes during operation and is operated away from the orifice for safety.
The design of the hydraulic system is mature, simple, reliable, easy to master, and easy to analyze and solve when a fault occurs.
, double column or four column support, multiple holes can be drilled in one anchorage, light weight, high efficiency and strong applicability.
