The fully hydraulic tunnel drilling rig for mining is mainly used for drilling gas drainage holes, grouting fire extinguishing holes, coal seam water injection holes, anti outburst and pressure relief holes, geological exploration holes, and other engineering holes underground in coal mines. Specially suitable for horizontal drilling of ± 30 ° underground in coal mines and allowing for all-round applicability of ± 90 °.
The significance of the model of fully hydraulic tunnel drilling rig for mining
Model example: Type coal mine hydraulic tunnel drilling rig:
Z represents the drilling rig;
D represents the power head type;
Y represents hydraulic drive;
Main technical characteristics of fully hydraulic mining tunnel drilling rig
1. The power head fully hydraulic combination drilling rig has a split structure, which is convenient for underground transportation, displacement, and installation.
2. The drilling rig is composed of hydraulic pump station, power head, frame, control console, column support and other components. It is connected by high-pressure oil pipes during operation and operated away from the borehole for safety.
3. The hydraulic system design is mature, simple, reliable, and easy to master, making it easy to analyze and solve faults when they occur.
4. Double column or four column support, one-time anchoring can drill multiple holes, light weight, high efficiency, and strong applicability.
