Product Description
The Hydraulic Roof-Cutting Waterjet System is a high-pressure abrasive waterjet device designed for underground roof cutting and roof drilling in coal mines. Using cold-cutting technology to replace conventional blasting, it delivers safe, efficient, and precise cutting performance. The system operates reliably in confined or complex roadways and is widely applicable to gob-side entry retaining, roof pre-splitting, and roadway control engineering.
High-Pressure Cold Cutting
Uses abrasive waterjet directional cutting with no heat, sparks, or explosive hazards, preserving the in-situ geological structure.
High Efficiency
Reduces roadway construction cost per meter by nearly 50%, delivering significant economic benefits.
Dual Cutting
Suitable for both roof cutting and roof drilling, meeting multiple underground engineering needs.
Long Continuous Operation
Large abrasive tank capacity enables up to 40 minutes of continuous operation.
Excellent Mobility
A crawler chassis with ±16° climbing capability ensures reliable movement in uneven mine environments.
