1. This equipment is suitable for hydraulic cavity formation processes during underground coal mine drilling, enhancing gas permeability to achieve gas extraction and coal seam pressure relief.

2. Once the water pressure reaches the opening pressure, the water jet cutter’s dual-wing blades are deployed, performing cavity formation in coordination with drill pipe rotation.

3. Key components undergo heat treatment processing, ensuring high hardness and strong wear resistance.

4. Sealing materials are made of high-performance synthetic rubber, providing excellent sealing properties and strong resistance to aging, high temperatures, and fatigue.
