Mining Borehole Grouting Packer

• Expandable rubber sealing section conforms to the borehole wall.

• Central passage for grout or sealing material injection.

• Suitable for coal mine gas drainage boreholes and underground grouting work.

• Multiple models available for different borehole diameters.

The Bangtian mining borehole grouting packer is an expandable sealing tool used for post-drilling grouting and borehole sealing underground. After expansion, the reinforced rubber sealing section presses against the borehole wall to create temporary isolation. The central passage allows grout or sealing material to be injected into cracks, coal seams or surrounding rock for sealing, reinforcement and leakage control.

• Post-sealing and air-leakage control for gas drainage boreholes.

• Reinforcement of fractured coal seams and fissured rock.

• Roadway surrounding-rock reinforcement and water shutoff.

• Chemical grout injection where targeted borehole sealing is required.
