FKSW Grouting-type Sealing Device for Coalbed Methane Extraction

FKSW Grouting-type Sealing Device for Coalbed Methane Extraction

Grouting-type (pressurized) sealing devices for gas drainage are used for gas extraction and hole sealing. By leveraging the grouting pump’s pressure, the device first fills the two end bladders with grout; as the bladders expand, the grout then seals the central gap, thereby achieving multi‑layer pressurized sealing. Gas is subsequently extracted through the drainage pipeline.
