Sealing Behavior and Flow Mechanism of Expandable Material Slurry with High Water Content for Sealing Gas Drainage Boreholes
Predrainage of coalbed gas by underground drilling is one of the main approaches for eliminating gas disasters in coal mines. Owing to the unsatisfactory sealing effect of conventional sealing materials, coalbed gas drainage boreholes face serious air leakage, resulting in a relatively low concentra...
