Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review
Safety Science and Technology, EarlyView.This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
