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.

The wear of materials in hydraulic transport pipelines [PDF]
, 1988 Bibliography: leaves 60-68.The hydraulic transportation of particulate solids through pipelines results in wear of the pipeline walls. The lifetime of the pipeline is determined by this rate of material loss and is therefore critical to the designer. Due
