Triple Porosity Model and Its Application for Coal Seam Gas Injection Displacement of CH4

Energy Science &Engineering, EarlyView.
(1)Compared with injecting CO2, injecting N2 has a shorter penetration time, but the CH4 flow rate takes longer to stabilize, meaning the displacement process lasts longer. (2)The flow rate of CH4 rapidly decreases and gradually approaches 0; the flow rates of N2 and CO2 are 0 before breakthrough, then increase rapidly and eventually stabilize.

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.
