Gas-containing coal seepage absorption and drainage mining simulation system

Gas-containing coal seepage absorption and drainage mining simulation system


This experimental system simulates the imbibition process of raw coal, briquette coal, and granular coal under axial pressure loading conditions, with external moisture injected in static/dynamic pressure modes; it monitors parameters such as axial pressure, water injection pressure, water injection volume, and gas pressure inside the coal sample tank in real-time during the experiment, and programmatically controls parameters like loading path, water injection pressure, and water injection volume according to experimental requirements. The equipment conducts research in the following areas: (1) Study of imbibition effects and differences in gas-containing coal with varying degrees of metamorphism/damage types; (2) Study of the impact of water injection pressure on the imbibition effect of gas-containing coal; (3) Study of the imbibition effect and mechanism of surfactant solution injection in gas-containing coal.
