    Changes in coal permeability in the process of deformation

  • Original language description

    The method of gas permeability measurement in triaxial state of stress by means of triaxial cell KTK100 was developed in the Institute of Geonics AS CR. A series of measurements was undertaken to find the parameters influencing gas permeability. The changes in permeability of coal samples during deformation process were determined even after the postfailure part. The samples were tested either at increasing confining pressures (5 to 50 MPa) or with a constant confining pressure and increasing axial stress.

    Změny propustnosti uhlí v procesu deformace

  • Czech description

    Na Ústavu geoniky AV ČR byla vyvinuta metoda měření plynopropustnosti v trojosém stavu napjatosti v triaxiální buňce KTK 100. Byla provedena série měření s cílem zjistit parametry ovlivňující propustnost. Vzorky byly testovány buď za zvyšujícího se bočního tlaku (5-50MPa) nebo konstantního bočního tlaku a se zvyšováním osového tlaku. Změny propustnosti v průběhu zatěžování byly měřeny i za mezí pevnosti.
