Permeability measurement will be made at triaxial state of stress simulating rock massif conditions. The experiments will be realised at various confining pressure for three rock materials of different genesis (sandstone, granite and marble) and at various temperature. Important partial task is determination of mode of running hot - character of atmosphere, speed and time of heating. Rock material will be both before and after the heating investigated by a micropetrographic and microtectonic analysis by various methods - optical analysis, computer tomography, velocity of ultrasonic waves. These analysis will be specialized especially in creation of new discontinuities in consequence of increased temperature and in phase transformation of minerals at higher temperature."@en .
