Uranium deposits, between which gas storage are being designed, the Rožná depos it and Olší deposit, are situated on the east edge of the Strážek Moldanubicum in Bohe mian Masiff. Based on structural analysis it was possible to carry out the first rough prediction of potential weak zones in the rock mass. The structural analysis was also one of the supporting materials fo r determining the geometry and design method for the mine workings for the gas storage and for the advancing exploration o f the gas storage region. Until now, the measur ement of foliation planes and discontinuity planes in the survey crosscut V1-XXI and in a survey connecting gate GR1-XXI has been carried out. The results of interpretation of the measurement an d monitoring of ductile el ements (foliations) and joints (rupt ures) as well as dislocations in terpretation from the mine maps can be summarized and quoted in the contribution.
