Coal clast in the upper carboniferous sediments - environment, speed of transportation, alteration and history of diagenesis (Upper Silesian Coal Basin)
Martinec, Petr ; Kožušníková, Alena
Coal clast in upper carboniferous sediments in the Czech part of Upper Silesian Coal Basin - sedimentary environment, transport conditions, diagenesis and analysis of source areas.
Anomalous jointing of drill core in the Upper Silesian basin
Kožušníková, Alena ; Fialová, Věra ; Hoch, I.
Anomalous jointing of drill core observed sometimes in prospect holes in the Upper Silesian basin was analysed in the contribution.
Documenta geonica 2002. The 5th Czech and Polish conference Geology of the Upper Silesian Basin
Kožušníková, Alena
Presented papers of conference deal with wide problems - sedimentary evolution of the Upper Silesian Basin, new maps of the whole basin, correlation, dating, palynology and physical properties of rocks particularly coal.
Non-destructive methods of failure analysis of rock material in laboratory conditions
Kožušníková, Alena ; Konečný, Pavel ; Chmelová, J.
Presence of interconnected discontinuities such as cracks, fractures and joints significantly affects both elastic and transport properties of rock masses. Non-destructive methods of failure analysis of rock material are described in this paper.
Natural cokes in the exploration fields Frenštát - East and Čeladná - Krásná
Kožušníková, Alena ; Pěgřimočová, J.
In the exploration fields Frenštát - East and Čeladná - Krásná the layers of intrusions and natural cokes were found out. Chemical composition, physical properties and petrography of natural cokes are analysed. On the bore hole Č-1 the detailed analysis of layer of natural coke was carried out.
Influence of temperature on permeability and stress strain behaviour of granodiorite
Daněk, T. ; Konečný, Pavel ; Kožušníková, Alena ; Nowakowski, A.
Behaviour of rock samples in unaxial and triaxial stat of stress is influenced by a lot of factors as mineral composition and origin of the rock, degree of diagenesis etc. One of the important factors is temperature. Especially high temperature influences very strong the behaviour of the rocks. High temperature could be generated in varous ways in rock massif. The research results could be improved in solution of serious problematic of burning in tunnels, underground waste storage or modelling of temperature field in rock massif.
Documenta geonica 2001. Geonics 2001. Temperature and its influence on geomaterials
Konečný, Pavel ; Kožušníková, Alena
Institute of Geonics organized during the last decade the series of international conferences Geomechanics (1991-1993-1996).In the connection with recent research activities of the Institute of Geonics, the relevant questions of temperatures and their influence on geomaterials was picked up as the topic of the symposium Geonics 2001.
