Abstract (in english)
   The acquaintance with parameters of disjunctive structures in the shaft pillar is an indispensable consition for controlling the expected deformation of the rock mass. Some geometric elements of the studies discontinuityy planes, such as strikes (directions), sense amd angles of slope and, above all, frequency values have been defined. In fault structures, the relative displacement has been mentioned. The results have been processed both in rosette diagrams and tabularly. Disjunctive structures are considered as important geological factors, which together with other (e.g. mechanical) ones, occuring during the mining operations, adversely affect the original equilibrium within the rock mass and are a frequent cause of rock pressure phenomena (detonations and rock bursts) in burst-phone areas, where this mine belongs. According to the own classification of the Kladno-2 mine, 1768 rock bursts of various intensities have been recorded within the shaft pillar during the year 1993
