ABSTRACT  Full text (pdf)

The computer program ADINA is used for the pressure analysis on the model of the underground opening,  trapezoidal in  shape in layers of lignite. An analysis was madebefore, during and after the setting of three and five anchors. The theory about pressure distribution for secondary and tertiary pressure condition in the roof and board sides of the opening by setting anchors has been proven. In order to check the result, test of pulling out anchors from the roof of the opening has been done. The examinations and research conducted at the level of obtained results show the efficiency of setting underground opening by using anchors where there are multilayered deposits of lignite. The results of the research provided in this paper can also be used for underground openingsin different shapes inmultilayered deposits.
 
Key words: pressure conditions, multilayered deposits, substructure, anchor, ADINA
