    Stanowiskowe badania elementów obudów górniczych przy ich dynamicznym obciążeniu
    (2007) Pacześniowski, Krzysztof; Pytlik, Andrzej; Radwańska, Ewa
    This paper presents results of stand tests of elements of mine supports with increased resistance to dynamic loads. The increased resistance of the mine supports subjected to the tests is a result of improved work on the hitherto designs of supports. The application of the increased supports results in increasing safety on longwalls and mine roads in the areas with ground tremor hazard. This paper shows dynamic characteristics of reaction of the mine support elements the resistance of which to dynamic loads has been improved as compared to the hitherto constructive solutions. Also the stand used for testing elements of mine supports under dynamic loads is described. The technical possibilities of the stand as well as the measurement and recording instruments used during the test are presented.
