Abstract: The mathematical model of fluctuation of a console beam is considered at its partial roof fall and results of calculation of own frequencies of fluctuations, the periods of fading fluctuations and attenuation factors are resulted at various lengths of the console after its destruction. Possibility of use of the computer program for the characteristic of behavior of soils of the basic roof and an estimation additional weight on a coal layer is shown from overlying soils.

Key words: fluctuations of the basic roof frequency a console beam attenuation factor mathematical model additional weight parameters of support
