    Obliczanie osiadania powierzchni terenu przy eksploatacji złóż ropy i gazu
    (2009) Sroka, Anton; Tajduś, Krzysztof
    Underground exploitation lead to decrease a fluid pressure inside porous rock mass and to the disturbances of initial state of stress inside a strata. Consequently, it cause a deformation of porous deposit which can be describe by Biot's theory. It's produce a movements of overburden rock mass reaching to the surface. Article presents the method which allow to determinate the subsidence for every point on the surface based on classical theory of geomechanics and Knothe's theory. It allow to take into consideration a three-dimensional geometry of fluid deposit, properties of rock mass and value of pore-pressure. In article, authors presents a model prognosis of surface subsidence received for a one deposit in Western Europe.
