    Abstract:
    In this work the model is constructed to describe the black hole
    enclosed in the dust cosmological background in case of zero spatial
    curvature. This model is based on our exact solution of the class of LTB
    inhomogeneous solutions. We considered the properties of the model and
    built the R-T-structure of the resulting space-time. It was shown that
    central region includes the Schwarzchild-like black hole. We derived the
    equations of motion of the test particle from the point of view of the
    observer comoving with cosmological expansion. We found analytical
    expressions for observable orbital and radial velocities of the particle
    and plotted the surface profile of the total velocity in this case. In
    comoving coordinate frame it is impossible to study the questions
    concerning the black hole horizon but one can observe the local motion
    of the particles influenced by the cosmological expansion.
