  In this work we consider a recently formulated model of a black hole coupled
with radially directed flows of dark matter (RDM-star). In this model, a cutoff
by quantum gravity (QG) creates a core of Planck density, filled with a gas of
Planck mass particles, inside the star.
  Further, in this model, a fast radio burst (FRB) can be generated via the
following mechanism. An object of an asteroid mass falls onto an RDM-star. Due
to large gravitational forces available in the interior, the RDM-star works as
a powerful accelerator, boosting the nucleons composing the object to extremely
high energies. Upon collision with the core, the nucleons enter in deeply
inelastic reactions with the Planck particles composing the core. This process
is followed by stimulated emission of highly energetic photons. On the way
outside, these photons are subjected to a strong redshift factor, downscaling
their frequencies to the radio diapason, as a result producing an FRB.
  A straightforward computation gives a characteristic upper FRB frequency of
0.6GHz. With attenuation factors, it is stretched to a range 0.35-8GHz, fitting
well with the observable FRB frequencies. We also discuss the reconstruction of
other FRB parameters in frames of the model.
