  We consider the classical Hamiltonian of the interior of the Schwarzschild
black hole in Ashtekar-Barbero connection formalism. Then, inspired by
generalized uncertainty principle models, we deform the classical canonical
algebra and derive the effective dynamics of the model under this modification.
We show that such a deformation leads to the resolution of the singularity of
the black hole and a minimum nonzero radius for the infalling 2-spheres,
provided that the deformation parameters are chosen to be negative.
