In this article, we introduce a new effective model for the Kantowski-Sachsspacetime in the context of loop quantum gravity, and we use it to evaluatedepartures from general relativity in the case of Schwarzschild black holeinterior. The model is based on an effective Hamiltonian constructed via theregularized Thiemann identities in the $\bar \mu$-scheme. We show that, incontrast with the $\mu_o$-scheme studied in [1], the classical limit imposescertain alterations of Thiemann identities as well as restrictions on thechoice of regulators. Once we define the Hamiltonian, we derive the equationsof motion for the relevant variables and proceed with the solving usingnumerical methods, focusing on a specific choice of $\bar \mu$. We establishthat for a Schwarzschild black hole interior, the effective dynamics leads to aresolution of the classical singularity and the emergence of an anti-trappedregion bounded by a second Killing horizon. We then perform a comparison of thedynamical trajectories and their properties obtained in the new model and somemodels present in the literature. We finally conclude with few comments onother choices of the regulators and their consequences.
