  We discuss a field theoretical framework to describe the interactions of
non-thermal quantum black holes (QBHs) with particles of the Standard Model. We
propose a non-local Lagrangian to describe the production of these QBHs which
is designed to reproduce the geometrical cross section for black hole
production. This model is implemented into CalcHEP package and is publicly
available at the High Energy Model Database (HEPMDB) for simulation of QBH
events at the LHC and future colliders. We present the first phenomenological
application of the QBH@HEPMDB model with spin-0 neutral QBH giving rise the
$e^+e^-$ and $e\mu$ signatures at the LHC@8TeV and LHC@13TeV and produce the
respective projections for the LHC in terms of limits on the reduced Planck
mass and the number of the extra-dimensions.
