The root model (ADD, arXiv:hep-ph/9803315) of the only mechanism class under which LHC collisions could form black holes: with the true Planck scale at ~TeV, trans-Planckian parton collisions become possible at colliders. The framework abandons supersymmetric unification, trades the m_EW/M_Pl hierarchy for a mm-vs-weak-scale hierarchy (argued stable, a property of a solution rather than a fine-tuned Lagrangian parameter), and requires unknown TeV-scale quantum gravity to suppress dangerous proton-decay and flavor operators by assumption. Primordial nucleosynthesis survives (MeV energies excite no gravitons); an explicit 6D vortex construction with Pati-Salam bulk group is given as existence proof.
