  If large extra dimensions exist, the Planck scale may be as low as a TeV and
microscopic black holes may be produced in high-energy particle collisions at
this energy scale. We simulate microscopic black hole formation at the Large
Hadron Collider and compare the simulation results with recent experimental
data by the Compact Muon Solenoid collaboration. The absence of observed black
hole events in the experimental data allows us to set lower bounds on the
Planck scale and various parameters related to microscopic black hole formation
for a number ($3-6$) of extra dimensions. Our analysis sets lower bounds on the
fundamental Planck scale ranging from 0.6 TeV to 4.8 TeV for black holes fully
decaying into Standard Model particles and 0.3 TeV to 2.8 TeV for black holes
settling down to a remnant, depending on the minimum allowed black hole mass at
formation. Formation of black holes with mass less than 5.2 TeV to 6.5 TeV (SM
decay) and 2.2 TeV to 3.4 TeV (remnant) is excluded at 95\% C.L. Our analysis
shows consistency with and difference from the CMS results.
