  In this review, we discuss effects of quantum gravity on black hole physics.
After a brief review of the origin of the minimal observable length from
various quantum gravity theories, we present the tunneling method. To
incorporate quantum gravity effects, we modify the Klein-Gordon equation and
Dirac equation by the modified fundamental commutation relations. Then we use
the modified equations to discuss the tunneling radiation of scalar particles
and fermions. The corrected Hawking temperatures are related to the quantum
numbers of the emitted particles. Quantum gravity corrections slow down the
increase of the temperatures. The remnants are observed as
$M_{\hbox{Res}}\gtrsim \frac{M_p}{\sqrt{\beta_0}}$. The mass is quantized by
the modified Wheeler-DeWitt equation and is proportional to $n$ in quantum
gravity regime. The thermodynamical property of the black hole is studied by
the influence of quantum gravity effects.
