| Abstract | We study singularities and Artin’s contraction theorem for orbifold surfaces. Our
main result has a consequence which is in the direction of the birational Minimal Model
Program for b-terminal orbifold surfaces. For example, we ascertain the nature of extremal
contractions for such $b$-terminal pairs.
