Abstract: This paper presents a case history of the mined area treatment of a coal mine.  The design grouting scheme for the treatment was selected based on the specific conditions of the mined area and the site subsurface conditions. Details of the grouting design and the measures for dealing with the adverse conditions during the grouting process are also introduced. The test boring, water pumping and crosshole CT scanning techniques were used to verified the grouting results. The testing results indicated that the goals were achieved.

Key words: Mined-Area, Grouting Method, Grouting Verifications
