Abstract: Devloping scale of overlying strata roof water flowing fractured zone caused by thick coal seam full-mechanized mining technique effects water control safety evaluation results directly. Taken the Sihe Mine at Jincheng as an example, research was done on 3# coal roof water flowing fractured zone by using consumption of rinsing liquid method, drill hole colour television observation method and RFPA. The research results provide reference significance for mine of similar condition in mining area of Jincheng.

Key words: Water flowing fractured zone observation, Thick coal seam, Mining area of Jincheng
