Abstract： In the process of traditional coal mine water prevention and control, ground drilling method was adopted to identify overlying aquifer water conduction fracture zone height of mining and excavation working face, which had low precision and poor efficiency. For accurately calculating overlying aquifer water conduction fracture zone height, Simingshan mine decided to adopt water injection observation method to observe No.9103 working face overlying water conduction fracture zone. According to the practical application, No.9103 working face overlying rock water conduction fracture zone height was measured accurately by the method, which achieved good results.
