AB  - Height identification of water-permeable fractured zone (WPFZ) is one of the 
      decisive influence factors for mining safety, especially in some specific 
      conditions, such as mining under aquifer. In order to demonstrate the formation 
      process of the WPFZ, the scaling model experiment is carried out. Through the 
      analysis of movement and breaking in overlying strata, the WPFZ height is 
      significantly affected by mining range, movement characteristics of key strata 
      and its follow-up strata. Based on the research findings, a new theoretical 
      method, " overlying strata synchronous movement method " (OSSM) is established to 
      predict the WPFZ height. Taking 3301 mining face of Zhujiamao Coal Mine in China 
      as the engineering background, the WPFZ height is estimated by OSSM. 
      Additionally, the field detection is carried out by the downhole segmented water 
      injection method combined with borehole camera method. By comparing the results 
      of different methods, the accuracy of OSSM is verified and the WPFZ height is 
      determined finally. What s more, various methods for determining WPFZ height are 
      evaluated.
