Abstract: This paper researched the height of "three zones" of the overlying strata of 2301 working face with large mining height
of Sanyuan Zhongneng Coal Industry Co., Ltd. of Changzhi of Jinneng Holding Coal Industry Group by adopting a comprehensive
analysis method, that is, theoretical calculation, simulation analysis and field measurement, and obtained the height of "three
zones" of the overlying strata of 2301 working face with large mining height. The heights of the collapse zone, fracture zone and
curved subsidence zone are 14.5 m, 14.5-51.4 m and 51.4 m or more respectively.

Key words: large mining height; "three zones"; numerical simulation; similar simulation; field measurement
