In order to master the stress distribution and overburden movement law during the mining operation of the No. 2 coal seam in Xinzhi Coal Mine, the distribution law of overburden zones and advanced bearing pressures in the working face were specifically analyzed. The overburden zones were distributed using theory, simulation and actual measurement. The pressure distribution of the advanced support was specifically analyzed using on-site measured analysis methods. The results showed that the development heights of the overburden collapse zone and fracture zone in the large mining depth working face were in the range of 17 ~ 25 m and 30 ~ 35 m respectively; the range of advanced bearing pressure in the working face was 50 m.
