In order to improve the mine impact danger zone evaluation precision, relative study about 3D stress field inversion technology was carried out. No. 9 coal seam, No. 2 west mining area of Jixian Mine was taken as study object, based on geological structure characteristics analysis, coal rock physical and mechanical properties and mine ground stress measurement, according to 3D stress field numerical simulation inversion by multiple linear regression theory, relative information about 3D stress field inversion in the study field was obtained, in consideration of tectonic stress and the influence of mining stress conditions, No. 9 coal seam, No. 2 west mining area impacting danger macroscopic evaluation and precise evaluation of risk impact to local scope were realized, which guided the mine safety production.
