Abstract
According to the data of stress measurement,researched the stress distribution regularity of No.9 coal seam floor and 3D finite-element numerical simulation in Xian Dewang Coal Mine.It is provided that the data of No.9 coal seam floor's failure depth. The study results provide scientific basis for the safety in mining.
