Abstract:In order to improve the evaluation accuracy of the mine strata pressure bumping danger,a related study was conducted based on the inversion technology of the 3D ground stress field.Taking No.Ⅰpanel of Guojiahe Mine as a study object,based on the analysis on the geological tectonic features,coal and rock physical mechanics test and the mine ground stress measurement,according to the multiple linear regression principle,a numerical simulation inversion was conducted on the 3D ground stress field. The ground stress of the 3D ground stress field within the study region was obtained.Under the comprehensive consideration on the tectonic stress and mining stress influences, a macro evaluation on the mine strata pressure bumping danger from No.Ⅰ panel and the accurate evaluation on the mine strata pressure bumping danger in a local section was realized. There were 11 strong mine strata pressure bumping dangerous zones and 5 medium mine strata pressure bumping dangerous zones divided.
