Back Analysis of 3-D Initial Geostress of Laohutai Coal Mine by the Method of Multiple Regression and FLAC^3D

Abstract:

Initial geostress is one of the most important factors in coal mining. By combination the finite difference software FLAC^3D with multivariate linear regression theory, 3-D initial geostress in situ is back analyzed, which also considers the effect of gravimetrical and tectonic stress. The back analysis results of initial geostress in Laohutai coal mine are in a good agreement with the in-situ test results, which provides theoretical support on prediction of geostress and also more convenient geostress data in coal mining.
