Paper Title:
Back Analysis of 3-D Initial Geostress of Laohutai Coal Mine by the Method of Multiple Regression and FLAC3D
  Abstract

Initial geostress is one of the most important factors in coal mining. By combination the finite difference software FLAC3D 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.
