Study On The Ground Stress Field Prediction And Roadway Control Based On Inverse Theory

Field measurement can provide the most accurate data on rock stress, but thereality conditions limits its widely use. Therefore, rock stress inversion of mine hasalways been an important part of the engineering and academic research.This paper was written based on a lot of reference reading both at home andabroad. This paper obtains the relationship between boundary conditions and stressdistribution, boundary conditions according to field measurements data and inversedthe rock stress field distribution of the Gucheng mine N1303first mining face areausing neural network structure and orthogonal experiment method to constructlearning samples combined with FLAC3D, matlab calculation software.based onGucheng Mining engineering example. This paper simulates the effect of how stressenvironment impact the roadway.and optimizes roadway supporting parameters underthe stress environment predicted.by inversion. Research of this paper has somepractical value in projects which have similar conditions.and certain significance inthe selection fo support parameters.
