Abstract

Based on the linear function between the maximum horizontal stress obtained by fitting the measured in-situ stress test result and buried depth, FLAC3D software was used in this paper to analyze the characteristics of lower-group roadway surrounding rock under the influence of multi-mining of deep nearly interval coal seam. The results showed that: There are relatively high stress concentration around roadway, especially on the left side and the roof, affected by space location during tunneling; The vertical stress and the maximum and minimum principal stresses of roadway surrounding rock are increasing, while the horizontal stress is decreasing during the mining of working face; During roadway excavation, Surrounding rock stress is asymmetry due to the asymmetry mining of near working faces and the multiple factors superposition affected by supporting pressure and original rock pressure, while both sides of the roadway are substantially symmetrical after the mining of working face.
