| Abstract: | In this paper,the surrounding rock of the NO.5 working face of no.16 coal seam in the South No.2 Lower mining area of Dongrong No.2 Mine was taken as the research object.Rock mechanics tests were carried out on different loading methods to analyze the mechanical properties and energy evolution law of rock during the loading process.It provides basic data for the study of roadway surrounding rock energy distribution,deformation and failure mechanism and roadway surrounding rock stability control. |
