Failure cause and pressure behavior law of soft rock laneway in deep mine

Based on the measured results and field survey, the cause of the failure and deformation of the surrounding rock around soft rock laneway in MaLuPing mine are discussed. Through numerical simulation with FLAC^3D, the ranges of the fragmentation area and the plastic area, the distribution of stresses and strains of the surrounding rock around laneway are analyzed to put forward theoretical basis for the choice of reasonable support form.
