Abstract: In order to study the deformation and failure of soft rock roadway excavation near fault aging characteristics and determine the reasonable support mode, a ventilation roadway in Anli Coal Mine as the background, the displacement of surrounding rock mass in the process of the excavation and the changing regularity of plastic zone are analyzed with numerical simulation considering the creep property of mudstone, and the “anchor + bolt + shotcrete+ grouting” combination supporting scheme is proposed. The results show that: when the supporting structure of roadway in soft rock near the fault is relatively weak, along the excavation direction, the radial displacement of rock mass on the roadway surface presents a single peak distribution, and its maximum value occurs about 3 m to 6 m from the fault fractured zone; when the roadway passes through the fractured zone and enters the mudstone section, the radial displacement of the cross-sectional rock mass will be linearly related to the excavation distance of the roadway; when the combined support scheme of “anchor + bolt + shotcrete + grouting” is adopted, the maximum displacement of the roof, floor and side wall will be reduced by nearly 84.9%, 83.8% and 89.2%, respectively, compared with that of the support scheme of “anchor bolt + metal net”.
