Disturbance Effects by Excavation of Neighboring Roadways in Deep Coal Mine
Numerical simulation method and on-site dynamic monitoring are used to study a railway laneway disturbed by excavation of neighboring roadways under high in-situ stress in a deep coal mine of Huainan region. The paper presents a series of variation trend about stress state, deformation, plastic zone and tension of cables under disturbance effects based on the simulation results, and the evolution of surface displacement of railway laneway is also discussed according to on-site monitoring data. The analysis shows that disturbance effects have spatiotemporal characteristics and support structure should be installed in a short time which helps to reduce disturbance by construction of adjacent caverns.
