Abstract:Appropriate supporting scheme of deep roadway surrounding rock is Sthe key technology of deep mining inSSthe modernSmines,which needs to solve. In Dashuigou mining area, the developing roadway in 2815 middle section, because of deep embedding, great geopressure, high in-situ stress and poor stability of wall rock. Due to the mechanical excavation interfere, the roadway surrounding rock stress redistribute, and the roof fall phenomenon become serious. In order to control the influence of the pressure of surrounding rock of roadway, ensure the safety of roadway drivage, mining area through field investigation and analysis, decide to use New Austrian Tunneling Method, and finally the roadway smoothly get through the soft rock broken zone. By studying the basic principle and application of the New Austrian Tunnelling Method,results were achieved that roadway drivage in broken weak rock mass, Suse New Austrian Tunnelling Method, low cost, high efficiency. With the increase of the deformation of surrounding rock, the release quantity of plastic energy increases,Sthe supporting thickness increases. In addition, with the passage of time, the deformation of surrounding rock of roadway no longer changes. Accurately grasp the deformation characteristics of surrounding rock, determine the reasonable support parameters and supporting time, can economically and effectively guarantee the stability of surrounding rock of roadway, which has very important engineering value.
