The article proposes a base-line design of the system in the form of lattice girders to support peripheral rock masses of workings. The design scheme and its parameters of support and loading conditions are given, the simulation results are shown. Designing a ‘reinforcing’ support system suitable to be installed into the channel slots formed in the surrounding rock mass and developing a process to construct this support are the prime considerations in tunnels driven using the new mining technology. Helix and longitudinal channel slots excavated by the geokhod in the border zone during tunnel excavation should be used to provide a potential for increasing bearing capacities.
