The paper gives description of method of estimation of pit wall based on simulation of sliding surface. The calculation example is given.
This article respond the question about using the digital photographic data in open-cast mine for specification of structural easing factor and his application for modeling of stsbility in open-cast mines with «Phase2» and «NEDRA».
Account method of laser-scanning survey of hydraulic engineering tunnels of 2,7 km is stated in the general extent. The visual way of inspection of the tunnels, carried out in parallel with their leveling is resulted. The way of a deformation estimation of a condition of tunnels by the geometrical analysis of 3D-models received according to laser-scanning survey is considered.
