Abstract

The authors propose the approach to validation of the surveying control accuracy in safety monitoring of earth dams in terms of liquid waste receivers at mines. Based on the system structuring of types of earth dams and their elements, estimation of influence of loads and effects exerted to these structures, as well as the analysis of accident The article presents the installation meant for the determination of gas permeability of rock specimens placed in a testing cell with the adjustable axial and lateral compression. The installation includes a measurement system for the automated long-term investigation of rock permeability in accordance with the preset program. It is also possible to test specimens with a fracture filled with a propping material. The reported data of the permeability tests of porous quartz-containing material and coal demonstrate the capacity of the installation and the experimentation specificity.
