Abstract

The article describes preparation and implementation of experimental research into strength, deformation and acoustic characteristics of physical models of frame and honeycomb underground structures designed at the Research Center for Applied Geomechanics and Convergent Technologies in Mining at NUST MISIS College of Mining. An integrated test bench for physical and optical modeling of geophysical processes in the secondary stress fields, an installation and a special test bench for 3D physical modeling of any complexity are manufactured. The standard variants of physical modeling of the advanced frame and honeycomb underground structures are developed. The authors present the test data on strength, deformation and acoustic characteristics obtained on a model of a frame structure variant. The tests show that honeycomb underground structures exhibit higher stability when they contain more circular openings of smaller diameter.
