THE MODELING OF THE INTERACTION OF ROCK MASS AND COMPLIANT LINING WHILE IT IS EXPANDED

English abstract

The bearing capacity of metal lining from a special interchangeable profile was studied under the conditions of its interaction with the rock mass both in expanding and in compliant modes. The purpose of research is the development of methods for managing the state of mine working by adapting its parameters to the rock pressure effects. The idea of the work is to numerically model the interaction of the rock mass and arched compliant lining during its expanding. In this case, the lining was imitated using a rod system of finite elements. As a result of the studies, the parame-ters of the lining are determined, which ensure the reliable functioning of the mine working throughout its entire service life. In order for the lining to work efficiently, the filling of voids beyond it is needed. In this case, however, the compliant ele-ments must have the strength of resistance that higher than that of existing lining structures. The results of studies can be used in the construction of tunnel-like mine workings.
