ON MODELLING OF GEOMECHANICAL BEHAVIOR OF SUPPORTED ROCK MASS IN THE VICINITY OF UNDERGROUND STRUCTURES

The paper presents a method of modelling the mechanical behavior supported rock mass, in vicinity complex underground structures. is based on calculations effective properties bolted mass. algorithm unit that are obtained by conducting series numerical experiments. These experiments allow to define values correction factors, which, turn, determine difference and non-supported Such approach makes it possible calculate stress-strain state space structures precisely without direct considering roof bolting elements. application proposed demonstrated example an applied problem strength assessment geotechnical system “underground equipment chamber — enclosing potash mass”. results research have wide range applications since they can significantly simplify speed up process stability make more accurate.
