Modeling interaction of suspended monorail rock bolt support and rock mass

In view of crossover intensification in mining, activity of auxiliary transportation also grows, and an appreciable percentage in this respect belongs to the suspended monorail transport in modern mines. Suspended monorail systems widely use rock bolt support, in complex geological conditions of underground mining in Kuzbass equally. In the meanwhile, geomechanical validation of engineering solutions on rock bolt design for the suspended monorail transportation yet remains deficient. For this reason, investigation of geomechanical processes caused in coal-and-rock mass by interaction between monorail rolling stock and rock bolting is of relevance and practical significance. This article describes the design model of interaction between the suspended monorail rock bolt support and rock mass at different load levels. A case-study of the Yalevsky Mine of SUEK-Kuzbass presents the mathematical modeling of the stress–strain behavior of the rock bolt–rock mass system. The modeling results prove estimability of rock bolt support stability under the action of load from the suspended monorail transport.

Keywords: underground opening, rock mass, suspended monorail, rock bolt support, stresses, strains, stability.
