Experiment for deformation failure in roadway coal-rock tunnel with half oblique wall-arched

In order to study the strata behaviors characteristics of mining disturbance in the coal-rock tunnel due to the complex conditions of the mine tunnel and mine environment,analyze experiment of deformation failure characters by the method of combining physical modeling and numerical simulation similar in roadway coal-rock tunnel with half oblique wall-arched.With two-phase difference confining pressures mode to load tunnel model boundary in the experimental design.The results show,test data coincided with the field,so design programs can better simulate field.Roadway local stress completely release,lead to floor heave and right sides deformation failure and mainly along the seam and the direction of the tendency of weak rock.The results provide references for roadway support and similar similarity simulation.
