| Abstract: | To reveal the mechanism of large inhomogeneous roadway deformation under mining effects and realize effective control, this study employed multiple research methods to analyse the evolution laws of the stress environment and plastic zones of the 5105 roadway in service under the engineering background of the gob-side entry in Selian No. 1 Coal Mine, China. The mechanism of the large inhomogeneous deformation of the mining roadway was revealed, and a full-section differentiated control technique was proposed. Results demonstrate that the roadway at 5 m in front of the working face is under a stress environment, in which the principal stress ratio is 3.77 and the included angle between the maximum principal stress and the horizontal direction is 64°. This stress state induces inhomogeneous malignant extension in the plastic zone in the roof at the coal-rib side and in the floor at the coal-pillar side. A full-section differentiated control technique involving roof and rib reinforcement with asymmetric bolt/cable support and floor pressure relief by hole drilling and cable bolting was developed. Numerical simulation revealed the technique's good control effect. [ABSTRACT FROM AUTHOR] |
