摘要：
The authors discuss issues of stage-wise rock bolting of mine workings. Using equivalent material models, permissible roof rock lamination for roof bolting in conformity with the excavation support standards is evaluated. The critical displacements of roof rocks that make stage-wise roof bolting impossible are calculated.
