Assuming that the roadway in the mining area is not affected by mining-induced disturbances, the surrounding rock of the roadway under the original in-situ stress, based on the principles of temporal-spatial effects and stress release expansion, exhibits a phenomenon where the loosening and deformation of the surrounding rock increases slowly over time. This phenomenon is referred to as the creep behavior of the surrounding rock in the roadway. Compared to mining-induced stress, the influence of geological stress primarily occurs at greater depths, and its impact is generally slower. Therefore, the displacement and deformation caused by geological stress can mainly be observed.

摘要

Assuming that the roadway in the mining area is not affected by mining-induced disturbances, the surrounding rock of the roadway under the original in-situ stress, based on the principles of temporal-spatial effects and stress release expansion, exhibits a phenomenon where the loosening and deformation of the surrounding rock increases slowly over time. This phenomenon is referred to as the creep behavior of the surrounding rock in the roadway. Compared to mining-induced stress, the influence of geological stress primarily occurs at greater depths, and its impact is generally slower. Therefore, the displacement and deformation caused by geological stress can mainly be observed.
