because the natural stress field is changed due to tunneling roadway, a stress concentration area appears in rock of surrounding roadway that cause roadway deformation or destruction.
由于巷道掘进破坏了原巖地应力场,使围巖应力重新分布,应力集中区的高应力造成巷道变形破坏。
the results provide a basis for controlling additional roadway deformation efficiently and ensure the regular production of the mine.
