    • Abstract
  • In order to solve the support problem in deep soft rock roadway, we research deformation law of surrounding rock and analyze of interaction mechanism of extra-long bolting and surrounding rock in crossheading of 11030 working face, the typical deep soft rock roadway of Zhaogu No.2 Mine. It indicates that the combined support technology of extra-long bolting and bolting is more adaptable to continual deformation of surrounding rock. The industrial experiment in Zhaogu No.2 Mine shows that, by using the support technology of long anchor bolt and anchor bolt, the biggest roof subsidence reduces by 34.6% and the surrounding rock continual deformation in later stage is controlled efficiently. The surrounding rock becomes stable in short time.
