摘要
Abstract
To solve the problems of severe deformation and damage in the fault fracture zone along the 6300 track crossheading of Xinglongzhuang Coal Mine,as well as the failure of the"anchor rod cable+metal mesh"combined support technology,based on the results of on-site drilling and peeking and the mechanism of surrounding rock damage,a layered grouting reinforcement technology scheme of"shallow part grouting pipe+deep part grouting anchor cable"is proposed.The on-site practice results show that the displacement convergence of the roof,floor,and two sides of the roadway is stable at 68 mm and 47 mm,and the layer separation amount of deep and shallow are controlled within 23 mm and 7 mm,respectively.The deformation of the surrounding rock is effectively controlled.关键词
