| Abstract: | On the basis of the synthetical analysis of the geological data and the field investigation of a super large collapse in 5 # water diversion tunnel of a mine,and through the analysis of the hole enlarging theory related to high pressure split grouting,a general plan suitable for controlling this collapse was selected and its detailed design was made and implemented.After the construction,a binded rock mass with the grouted vein as its skeleton was formed from the collapsed mud rock flow like loopse layer and the tunnel became self stabilized without any support.This method has of popularized value for those similiar mine areas. |
