For hydraulic projects with deep gob area beneath the ground , the foundation treatment is always difficult . This paper presents the grouting techniques to fill the gob area practically adopted in large scale hydraulic projects in Yuzhou mining area , including the selection of grouting materials , the drilling arrangement and distance of grouting holes, the grouting pressure, the blocking method, and the grouting scheme, etc.Practical examples show the effective-ness of the presented techniques .
