Abstract: Silty orebody is a typical kind of scattered medium,where the excavation and maintenance of tunnel is very difficult.That grasping the deformation laws of the tunnel surrounding rock is the precondition for searching reasonable constructing principle and supporting scheme. The middle section of tunnel in Jinshandian Iron Mine and surrounding rocks (with the silty orebody referred to,only) are taken as research object, comprehensive tunnel monitoring has been designed for the reseach purpose,the observation over comparatively long period has been conducted on the condition of the force-exerted and deformation on the tunnel and the surrounding rocks. The laws of deformation characteristic of the silty orebody as tunnel surrounding rock are obtained analytically.

Key words: silty orebody, scattered surrounding rock, mine tunnel, laws of deformation
