Abstract：The evolution rule with the increasing pressure difference of rock pillars? damaged zone of different storage spaces is studied by geomechanical model test. The followings are completed mainly：(1) Firstly，several key techniques related to the experiment model test are studied，including model material，generation system of crustal stress，loading and unloading system of cavity pressure and measurement techniques. And a new method to generate trapezoidal-distribution stress with spherical particle is put forward. (2) Secondly，three experiment schemes are planed and accomplished. Last but not least，numerical simulation of the model test is carried out and the results are contrasted with that of the model test. The conclusion is that the stability of the rock pillar between pressurized caverns is the determinant factor for preventing the chain breaking of cavern group.
