The problem of dynamic failure of salt interchamber pillar is considered. Through theoretic investigations made, the possibility of the said above phenomena at momentary ceiling caving in conditions of multi-bed mining is shown. According to the results of physical modeling, dynamic effects in pillars may occur during the caving of the ceiling having a considerable thickness. As for Upper Kama Deposit, the elastic features of salt rocks of upping strata, by which the danger of dynamic failure of pillars may be conditioned, are defined.
