Loss of Pit-wall Stability and Rock Failure around Mine Workings under Creep Conditions

摘要：

The present paper considers the long-term strength and creep of materials in terms of Couiomb-Mohr criterion. The calculated durability data are compared with test data. The limit states in creep conditions are studied for the plane strain.Failure time was evaluated for problems of the loss of pit wall stability under different load effects and rock failure around a circular, cylindrical mine working in creep conditions.
