Abstract
Those properties that directly affect the mechanical behavior of the rock mass and stability of the mining and drilling, they also affect the ability to call Geomechanical features. In this research, the stability of rock masses of Giladeh construction mine Astara city is investigated. For this three classification of rock masses RMR, Q and GSI method are used. The results showed that the stability of the rock mass is good and capable of drilling in rock mining based on the Weaver (1975) is difficult and very difficult. It is anticipated that the impact of earthquake ground shaking is only included on mine. Slip into local ground failure phenomena may also affect the scope of the stairs.
