Zusammenfassung: | The authors describe mathematical model to estimate stability of an extended pit wall. Dilatancy and internal friction angle are included. Based on a rigid–plastic model, maximum permissible height of pit wall from the viewpoint of its safety is estimated. The article gives relations of the maximum permissible pit wall height, pit wall slope and rock mass properties. |
