The present step brings forward a series of calculation methods for the parameters of the anchored support, their number being therefore the expression of the difficulty when describing the phenomena which occur during the interactive cooperation between the anchors and the surrounding rock. The methods used the most by European mining are the analytical methods (the Bieniawski method, the self-supporting beam method and the method of the interaction between the massive rock пїЅ anchor пїЅ time) and the numerical ...

The result of the experimental and analytical researches for the appointment of underground excavations, considering the interdependence with the type of rocks met, the working conditions and the safety of the supports have highlighted that the rational use of the actual types of supports, the improvement of the constructive parameters and the design of new types, as a unitary system, needs to be justified taking into account the study of the mechanism of the interaction. The analyses carried out for the rock cond...
