Determination of bulk rock pressure on the support structure
Authors:
Abstract
Bulk rock is characterized by the following: 1) loose rock massif consists of separate, not connected with each other pieces of hard rock; 2) pieces of rock are small enough in comparison with the width of excavation, which practically excludes the possibility of vaulting; 3) the shape of pieces and their location determine the possibility of lateral spreading forces by mutual wedging under the action of load. Often it is necessary to support excavations under the collapsed rock or stockpile, the properties of which are often close to loose rock.
