Sep 25, 2012 · Most importantly, four design acceptability criteria, i.e. load, displacement, energy, and system compatibility criteria, must be satisfied by any design. By following these design acceptability criteria, a clear distinction between the rockburst support design and conventional rock support design …Cited by: 215

For the linguistics formalism, see Q-systems. For the genetic method, see Q-system (genetics).. The Q-system for rock mass classification is developed by Barton, Lien, and Lunde. It expresses the quality of the rock mass in the so-called Q-value, on which are based design and support recommendations for underground excavations.. The Q-value is determined with

1. An overview of rock support design 1.1 Introduction The potential for instability in the rock surrounding underground mine openings is an ever-present threat to both the safety of men and equipment in the mine. In addition, because of dilution of the ore due to rock falls, the profitability of the mining operation may be reduced

Sep 25, 2012 · The design of rock support in burst-prone grounds differs from conventional rock support where controlling gravity-induced rockfalls and managing shallow zones of loose rock are the main target. Rock support in burst-prone ground needs to resist dynamic loads and large deformations due to rock dilation, called bulking, during the violent failure of rock.Cited by: 217

Design methodology Rock support refers in general to any measure aiming to stabilise rock masses by using support elements. Support elements may be rockbolts, cables, meshes, straps, lacing, shotcrete (i.e. sprayed concrete), thin liners, steel sets, shotcrete arches and cast concrete lining.Cited by: 12

The Q-system can therefore be used as a guideline in rock support design decisions and for documentation of rock mass quality. The Q-system was developed at NGI between 1971 and `74 (Barton et al. 1974).

Rock support is the term widely used to describe the procedures and materials used to improve the stability and maintain the load bearing capacity of rock near to the boundaries of an underground excavation. In this paper, a distinction is drawn between rock reinforcement or active support, where the supporting elements are an

Furthermore, rock bolting can be satisfactorily used to meet a variety of geological conditions and various support requirements. Roof bolts are available in many forms and the methods to attach them to the rock mass are almost as varied.
