In this paper the author presents a survey of current understanding of the interrelationships among the hydraulic, mechanical, seismic and geometrical properties of single natural factures. The paper also includes a discussion of the methods that have been developed to improve the measurement of fracture geometry including the measurement of fracture specific stiffness, which is the key link in interrelating the physical properties of a fracture. A new approach for determining fracture shear sti...

Monitoring of the nature and amount of mining-induced stresses over pillars was undertaken at different coal seams with shallow depth cover and varying overlying strata and goaf treatment. The development of abutment loading on the coal pillars facing goaf line is visualised by analysis of the in situ observations at different sites with varying geomining conditions. The rock properties and depositional conditions of the immediate roof strata at each site were studied and incorporated in terms o...

Abstract A non-linear failure envelope of hyperbolic type in terms of effective stresses for rock discontinuities is described by a simple three parameter expression, which contains the basic angle of friction, the roughness angle and the median angle pressure. The components of friction, dilation and breakage of asperities are derived. The proposed expressions are related to the widely used failure law of a logarithmic type proposed by Barton and the simple correspondence of two sets of paramet...

This review from the Commission on Rock Grouting seeks to provide a better basis for the optimal selection of grouting materials and methods to meet specific needs and conditions. It examines current worldwide experience of grouting under a variety of conditions and using all available techniques and materials. The review is presented under the following sections: rock properties; properties of the grouts; planning of grouting operations; installation at the construction site; review of the succ...

Beginning with the original work of Shi [Discontinuous deformation analysis: a new numerical method for the statics and dynamics of block systems. Ph.D. thesis, University of California, Berkeley (1988)], called the Discontinuous Deformation Analysis (DDA) method, a number of extensions to the method have been explored. The extensions consist of improving the contact algorithm, adding block fracturing and sub-blocking capabilities. Contacts between blocks have been modeled using an Augmented Lag...
