Paper presented at the 2nd North American Rock Mechanics Symposium, June 19–21, 1996
Paper Number: ARMA-96-1977
.... The weakest link in the mass constitute shale interbeddings. So, the mechanical (deformational and strength) behaviour significantly depends on the orientation of loadings to the structural elements of the mass. Shear resistance of the mass is smallest in the direction of shale interbeddings...

Paper Number: ARMA-96-2031
... discontinuous deformation analysis (DDA) technique to rock fall simulations. In order to make the method meet the practical requirements, the original DDA has been improved in the following aspects: 1). reducing error from large rigid body rotation; 2). considering damping effect due to resistance in the air...

Paper Number: ARMA-96-1951
... in support performance with variation in simple parameters such as support spacing, and support force or resistance; the use of load spreaders has also been investigated. Results are presented for one of the parameter studies, carried out under the quasi-static onditions of a normal mining procedure...

... that fracture skins have properties which have significant geotechnical and environmental implications. We make some implications about effects on the frictional resistance of fractures with fracture skins. Upstream Oil & Gas resistance hydraulic fracturing kreisel flow in porous media fracture...

Paper Number: ARMA-96-1215
... is known as the electrical contact resistance (ECR) technique. The technique was developed earlier this century to study the behaviour of metal electrical contacts (Holm, 1948). Bowden and Tabor (1950, 1964) used the technique to good effect in developing the 'adhesion theory of friction'. The theory...
