This issue of the journal contains reports by equipment suppliers and summary studies: (1) Analysis of anchorage at a single point or distributed over several points (Sinou, P and Tincelin, E); (2) Study of shear by rods (Aznar, JJ and Panet, P); (3) First empirical studies of the behaviour of bolted roofs (Leonet, O and Tincelin, E); in another report, Sinou, P and tincelin, E propose an original theoretical interpretation of the various types of behaviour of supporting ground, which lead to buckling. Comments result in the setting up of practical regulations immediately usable. Lastly, a study is presented of the different roles of bolting in various terrain geometries. An equation is given for selecting parameters, and mention is made of measures for the control of the techniques described. (TRRL)
