... Pit flexural toppling failures have restricted overall slope angles to 37o. This paper discusses the geology, history and stability analyses of these toppling failures. The computer software programme UDEC has been successfully used to model excavation history, groundwater depressurisation and slope...

...APPROXIMATION AND RELIABILITY: A RECLAMATION AND PRELOAD DESIGN CASE HISTORY FROM PARADIP, INDIA John V Simmons1 ABSTRACT A large coal stockpiling and transhipment development at Paradip, on the Bay of Bengal, involved raising of a soft soil site using hydraulically placed dredged fill. This case...

..., peak strength and post failure behaviour of these shale materials have been studied. INTRODUCTION Borehole instability has been a significant contributor to unproductive drilling time during the history of drilling for hydrocarbons. As a consequence, drilling costs have been unacceptably high...

... ABSTRACT: An analysis is given of a case history of the deterioration of a gallery along a long wall coal panel during the extraction of the coal. Many observations have been carried out during the winning of the panel and additional information was gathered during the winning of a second coal...

... SUMMARY: The influence of history of water load on tunnel stresses is discussed from the point that Water load on tunnel is seepage body force, corresponding calculation method is proposed and an engineering project designed by this method is given as an example. ZUSAMMENFASSUNG: Die...

The uncertainties may also affect the extrapolation of the model to low stresses which are probably encountered around underground structures after long times. LABORATORY...

... OF THE PROPOSED MODEL; APPLICATION TO CASE HISTORIES The concept of the softening behavior stands in the scope of continuum mechanics and must then be handled with care in geo- technic problems, where major crack forma- tions may appear in complex geometries. In a first step we have studied the only sof- tening...
