Paper presented at the ISRM Regional Symposium - EUROCK 2014, May 27–29, 2014
Paper Number: ISRM-EUROCK-2014-134
.... Selecting the most appropriate excavation method is not simple as it is depending of several parameters and particular conditions. The purpose of this paper is to make a review of the parameters involved in the selection of proper excavation method. The applicability and level of convenience of each...

... that three factors can have on results of a numerical analysis. These are 1) the Digital Elevation Model (DEM) resolution; 2) the morphology and substrate influence on the rheology selection; and 3) the role of the entrainment process. The Baio Dora debris flow is back-analysed to this aim. Obtained...

.... Exceptionally long horizontal drilling can create significant wellbore stability issues, which are stress-induced and time-dependent, from fluid-formation interaction. Complex multistage hydraulic fracture designs require extensive geomechanical information for optimization, such as selection of well placement...
