Paper presented at the ISRM Regional Symposium - EUROCK 2014, May 27–29, 2014
Paper Number: ISRM-EUROCK-2014-035
... Abstract One of unknown rock mass properties in rock mechanics is the elastic modulus. Many researchers have proposed a variety of methods to estimate this rock mass property. One of the method is 3D numerical model calibration to obtain the key mechanical properties of the rock mass. At Mae...

... Pickard of Shell. However, one only has to look at the so-called ‘high potential incidents’ (HPIs) promulgated by APPEA to see the gap between what is published (APPEA various) and MAE precursors like gas releases ( NOPSEMA 2012a,b ; cf PSA 2012 ). While publishing HPIs is commendable, at best only four...
