This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: LORS DE L'ABATTAGE A L'EXPLOSIF AU SEIN D'UN MASSIF ROCHEUX, LA FRACTURATION NATURELLE CONTROLE EN GRANDE PARTIE LE DEVELOPPEMENT DE LA FRACTURATION ARTIFICIELLE GENEREE PAR L'EXPLOSION. LA FRACTURATION NATURELLE ENTRAINE UNE ANIOSOTROPIE DES VITESSES DE PROPAGATION DES ONDES ELASTIQUES ET D'OSCILLATION DES PARTICULES. L'OUVERTURE DES FRACTURES EST UN FACTEUR D'ANISOTROPIE PLUS IMPORTANT QUE L'INTENSITE DE LA FRACTURATION. LA STRUCTURE DU MASSIF ROCHEUX EST MODIFIEE SUR QUELQUES METRES DERRIERE LE FRONT, LES CARACTERISTIQUES MECANIQUES DES FRACTURES ARTIFICIELLES ETANT INFERIEURES A CELLES DES FRACTURES NATURELLES, LA STABILITE DES TALUS D'ABATTAGE EN SERA AMOINDRIE

This book was released on 1994 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL PROPOSE UNE NOUVELLE METHODOLOGIE DESTINEE A EVALUER QUANTITATIVEMENT L'EFFICACITE DES TIRS DE MINES. ELLE EST FONDEE SUR LA COMPARAISON DES DISTRIBUTIONS DE TAILLE DES BLOCS DU MASSIF AVANT LE TIR ET DU TAS ABATTU APRES LE TIR. LA DISTRIBUTION DE TAILLE DES BLOCS IN SITU, APPELEE BLOCOMETRIE, EST ESTIMEE A PARTIR DE LA SIMULATION TRIDIMENSIONNELLE DES DISCONTINUITES DANS LE MASSIF. CETTE SIMULATION EST BASEE SUR UNE ANALYSE STATISTIQUE EXHAUSTIVE DES CARACTERISTIQUES DU MASSIF ROCHEUX, EN PARTICULIER DE SES DISCONTINUITES. LA DISTRIBUTION DE TAILLE DES BLOCS DES TAS ABATTUS, D'UN AUTRE COTE, EST FONDEE SUR L'ANALYSE D'IMAGES DES PHOTOS DU TAS PRISES ALEATOIREMENT. L'APPLICATION DE LA METHODOLOGIE DANS PLUSIEURS MINES NOUS A DONNE DES RESULTATS LOGIQUES CORROBORES PAR DES OBSERVATIONS SUR LE TERRAIN. NOUS AVONS PU EGALEMENT INTRODUIRE UN PARAMETRE APPELE INDICE DE FRAGMENTATION QUI TRADUIT, DE MANIERE QUANTITATIVE, L'EFFICACITE D'UN TIR. PAR LE BIAIS DE CE PARAMETRE, NOUS AVONS PU ESTIMER L'AMELIORATION DE LA FRAGMENTATION GRACE A LA METHODOLOGIE, QUI EST DE L'ORDRE DE TRENTE-SEPT POUR CENT POUR LES TROIS MINES ETUDIEES. EGALEMENT, L'ANALYSE GLOBALE DE L'ENSEMBLE DES RESULTATS OBTENUS A PERMIS LA COMPREHENSION DE L'INFLUENCE DES DIFFERENTS PARAMETRES ET L'IDENTIFICATION DES PLUS INFLUENTS. SUR LA BASE DE CES PARAMETRES, UN OUTIL A ETE DEVELOPPE VISANT A PREVOIR LES RESULTATS DES TIRS EN FONCTION DE CES PARAMETRES ET DES CARACTERISTIQUES DU MASSIF ROCHEUX

Download or read book Cambridge Yearbook of European Legal Studies Vol 13 2010 2011 written by Catherine Barnard and published by Bloomsbury Publishing. This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.
