The rate of penetration of water-jet drill is shown to be related to the grain size of the rock and its derived function, to the surface area of grain boundaries per unit volume, and also to the volume of cracks per unit volume of rock.L'\ue9tude d\ue9montre que la vitesse de p\ue9n\ue9tration d'une foreuse \ue0 jet d'eau dans une roche est en corr\ue9lation avec la granulom\ue9trie de la roche et sa fonction d\ue9riv\ue9e, avec la surface sp\ue9cifique du contour des grains par unit\ue9 de volume, et aussi avec le volume des fissures par unit\ue9 de volume de la roche.Peer reviewed: YesNRC publication: Ye
