description A method for measuring the movement of boundaries between different portions of a heterogeneous rock body is disclosed. The method comprises placing a plurality of blast movement monitors 109 in a rock body prior to blasting and noting the position of each blast movement monitor. The rock body is then blasted to break it up into a plurality of pieces. Thereafter the position of the blast movement monitors 109 is located and based on this the boundaries of rock portions can be adjusted to account for the blast. This leads to a more accurate reporting of different ore bodies to the appropriate processor in a heterogeneous rock body. An apparatus for carrying out the method is also disclosed. The apparatus comprises broadly a said monitor 109 and a receiver. The monitor I comprises a transmitter 109 received within a casing 111 that in turn is received within a housing 126. Further the casing 111 can move within the housing 126 and self right so that it always transmits its signal in an upright direction. Procédé de mesure du mouvement des frontières entre différentes parties d'un rocher hétérogène. Le procédé comprend le positionnement de multiples moniteurs de mouvement d'explosion (109) dans un rocher avant de le faire exploser et la prise en note de la position de chaque moniteur de mouvement d'explosion. Le rocher est alors dynamité afin qu'il soit brisé en de multiples morceaux. La position des moniteurs de mouvement d'explosion (109) est alors déterminée et les frontières des parties du rocher peuvent alors être ajustées. Cela permet de dresser un bilan plus précis des gisements de minerai pour le processeur approprié dans un rocher hétérogène. L'invention concerne aussi un appareil de réalisation du procédé. L'appareil comprend globalement un moniteur (109) et un récepteur. Le moniteur I comprend un transmetteur (109) intégré à une enveloppe (111) qui est à son tour intégrée à un boîtier (126). De plus, l'enveloppe (111) peut se déplacer dans le boîtier (126) de sorte qu'elle puisse transmettre le signal en direction redressée.
