    摘要: Apparatus for the measurement of ore in mine ore benches or ore stockpiles is disclosed, the apparatus comprising: a mobile platform, defining a platform zone, wherein the mobile platform is positionable on or above a mine ore bench or stockpile; and at least one magnetic resonance (MR) sensor comprised in the mobile platform. The MR sensor includes a main loop and a drive loop located above the main loop. A magnetic resonance sensor control system is provided and configured to control at least one of: the positioning of the at least one MR sensor relative to the platform zone and/or mine ore bench or ore stockpile; the positioning of elements comprised in the MR sensor relative to each other; electromagnetic suppression characteristics of the at least one MR sensor; and/or sensitivity of the at least one MR sensor as a function of distance of the sensor from the mine ore bench or ore stockpile.
