Abstract

A system and a method for increasing capacity of a battery for an electric vehicle during mining operations. The systems and methods provide a battery management software application that allows vehicle operators to designate a value for a target state of charge (SoC) of the battery before initiating a downhill tramming operation that will engage a kinetic energy capture system. The current SoC of the battery is monitored, and when it exceeds the target SoC and the vehicle is connected to a power grid, a power dump can be triggered. The power dump causes a discharge of the battery to a level corresponding to the target SoC. The vehicle can then recharge the battery with a substantially greater net charge in a subsequent downhill tramming operation.

Abstract

Apparatuses, methods, computer programs and systems for enhancing drilling accuracy for a mobile underground drilling rig are disclosed. With the disclosed inertial measurement unit (IMU) (11), a vertical orientation error caused by a drilling boom (3) and/or a feed rail (5) bending may be directly measured and corrected, for example. A position error caused by the drilling boom (3) bending may be corrected or at least reduced by using the IMU (11) data in compensation data/models. Such combined/new compensation data does not depend on drilling direction, such as face drilling, ramp drilling, and cross-cut drilling. Furthermore, the IMU (11) may be used to measure a change in a feed angle caused by contact forces between the feed rail (5) and rock, thereby further improving overall mining accuracy.

Abstract

An arrangement and method of sensing tangential velocity of surface of an object. The arrangement comprises a sensor (S) at a sensing point (SP) for measuring the tangential velocity at least in one sensing direction (SD). The sensor comprises a magnetizing element (10), a sensing element and a sensing gap (SG). The sensing element comprises one or more sensing wires (6) which are arranged to the sensing gap in transverse direction relative to the sensing direction. The magnetizing element generates a magnetic field (2) so that line of flux passes through the sensing gap. Electric voltage is induced to the sensing wire when the object moves. The object is made of hysteric ferromagnetic material and when a rapid change in movement of the object occurs, then the magnetic field deflects due to hysteresis causing thereby induction of the electric voltage. The sensed electric voltage is directly proportional to the tangential velocity.
