Sandvik Mining and Construction

A cable guiding device, a mining vehicle, and a method of guiding a trailing electric cable of an electrically powered mining vehicle. A cable guiding device (17) is for guiding a trailing electric cable (14) of an electrically powered mining vehicle (1). The cable guiding device (17) comprises a cable guiding tail (18) which has an elongated arm configuration mountable to the electrically powered mining vehicle (1). The cable guiding device further comprises a cable guiding assembly (19) mounted to the cable guiding tail (18) and comprising guide rollers (28) for guiding the trailing electric cable (14). The cable guiding device further comprises a force assembly (100), being coupled to the cable guiding assembly (19) and/or the cable guiding tail (18), and configured to pull the trailing electric cable (14) out from the cable reel assembly (16) by providing a force to a portion of the trailing electric cable (14) that is unwound from the cable reel assembly.

An underground mining vehicle comprises a load carrying element, a hydraulic operating circuit comprising at least one hydraulic cylinder for operating the load carrying element, and a control system for controlling an operation of the hydraulic operating circuit. The control system comprises at least one data acquisition device for collecting operational data representing an operation of the at least one of the hydraulic operating circuit and the at least one hydraulic cylinder. The control system comprises a control unit configured to control the operation of the hydraulic operating circuit to control, based on the collected operational data, a speed of motion of the at least one hydraulic cylinder for providing a controllable cushioning effect for the at least one hydraulic cylinder.Additionally, a method for controlling an operation of an underground mining vehicle.

A bolting rig and method for rock reinforcing. The bolting rig (1) comprises a bolt storage (12) supported at a front part of a carrier (2) and being movable to a pick-up position (PP). A bolting unit (4) comprises a bolt rack (11) and is positioned to the pick-up position for replenishing several rock bolts (5) simultaneously from a delivery plane (16) of a bolt storage.

A bolting rig and method for rock reinforcing. The bolting rig (1) comprises a movable carrier (2), a bolting boom (3) mounted to a boom mounting point (16), and a bolting unit (4) mounted to the bolting boom. There is also a cable reel arrangement (9) which comprises a cable reel (18) loaded with would cable (26). The cable reel arrangement is located at a front part of the carrier and is in front of the boom mounting point.

A method comprises: detecting the mining machine to have lost connection to an external safety system; controlling the mining machine to stop movement of at least a movable carrier of the mining machine while maintaining a motor of the mining machine in operation, in response to detecting the mining machine to have lost the connection to the external safety system; determining not to cause the motor of the mining machine to enter a non-operational state, in response to detecting the mining machine to have re-established the connection to the external safety system within a first predetermined time period; and causing the motor of the mining machine to enter the non-operational state, in response to detecting the mining machine not to have re-established the connection to the external safety system within the first predetermined time period.

Method for monitoring performance of a dust collector of a drilling apparatus, comprising:- providing suction by a suction device for drawing air from a drill hole into a dust collector,- collecting dust with a filter from the air drawn from the drill hole,- monitoring input power of the suction device,- transmitting input power data of the to a controller,- selecting an action automatically by the controller if the input power is decreased.

Example embodiments relate to configuring a route for a mining machine. An apparatus may comprise: at least one processor; and at least one memory including program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive a requested end position of the mining machine and a requested orientation of the mining machine at the end position; determine a route for navigation of the mining machine to the requested end position such that the mining machine is configured to be in the requested orientation when reaching the requested end position; extend the route from the requested end position in a predetermined driving direction of the mining machine to a position of a wheel block; and transmit a configuration of the extended route to the mining machine.
