A protective device, rock drilling unit and method. The protective device (9) comprises a protective casing (10) mountable around a drilling tool (8). The protective casing comprises at least openable and closable rigid chain (11) provided with parallel chain members (15a, 15b). The chain members comprise grip elements (16) which can interlock with each other and form a closed structure. By disengaging the grip elements, the protective casing can be opened. The opening and closing is executed in response to movements of a rock drilling machine (6) in a drilling direction (A) and in a reverse direction (B).

A method for condition monitoring of a mining vehicle. The method comprises controlling a hydraulic circuit to pressurize a lifting cylinder for changing a position of a dump box relative to a body of the mining vehicle, controlling a respective pressure release valve to open the hydraulic circuit for depressurizing the lifting cylinder, measuring a loading applied by the dump box to the body of the mining vehicle both in response to changing the position of the dump box relative to the body of the mining vehicle and in response to control the pressure release valve to open the hydraulic circuit, and determining, based on the said loading measurements, a state of the pressure release valve in response to control the pressure release valve to open the hydraulic circuit for depressurizing the lifting cylinder.Additionally, a system for condition monitoring of the mining vehicle.

Example embodiments of the present disclosure relate to controlling a mining machine. An apparatus may comprise: at least one processor; and at least one memory including computer 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 an inertial measurement signal from a sensor of the mining machine; determine a motional status of the mining machine indicative of whether at least one part of the mining machine is stationary based on at least one control signal provided by control circuitry of the mining machine or based on at least one sensor signal received from at least one other sensor of the mining machine; and perform calibration of the inertial measurement signal, in response to determining that the motional status of the mining machine is indicative of the sensor being stationary.

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.
