The method further includes, controlling at least one component based on the at least one motion command. The method further includes determining, by an electronic processor, at least one predicate parameter. The method further includes determining, by the electronic processor, whether the predicate parameter is true. The method further includes, while the at least one component is being controlled based on the motion command and the at least one predicate parameter is true, receiving, from a plurality of sensors, each of the plurality of sensors positioned at one of a plurality of measurement points on the at least one component of the mining machine, a plurality of vibration data sets.

A method of determining payload data of a mining machine having a bucket and a handle. The bucket and handle are rotatably coupled via a pin and an actuator. The method includes sensing, via a sensor, a force associated with the actuator, determining, via a controller, a characteristic indicative of a rotational angle of the bucket, and determining, via the controller, payload data based on the force and the characteristic.

A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.

The present invention relates to a method for controlling a height adjustment of a stripping plate of a ground milling machine, in particular a stripping plate of a cold milling machine, during the working process, said method comprising the following steps of detecting the striking of the stripping plate against an obstacle; automatically triggering the height adjustment unit for lifting the stripping plate from a working position, in which the stripping plate is in contact with the underlying ground to be processed, to avoid a further collision with the obstacle; and automatically triggering the height adjustment unit for lowering the stripping plate back to the working position upon overcoming the obstacle.

A tunnel tunneling system includes a bolter miner, a bolter-integrated transportation machine, a transfer machine, a self-moving tail and a belt conveyor. The bolter miner includes a rack, a cutting device, a drilling device and a control device. The cutting device is arranged on the rack and is swingable in an up-down direction, and has a lowest swing angle and a highest swing angle. The drilling device is arranged on the rack, and includes a drilling rig and a sensor. The drilling rig is configured to drill a tunnel floor and/or a tunnel roof, and the sensor is configured to monitor a set parameter of the drilling rig and generate a monitoring data signal when the drilling rig is drilling. The control device is configured to receive and analyze the monitoring data signal.

A mining machine including a chassis, an actuator, a cutter drum supported by the chassis, the cutter drum driven by the actuator, a cutter bit coupled to the cutter drum, and a controller. The controller includes a processor and memory and is configured to measure a characteristic of the actuator, determine the cutter bit is worn based on the measured characteristic of the actuator, and output a signal when the cutter bit is determined to be worn.
