A mixer truck water spray bar for suppression of dust clouds is disclosed. The mixer truck water spray bar generally includes an entrance chute configured to receive water from the drum via the mixer chute that is removably attachable to the mixer chute and a manifold attached to the entrance chute that is oriented substantially perpendicular to the entrance chute and is configured to receive water from the entrance chute via an entrance opening and comprises a plurality of apertures configured to externally distribute water received through the entrance opening through the apertures without the use of a pump.

An autonomous truck loading system can have a database that stores a plurality of elementary behaviors for various phases of a process of loading the autonomous truck by the one or more loaders. The stored elementary behaviors can include predetermined maneuvers for the autonomous truck, sensing behaviors; and logic behaviors. An operator can select multiple ones of the stored behaviors via user interface. A controller can assemble the selected behaviors together into an operation script for loading of the autonomous truck by a loader. The controller can control the autonomous truck to perform the operation script.

A fluid spray for an underground roof support includes a first housing portion, a spray outlet, a second housing portion formed integrally with the first housing portion, and a service port. The first housing portion includes an elongated shaft having a first end, a second end, and a first fluid passage extending between the first end and the second end. The spray outlet is positioned adjacent the second end of the shaft. The second housing portion is positioned adjacent the first end of the shaft. The second housing portion includes at least one port and a second fluid passage between the at least one port and the first fluid passage. The service port is aligned with the first fluid passage, and the service port is selectively opened to provide access to the first fluid passage from the first end of the first housing portion.

A system can have a database that stores a plurality of behaviors for various operational phases of an autonomous truck. The stored behaviors can include predetermined maneuvers for the autonomous truck, sensing behaviors, and logic behaviors. An operator can select one or more of the stored behaviors via a user interface. A controller can control the autonomous truck to perform the selected behaviors, for example, by assembling the selected behaviors together into an operation script. In some embodiments, performance of the selected behaviors can be used to load the autonomous truck.

The present invention relates to a dust suppression system for use in a container, and a misting apparatus therefor. In one form, the dust suppression system comprises at least one misting apparatus for contributing to the creation of a mist layer for preventing the escape of the dust from the container, the misting apparatus comprising a means for generating an airflow, and a means for producing a mist in the airflow so that the mist is carried by the airflow.
