摘要： A site-aware controller and various sensors determine if objects are located within a safety dome surrounding a machine such as a construction vehicle. The site-aware controller compares data from the various sensors to determine if the machine or independently moveable implements located on the machine are capable of impacting objects within the safety dome and/or travel of the machine into restricted areas. Detection of objects within the safety dome can trigger alerts (e.g., visual and/or audible) to an operator of the machine of a particular situation. Detection of objects within the safety dome can also prevent further movement of the machine or independently moveable implements located on the machine to prevent impacting the objects. The system can also prevent movement of the machine into restricted areas.

摘要： A cutting unit for use with a cutting apparatus suitable for creating tunnels or subterranean roadways and the like, includes a cutting arm configured for pivotal movement around at least one pivot axis and a cutting head mounted to the cutting arm. The cutting head includes at least one rotatable cutting element for detaching material from a rock face, and a clearing arrangement mounted to the cutting arm. The clearing arrangement has a clearing blade for pushing detached rock material onto a loading table of the cutting apparatus, the clearing blade being guided by a first guiding mechanism to allow a free movement of the clearing blade in a first direction.

摘要： Systems, methods, and computer-readable medium containing instructions for controlling mining machines. One system includes an image sensor for capturing an image of a cutting face of a mine and interface sensing and control system for obtaining the image, identifying an anomaly in the image, calculating a distance between the anomaly and a reference, and using the distance to automatically instruct a mining machine control system to keep a cutter head of the mining machine within a seam.

摘要： A method of controlling a shearer is disclosed. The shearer may be configured to travel along a longwall face to extract material with a first cutting drum and a second cutting drum. The method may include setting a first cutting profile including a plurality of desired positions (Di) to be approached by the first cutting drum in a first travel direction (E). Further, the method may include determining a plurality of actual advancing vectors (vi) indicating a change of a position of the shearer resulting from advancing the shearer towards the longwall face. The method may also include determining a plurality of shearer orientations (Oi) along the longwall face. In addition, the method may include generating a second cutting profile to be approached by at least one of the first cutting drum and the second cutting drum in a second travel direction (F) of the shearer.

摘要： Methods and systems for automatically operating a continuous mining machine. One method includes automatically operating at least one actuator to position a platform supporting a cutterhead at a predetermined starting position and automatically operating the at least one actuator to advance the platform toward a cutting face until the cutterhead contacts the cutting face and at least one indicator of a physical force between the cutterhead and the cutting face exceeds a predetermined value. The method also includes automatically saving at least one coordinate of the cutting face to a computer-readable medium, the at least one coordinate based on a parameter of the at least one actuator when the indicator exceeds the predetermined value.

摘要： A method and apparatus for horizon control in a mining operation where fresh product 3 is cut from a seam 1. The cutting exposes a fresh cut product face 25. The fresh cut product face 25 is observed at a position immediately adjacent a cutter 11. Any temperature contrast regions from an IR observation between an upper limit of observation and a lower limit of observation are noted. At least one height co-ordinate position of a temperature contrast region 33 is determined and an output signal provided of the determined height co-ordinate position so that the output signal can be used as a horizon datum for horizontal control.

摘要： A method for controlling a longwall mining operation, including a face conveyor, at least one extraction machine, and a hydraulic shield support, in underground coal mining. Using inclination sensors disposed on at least three of the four main components of each shield support frame, such as floor skid, gob shield, support connection rods, and gob-side region of the top canopy, the inclination of the shield components relative to horizontal is ascertained in the direction of step. In a computer, the ascertained inclination data is compared with base data stored in the computer that defines the geometrical orientation of the components and their movement during stepping. From the comparison, a respective height of the shield support frame, at the forward end of the top canopy, is calculated as a measure for the face opening.
