摘要: A method of monitoring a longwall shearing mining machine in a longwall mining system, wherein the shearing mining machine includes a shearer having a first cutter drum and a second cutter drum, includes receiving, by a processor, shearer position data over a shear cycle. The horizon profile data includes information regarding at least one of the group comprising of a position and angle of the shearer, a position of the first cutter drum, and a position of the second cutter drum. The method also includes analyzing the shearer position data, by the processor, to determine whether a position failure occurred during the shear cycle based on whether the computed horizon profile data was within normal operational parameters during the shear cycle, and generating an alert upon determining that the position failure occurred during the shear cycle.

摘要: 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.

摘要: The present invention relates to a self-propelled construction machine, in particular a road milling machine, a recycler or a surface miner, comprising a machine frame 1 supported by a chassis 2 which comprises front and rear running gear 3, 4. A working device 5 is arranged on the machine frame 1 and comprises a working roller 17 for working the ground. Lifting devices 15, 16 are associated with the individual running gears 3, 4 and can each be retracted or extended for raising or lowering the running gears with respect to the machine frame. In addition, the construction machine comprises a control unit 20 for actuating the lifting devices 15, 16, which control unit comprises a lifting position measuring device 22 for detecting the lifting position of the lifting devices and a tilt detection device 23 for detecting the tilt of the machine frame 1 transversely to the working direction A of the construction machine. The control unit 20 provides a first mode of operation for working the ground and a second mode of operation for moving the construction machine, and is characterized in that, in the second mode of operation, the lifting devices 15, 16 associated with the individual running gears 3, 4 or wheel are actuated in such a way that the machine frame 1 is substantially levelled transversely to the working direction A of the construction machine, the ground clearance b preferably being at a maximum or the distance not falling below a minimum distance.

摘要: A replaceable tool support is disclosed. The tool support may be configured to be mounted to a base member of a cutting head, which may be mountable to a tool drum used in hard rock mining applications. The tool support may have an annular body having a first end face side. The tool support may also have a plurality of cutting bit carriers disposed spaced apart from each other on the first end face side. In addition, the tool support may have a plurality of cutting bits. Each of the plurality of cutting bits may be rotatably supported by one of the plurality of cutting bit carriers.

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 self-propelled building machine, especially a road cutting machine or a surface miner, has a machine frame and a chassis, comprising running gears resting on the ground. In addition, the present invention relates to a method for operating such a building machine. In an operating mode for adjusting the working depth of the working device the imposed weight applied by the building machine on the running gear is measured, whereby depending on the imposed weight either a controlled or an uncontrolled lowering of the building machine is indicated. A measuring device comprises a sensor for measuring the weight imposed by the building machine on at least one of the running gears. Depending on the measured imposed weight, a signal is generated indicating an uncontrolled lowering of the building machine, if the imposed weight falls short of a predetermined value and/or a signal indicating a controlled lowering of the building machine is generated if the imposed weight reaches or exceeds a predetermined threshold value.
