    摘要: A system for detecting a potential collision between an object and a mining machine, the system comprising: a sensor, a first strobe light and a second strobe light, and an electronic processor configured to identify a virtual perimeter around at least a portion of the mining machine, identify a plurality of collision zones, the plurality of collision zones including at least one immediate collision zone and at least one potential collision zone, receive a signal from a sensor indicating detection of the object in one of the plurality of collision zones, determine, based on the signal, whether the object is in the immediate collision zone or the potential collision zone, generate, in response to determining that the object is in the potential collision zone, a first indication, and generate, in response to determining that the object is in the immediate collision zone, a second indication different than the first indication.

    摘要: A cable handling system for a longwall mining machine is disclosed. The longwall mining machine includes a shearer configured to move along a pan line to mine material along a mine face. The cable handling system includes a service line configured to carry one or more supply lines to the shearer for facilitating shearer operation. Further, a plurality of interconnected trays accommodates the service line. Moreover, a controller is configured to determine a profile of the pan line; detect one or more parameters associated with the service line in relation to the profile of the pan line; and determine a likelihood of at least a portion of the service line dislodging from the plurality of interconnected trays based on the one or more parameters exceeding a predefined threshold.

    摘要: Methods and systems for detecting a person located around a piece of equipment. One system includes processor configured to define a first virtual zone around a piece of equipment, determine a location of a person, and define a second virtual zone around the person at the location. As the location of the person changes, the processor is further configured to determine a direction of travel of the person, and automatically modify the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distance. In response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, the processor is configured to perform at least one action.

    摘要: A drive system for driving an endless chain of a mineral mining installation employs one or more chain wheels each driven by an electric motor and gearing including planetary gearing. The planetary gearing has a ring gear which can be held stationary to permit drive to be transmitted. The ring gear is coupled through a clutch, reduction gearing and a braking device to another load-balancing electric motor. Load sensors in the reduction gearing disengage the clutch in the event of overloading. The ring gear is automatically held stationary by the braking device when the load-balancing motor is inoperative. When the motor is switched on the braking device is released to permit the motor to rotate the ring gear in one direction or the other at controlled speed to vary the transmission ratio and effect load balancing.
