  • Publication number: 20220349304
    Abstract: A mining system with an inertial guidance system configured to enable precise excavation of geological material without a need to advance a survey line over a long distance and/or nonlinear excavation path, thereby maximizing productivity of the mind by minimizing a width of un-mined material necessary for support between adjacent excavation paths and minimizing equipment downtime.
    Type: Application

  • Patent number: 7686400
    Abstract: The invention provides, in one embodiment, a detector for a miner comprising a gamma sensing element and a light sensing element coupled to the gamma sensing element. According to the embodiment, the detector is mounted on a rotary cutter of a boring-type continuous miner such that the gamma sensing element has a view of a geologic formation being mined. A mining control system is also provided, comprising a miner having at least two rotary cutters and a gamma detector on each of the at least two rotary cutters for receiving gamma emissions from a geologic formation. The mining control system also provides an accelerometer and a rate gyro, wherein the accelerometer and the rate gyro correlate the received gamma emissions with positions of the at least two rotary cutters, and a central module that utilizes the correlated readings to determine whether the cutters should be moved.
