Abstract: A recessed antenna that includes a recessed plane formed in a conductive surface. An antenna is disposed on the recessed plane. A cavity is formed beneath the recessed plane. A circuit board is disposed in the cavity. The circuit board is electrically coupled to the antenna. A cover is disposed over the antenna, the cover protecting the antenna from abrasion.

Abstract: In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.

Abstract: A system includes a slurry pipe and a pipe liner disposed within an inner diameter of the slurry pipe. At least one redundant transducer wear ladder sensor is disposed within the pipe liner. A computer controller is operatively coupled to the at least one redundant transducer wear ladder sensor via a flexible ribbon cable. A radio-wave transmitter is operatively coupled to the computer controller. A radio-wave receiver is operatively coupled to the computer controller. A power source is operatively coupled to the radio-wave transmitter and to the radio-wave receiver.

Abstract: In one aspect, the present disclosure relates to a drilling-information-management system. The drilling-information management system includes a probe assembly disposed on a drill rod, a first computer interoperably coupled to the probe assembly via a conductor disposed in a drill rod, and a second computer in communication with the first computer. The second computer includes a barcode scanner. The drilling-information management system includes a database in communication with the second computer. Drilling-project data is transferred from the database to the second computer and calibration data is transferred from the second computer to the first computer. The first computer executes a drilling plan according to the drilling-project data.

Abstract: The present application relates to a system for supporting a roof of a portion of a mine. The system includes a first plurality of stabilizing members disposed above the roof at a first elevation. The first plurality of stabilizing members originate from a first common location and terminate at a second elevation that is higher than the first elevation. The system further includes a second plurality of stabilizing members disposed above the roof and the first plurality of stabilizing members at a third elevation. The second plurality of stabilizing members originate from a second common location and terminate at a fourth elevation that is higher than the third elevation. The second plurality of stabilizing members are disposed generally perpendicular to the first plurality of stabilizing members.
