    摘要: An underground radio communications and personnel tracking system uses a cap-lamp worn by a miner when underground in a mine. A cap-lamp transceiver provides voice and text communication on ultra-low frequency (ULF) to ultra-high frequency (UHF) carrier frequencies and modulation adapted by programming of a software defined radio to making selective and agile radio contacts via through-the-earth, conductor/lifeline, coal seam, tunnel, and ionosphere/earth-surface waveguides for transmission of electromagnetic waves. These waveguides comprise layered earth coal and mineral deposits, and manmade mining complex infrastructures which serendipitously form efficient waveguides. Ultra-Low Frequency F1/F1 repeaters are placed underground in the mine, and providing for extended range of communication of the cap-lamp transceiver with radios and tracking devices above ground of the mine.

    摘要: A coal bed anomaly detection and imaging system comprises a synchronous transmitter and receiver that are separated by a geologic structure with embedded and hidden anomalies. The receiver is housed in a shuttle body that can be pumped into a borehole by water or air pressure. The shuttle may itself employ hydraulic inching mechanism to move within the drillhole. Signal measurements are reported out over a fiberoptic pigtail. A separate radio signal path provides synchronization between the transmitter and receiver. The receiver shuttle is tethered by this fiberoptic pigtail, and it can be withdrawn from the borehole by the tether.

    摘要: A coal mining operation begins by using directional drilling to bore several horizontal shafts through a coal deposit with its natural overburden still intact. Any methane gas permeating the coal deposit is pumped out and preferably sold as natural gas to commercial and residential customers, or used locally in support of mining operations. The methane gas evacuation continues until the concentrations are reduced to safe levels for mining. But before mining begins, ground penetrating radar equipment is lowered into the boreholes for electronic imaging studies of the coal deposit. One borehole is used for a transmitter and another for a receiver. Many measurements are made at a variety of frequencies and equipment positions within the boreholes. Such studies estimate the electrical conductivity of the surrounding material, and thereby give clues where and how much coal is actually deposited. Assessments of the coal reserve are then developed from this information, and used for business planning and mine engineering.

    摘要: A method for determining the thickness of a layer of material, such as soil, wood, ice or coal, that utilizes a microstrip antenna as a thickness measuring sensor. The sensor is positioned over the layer and a value for a parameter of the antenna such as conductance or resonant frequency is measured. The value is compared to a calibration table of values and the thickness of the layer is determined by interpolation. Alternatively, the value is compared to a control value to initiate a decision process. The decision could be that a layer of ice is building up on a wing of an aircraft or that an explosive device is buried under a layer of soil.

    摘要: An apparatus and method for detecting vertically or horizontally oriented underground electrical conductors such as electrical wiring or rails in tunnels thin conducting ore veins surrounded by less conducting rock, or boreholes filled with conductive water or lined with a conductive casing. The apparatus includes a surface or downhole transmitter and a downhole receiver connected to a coherent frequency source unit by fiber optic cables. The source unit generates two phase synchronized frequency signals in the range of one hundred to three hundred kHz. The receiver includes a vertical or horizontal magnetic dipole antenna, e.g. a ferrite rod antenna, and the transmitter includes a vertical or horizontal magnetic dipole antenna in the downhole configuration or at least one long cable or loop antenna in the surface configuration. The method includes generating a first electromagnetic field which induces current flow in the electrical conductor surround by the less conducting rock and then detecting a component of a second electromagnetic field generated by the induced current flowing in the conductor, as a received signal at the receiver. The received signal is processed by synchronous detection in the coherent frequency source unit so that phase shift and amplitude data can be extracted from the received signal. The method can also be used to determine if the distance separating two drillholes is constant. In this case, the preferred operating frequency is above 10 MHz. 2

    摘要: A security device for determining the opening or closed condition of an access gate, such as a door or window hinged within an opening in a wall, has a detector unit mounted on the wall adjacent to the opening and linked to a remote control unit by a radio transmitter in the detection unit and a radio receiver in the control unit. The detection unit has an infrared generator and an infrared detector isolated from the generator, the detector and generator confronting a reflector mounted on the access gate when the access gate is closed. The reflector is translated from the field of the infrared generator when the access gate is open. The infrared generator is excited by a pulse generator to produce pulses of infrared radiation, and the scattered radiation from the reflector is detected by the infrared detector to produce electrical pulses coincident with the pulse generator. A coincidence circuit determines the presence of the detected pulse, and the absence of coincidence results in the transmission of a radio wave from the detector unit to the control unit to establish alarm conditions.

    摘要: A method of land surveying that electronically registers together multi-layer underground and surface images of a surface volume with buried utilities and other infrastructures. Such method further comprises assembling and presenting the combination to a device in the field that visually guides crews in their safe digging of the ground nearby. The orienting, scaling, and registering of a first image layer is to a standardized orientation and scaling on a map of a photograph of a land surface from a zenith point in space above. Then the orienting, scaling, and registering of a second image layer is made to the standardized orientation and scaling on the map. This layer is a result of a ground penetrating radar investigation of buried objects point-by-point in an immediate search area of a corresponding ground surface. Underground buried objects and utilities are thereby located to make safe digging nearby.
