  • Patent number: 8100479
    Abstract: A miner communication and locating system is disclosed. Two technologies used in the system include a communicator, and a locator array that may be used with a computer. The communicator portion allows trapped miners to continually signal without physical effort that they have survived a cave-in or explosion in a direct, mechanical, and reliable manner. The locator array receives the communicator signal for use to accurately identify where the survivors are underground, and facilitate their rescue; a computer can be used to calculate the position of the communicator from information provided by a plurality of locators: global positioning system receivers may be used with the locator array.

  • Publication number: 20110297057
    Abstract: A high-strength anchor system for anchoring a support to mine strata is disclosed. The system includes an anchor plate and a connecting member on the anchor plate for connection of the support to the anchor plate.

  • Patent number: 7941974
    Abstract: A flexible, inflatable shelter is held within a storage container. The shelter can be erected rapidly, by directing compressed gas held or produced within the container, into the flexible material which will define the finished shelter. Personnel using the shelter then enter through an air lock door located in the storage container. An air lock may be alternatively provided such that is located at least partly within the deployed shelter, and so that it does not occupy substantial space in the container. The container includes supplies necessary to sustain life for an extended period. The shelter can be used to protect personnel from harmful environments caused by accidents or explosions in mines, tunnels, industrial plants, and the like. The container is compact, but allows rapid deployment of the flexible material to produce a shelter which is of approximately the same volume, or greater, than that of the storage container.

  • Patent number: 7725232
    Abstract: A method and a system for monitoring the location of a mining vehicle in a mine. The mine comprises a first and a second work area. At least one identifier (29) whose exact location is known is arranged in the first work area (18a). The location of the mining vehicle (1) is determined continuously by means of a dead reckoning. The location data, based on the dead reckoning, can be updated by means of the identifier. The location data are transmitted to a mine control system for monitoring the mining vehicle.

  • Patent number: 7614705
    Abstract: A water spray assembly especially adapted for control of dust suppression in mining machines has a manifold with one or a number of nozzles mounted thereon. The manifold provides communication between the nozzles and a manifold inlet, the manifold inlet being adapted to connect to a supply of water. The manifold with one half of a quick connect coupling cooperates with a nozzle block having a bore sized to receive at least a portion of the manifold and the other half of the quick connect coupling. The use of quick connect coupling half with the block allows easy removal and insertion of the manifold.

  • Publication number: 20090134692
    Abstract: A method and apparatus is provided for determining structural change in a mining operation. A first scan of gateroad surfaces is obtained and information of the scan profile is stored. At a later time a second scan of the gateroad surfaces is then obtained. Information of the scans can be registered and any difference noted. If the difference exceeds a threshold a warning can be provided indicating a gateroad structural change that may be hazardous. The scans can be made from a single sensor, or from multiple sensors (301, 303). In the case where the sensors (301, 303) are mounted on a gateroad traversing structure (109), the distance of spacing of the sensors (301, 303) can be used to determine when the sensor (303) has reached a position of movement or travel of the gateroad traversing structure (109) where the scan from sensor (301) was made. A distance sensor (309) can be provided to determine the distance of movement and where the scans coincide.

  • Publication number: 20090079255
    Abstract: A method of extraction of fuels and elements from coal, shale, peat and landfill seams is described which cuts the earth with only a main shaft which could measure half a meter diameter and with auxiliary narrow drillings of, say 10 centimeter diameter, widely spaced from the shaft. The coal, shale or peat seam is heated to the highest temperature of the hydrocarbon fraction desired to be extracted and the evaporated hydrocarbons are carried out of the shaft by Nitrogen gas. To enhance the extraction rate of the evaporated hydrocarbons, tonal input from two or more organ pipes vibrates the seam structure freeing the evaporated hydrocarbons allowing their escape into the shaft. As the extraction continues requiring inclusion of a greater area of the seam structure, narrow drillings are made and Liquid Nitrogen is inserted in the drillings reaching seam levels as Nitrogen gas which seeps into the seam.
