20110250021 | METHOD AND ARRANGEMENT FOR DETECTION AND DESTRUCTION OF TUNNELS - A method and arrangement for destroying tunnels. A subterraneous, vertical shaft is excavated until a tunnel preventing depth. After liquid is introduced to the shaft, a shaft liner is penetrable by the introduced liquid when a tunnel is present in the vicinity of said shaft, due to the considerably larger pressure of the introduced liquid relative to the bearing capacity of soil interposed between the tunnel and shaft. The tunnel is then flooded and destroyed following passage of the liquid through the liner. A system for detecting and destroying tunnels in the proximity of a security-sensitive facility comprises a hollow member anchored to the upper soil surface adjoining each shaft, a sensor having a unique address mounted on a corresponding hollow member for generating an electrical output when the liquid level has been reduced more than a predetermined level, and a computer in data communication with each of the sensors. | 2011-10-13 |
20110250022 | ROOF BOLT ANCHOR WITH CAMMING ELEMENT - A bolt anchor is comprised of a camming element and sleeve. The camming element is generally cylindrical, but with a larger midsection and reduced diameters at each end. The camming element includes a threaded bore along its axis and at least one stop near one end. The sleeve has a round collar with leaves extending from the collar parallel to the axis of the collar and each other. The stop maintains the assembly of the camming element and sleeve. Prongs on the sleeve prevent the retraction or turning of the bolt anchor when a bolt is installed in a hole. Reduced material thickness associated with the leaves produces hinges which allow the leaves to be more easily deformed outwardly. Inserting a bolt and anchor assembly into the hole and turning the bolt pulls the camming element into the sleeve and creates a wedging effect in the hole. | 2011-10-13 |
20110250023 | ENGINEERED METAL CRIB FOR USE AS A SUPPORT STRUCTURE - This invention provides improvements through an engineered metal crib element for construction of cribs in mines to provide support between two surfaces and use of crib elements to construct cribs.
