20130136545 | Nested Mine Roof Supports - This invention is directed to a mine roof support set including a plurality of nested containers. Each container in the set has a progressively smaller cross-sectional dimension to allow the containers to be nested one within the other. The plurality of nested containers allows more efficient transportation of the mine roof support set to a mine site. The containers can be separated at the mine site and filled with a load-bearing material. The containers filled with the load-bearing material are placed with their longitudinal axis between a mine roof and a mine floor. | 05-30-2013 |
20120205129 | Method of Controlling Mine Fires With Polymeric Gel - A method is disclosed for controlling a mine fire by delivering a water absorbent polymeric composition to a rock structure involved in a fire and infusing the polymeric composition into the rock structure. The polymeric composition may also be used to create a seal across a mine entry for controlling underground mine fires. | 08-16-2012 |
20110262231 | Pumpable Support with Cladding - A support for use in mines and other underground workings is provided comprising a flexible inflatable bag configured for receiving a pumpable load-bearing material. A reinforcing material is provided for supporting the bag when the bag is filled with the load-bearing material. The reinforcing material can include reinforcing plates, rings, bands or barrels positioned about the outer periphery of the bag. Alternatively, the support can be formed from a plurality of stackable barrels that are filled with load-bearing material but without the inflatable bag. The barrels can include internal reinforcing or cladding material at spaced locations along the barrels to define controlled deflection zones. According to another design, the support can be designed to be extensible. The support is inexpensive to transport, can be erected on-site and has a reinforced structure with residual yield strength. A method for supporting a mine or other underground workings is disclosed. | 10-27-2011 |
20110139157 | System and Method of Delivering Emergency Breathable Gas Supply to Underground Mines - A system for delivering a sustainable emergency supply of breathable gas to a chamber in an underground mine includes a source of breathable gas, a pipe system for transporting the breathable gas buried below the mine floor in fluid connection with the gas source, and a regulator that controls the rate at which air is released from the pipe system. | 06-16-2011 |
20110013991 | MINE SEAL WITH ADHESIVE - An explosive-resistant mine seal ( | 01-20-2011 |
20090078433 | Method of Controlling Mine Fires with Polymeric Gel - A method is disclosed for controlling a mine fire by delivering a water-absorbent polymeric composition to a rock structure involved in a fire and infusing the polymeric composition into the rock structure. The polymeric composition may also be used to create a seal across a mine entry for controlling underground mine fires. | 03-26-2009 |
