| Pump apparatus comprising a base or chassis, a power unit and a reel assembly each operatively mounted to the base or chassis, a flexible conveyor conduit and flexible service line adapted to be payed out from the reel assembly and a work head including a pump operatively connected to the conveyor conduit. The work head comprises a pump having an outlet which is operatively connected to a conveying conduit, a support frame to which the pump is mounted and a powered traction drive assembly operatively mounted to the support frame. The reel assembly comprises a reel rotatably mounted to the base or chassis, a conveying conduit and a flexible service line, each being adapted to be wound thereon and payed out therefrom. | ||||||
| 142 | INSTALLATION FOR STORING OF NATURAL GAS | EP99930080.9 | 1999-06-07 | EP1144284A1 | 2001-10-17 | JOHANSSON, Jan, Hugo |
| An installation for storing of natural gas or some other fluid comprises a lined underground storage space (10). Inside the rock wall (11) of the storage space there is a concrete layer (27) for supporting an inner impermeable lining layer (14). According to the invention, the concrete layer has a crack distribution control reinforcement layer (28) closer to the impermeable lining layer (14) than to the rock wall (11) in order to divide large cracks into smaller cracks and distribute the cracks over a larger area of the impermeable lining layer. Further, also according to the invention, there is between the impermeable lining layer (14) and the concrete layer (27) a non-binding sliding layer (29) to facilitate relative movements between the impermeable lining layer and the concrete layer. | ||||||

| The present invention provides a device providing a combined boring and placement system for jacket tubes (5), which after introduction into a borehole, for the creation of a drainage system or a pipe roof or an anchoring or a tubular pile, remain in the rock mass and which, when creating the borehole, with an extension piece (4) of a drill rod assembly (2), wherein the extension piece (4) is fitted with a non-recoverable drill bit (6) which for this purpose can be partially or fully detached from the extension piece (4), wherein the drill bit(6) is connected with the assigned extension piece(4) of the drill rod assembly(2) via a locking element (20) that secures it against rotation, which to this end is arranged in a cage (21) formed by the drill bit (6), extension piece(4) and jacket tube(5) and which can be released by the jacket tube (5) covering the cage (21). | ||||||
| 144 | MINE DEWATERING SYSTEM AND METHOD | PCT/IB2011051983 | 2011-05-04 | WO2011148285A3 | 2012-01-12 | DOWLING JEREMY; BEALE GEOFF |
| A system and method for efficiently and effectively removing water from mine areas is presented. In one embodiment, one or more directionally drilled dewatering wells are drilled into the geologic formation such that at least a portion of the dewatering well is positioned underneath the mine. In one embodiment, one or more of the dewatering wells may originate outside the perimeter of the mine so as not to interfere with mine operations. In one embodiment, a hydrogeologic assessment along with mine dewatering requirements may be used to generate a mine dewatering plan. In one embodiment, a hydrogeologic assessment along with a determination of the dewatering requirements of the mine and surrounding areas may be used to create a mine dewatering plan. In one embodiment, the mine dewatering plan provides design information pertaining to each dewatering well. | ||||||
