Abstract: The present invention relates to a method, and an arrangement for mounting bolts in a material. The method comprises: storing actual data representing the actual positions of bore holes having been bored in the tunnel wall by a drill rig (300), a control unit (800) instructing a bolting device (200) to mount bolts in the bore holes based on the stored actual data.

Abstract: An arrangement for storing thermal energy, including a shaft (1) and at least one tunnel (2), the shaft (1) and the tunnel (2) being in fluid communication with each other. The tunnel (2) includes at least a first (2a), a second (2b), and a third (2c) tunnel section. The second tunnel section (2b) is arranged between and connected to the first (2a) and third (2c) tunnel sections. The second tunnel section (2b) is sealed off at an end (4) connected to the third tunnel section (2c), and the third tunnel section is further connected the shaft (1). The shaft (1) and first (2a) and third (2c) tunnel sections hold fluid for thermal storage. The second tunnel section (2b) is an expansion space should a volume of the fluid expand beyond a volume of the shaft (1) and the first (2a) and third (2c) tunnel sections.

Abstract: An arrangement for storing thermal energy has at least two tunnels (1a, 1b) for holding a fluid. The tunnels (1a, 1b) are connected to each other by at least one channel (2), such that fluid communication is allowed between the tunnels (1a, 1b). Each of the inner tunnel (1a) and the outer tunnel (1b) is configured as a helix, the inner tunnel (1a) forming an inner helix and the outer tunnel (1b) forming an outer helix.

Abstract: An arrangement for storing thermal energy, having at least one subterranean chamber for holding a first fluid is provided. A passage holding a second fluid is extended outside at least a part of the chamber. At least one channel is arranged to allow fluid communication of the first fluid between different sections of the chamber, and/or allow fluid communication of the second fluid between different sections of the passage.

Abstract: A method for operating an arrangement (1) for storing thermal energy where the arrangement (1) includes an energy storage (2) having a temperature gradient. The method involves retrieving energy at a first temperature (T1) from the energy storage (2) for use in a first heat-absorbing system (3), such that free space is created in the energy storage (2) for energy at a second temperature (T2). The second temperature (T2) is higher than the first temperature (T1).

Abstract: The present invention relates to a nozzle (100) for distribution of a fluid having a speed. The nozzle (100) defines a plurality of flow passages (150, 160, 170), at least one of the plurality of flow passages (150, 160, 170) is a central flow passage (160) and at least a first and a second of the plurality of flow passages (150, 160, 170) are outer flow passages (150, 170). The outlets (152, 172) of the outer flow passages (150, 170) are arranged on either side of the outlet (162) of the central flow passage (160). The second outer flow passage (170) has an inlet area (235) which is smaller than an outlet area (a3). A central axis of the inlets (210, 220, 230) is substantially perpendicular to a central plane of the outlets (152, 162, 172).
