A method of constructing underground galleries using a pneumatic transfer system and a stratum disposal method are provided, wherein in constructing disposal galleries, mountain tunnels or the like in a stratum disposal site or in performing stratum disposal of waste matter, the carrying-out of excavation chips or the like and carrying-in of materials and equipment or the like and the carrying-in and positioning of waste matter can be effected safely, quickly and reliably at low cost, and the quality of buffer material for waste matter can be secured. In construction, an air carrying pipeline 10 is used while extending the air carrying pipeline 10 downward as desired during the excavation of a vertical shaft 2a so as to carry out vertical shaft excavation chips a to the ground and carry in materials and equipment including vertical shaft spray concrete b to the underground site. Alternatively, the vertical shaft itself is used as the air carrying pipeline 10, and by using the air carrying pipeline 10 extending from the vertical shaft 2a to an underground gallery 3, excavation chips a from the underground gallery 3 are carried out to the ground and materials and equipment for the underground gallery are carried in to the underground site. In operation, the air carrying pipeline 10 is used to carry in a carrying container 11 having the waste matter A and a buffer material B, which are integrated together, stored therein, to the underground side, and the integrated waste matter A and buffer material B are positioned and buried in a disposal hole 7.

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 invention relates to a method in operating a lined cavern provided for the storage of gas, such as natural gas, coming from a pipeline, in the form of gas. During filling of the cavern with gas to a nominal pressure, at least a portion of the gas is withdrawn from the cavern and recirculated to the cavern under cooling and without substantial compression. The invention also relates to a method in operating a lined cavern provided for the storage of gas, such as natural gas, coming from a pipeline, in the form of gas. In the withdrawal of gas from the cavern for introduction into the pipeline, a portion of the withdrawn gas is, before the pipeline, recirculated to the cavern under heating and without substantial compression.

The invention provides caverns and methods for producing caverns in bedded salt deposits. In a preferred method, a first bore hole (19) is drilled into the salt formation (10) and a cavity (13) for receiving insolubles is leached from the salt formation (10). Thereafter, at a predetermined distance away from the first bore hole (19), a second hole (17) is drilled towards the salt formation. The drill drills through the salt formation in a horizontal direction until it instersects the cavity (13) for receiving insolubles. This produces a substantially horizontal conduit (20) from which solvent is controlledly supplied to the surrounding salt formation, leaching the salt and producing a concentrated brine which is removed through the first bore hole (19). Insoluble are collected in the cavity (13) for receiving insolubles. By controlledly supplying solvent, a horizontal cavern is produced with two bore holes (17 and 19) extending therefrom.
摘要:
Procédé de construction d'un emplacement de stockage de produits liquides dans des formations rocheuses, cet emplacement comprenant une première cavité et une pluralité de deuxièmes cavités situées à l'extérieur de la première cavité. Selon ce procédé on forme d'abord un tunnel (7) en pente depuis la surface du sol jusqu'à un point donné dans la formation rocheuse. On ouvre ensuite à la mine à partir de ce point donné un deuxième tunnel en pente (22) qui serpente dans l'emplacement définitif de stockage et descend en une pluralité de tournants jusqu'au niveau du fond (11) de la première cavité définitive. Des tunnels primaires horizontaux (T1-T6) sont alors ouverts à la mine à partir du tunnel sinueux à une pluralité de niveaux. A partir des tunnels primaires sont ensuite ouverts à tous les niveaux une pluralité de tunnels secondaires horizontaux qui s'étendent vers l'emplacement de la première cavité définitive (1) et définissent un certain nombre de gradins rocheux (P1-P6), et on creuse ensuite à la mine la première cavité, de manière à s'étendre le long ou jusqu'au niveau des parties les plus basses des deuxièmes cavités définitives (2). On ouvre ensuite facultativement un ou plusieurs tunnels en pente, qui sont dirigés vers le centre de la partie la plus basse de la première cavité. On creuse ensuite à la mine les deuxièmes cavités en faisant sauter les gradins rocheux (P1-P4) situés entre des tunnels secondaires superposés, en commençant par le gradin le plus bas et en continuant vers le haut avec les gradins restant l'un après l'autre, la masse rocheuse abattue (16) retombant vers le bas, facultativement au travers des tunnels de glissement, étant transportée jusqu'àu niveau du sol (Fig. 10).

Durch die Verwendung einer Mischung von hochverdichteten Formkörpern aus bindigem Material, wie z.B. Pellets aus Bentonit, und inerter Zwickelfüllung, wie z.B. sehr feinkörniger Quarzsand, lassen sich auch untertage Verschlussbauwerke von hoher Dichte und hoher Wasserundurchlässigkeit ohne zusätzliche Verdichtung erstellen.

A system for high-pressure natural gas storage includes at least one underground bored tunnel, suitable for holding natural gas under pressure and a process for storing natural gas under pressure.
摘要:
The underground fluid management system (1) has an accumulator (2) formed by a cavity of the mine (M), another accumulator (3), whose base is arranged above the former accumulator and a geothermal unit (7) for operating a pump (P). The latter accumulator extends such that it projects from a non-contaminated layer into a contaminated layer. Independent claims are also included for the following: (1) a waterworks with an output system for providing drinking water and industrial water; and (2) a method for operating a fluid management system for mines.
