摘要:
The destruction of a well as a result of the movement of a subsiding subterranean rock formation (24) penetrated by the well bore (22) is delayed by constructing the well with a slot (28, 34, 36) cut into the subterranean formation in a direction opposite the direction (26) of movement of the formation towards the well bore, whereby the well bore extends through the slot as the subterranean formation moves.

A method of constructing underground galleries using a pneumatic transfer system and a stratum disposal method are provided, wherein in constructing a disposal gallery of a stratum disposal site and tunnels such as mountain tunnels or in performing stratum disposal of waste matter, the carrying-out of excavation chips or the like, the carrying-in of materials and equipment or the like and the carrying-in and positioning of waste matter may be effected safely, quickly and reliably at low cost, and the buffer material quality for waste matter may be secured. In construction, an air carrying pipeline (10) is used while extending the air carrying pipeline (10) downward as desired during excavation of a vertical shaft (2) 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) with the waste matter (A) and a buffer material (13) integrated together and stored therein, to the underground site, and the integrated waste matter (A) and buffer material (B) are positioned and buried in a disposal hole (7).

Verfahren zum Abbau von Böden, wobei eine um ihre Längsachse rotierende Aufdüslanze (5) bis zu einem Bohransatzpunkt (17) vorgetrieben wird und wobei mit der Aufdüslanze (5) ein fluides Medium unter hohem Druck in den Boden eingedüst wird. Das aufgelockerte Erdreich wird abgefördert und die Aufdüslanze (5) wird unter Bildung eines Aufdüsraumes aus dem Boden gezogen. Die Ausdehnung des Aufdüsraumes wird ermittelt. In Abhängigkeit von dieser Ausdehnung wird ein Raster von Bohransatzpunkten mit der Maßgabe festgelegt, dass benachbarte Aufdüsräume aneinander angrenzen oder einander überlappen. Die Bohransatzpunkte (17) des Rasters werden nacheinander automatisch von der Aufdüslanze angefahren.
摘要:
The invention relates to a method for sinking or introducing cavities in rock, wherein the face of the cavity (2) is melted using electrical plasma generators. In order in such a method to produce an energy density at the face of the cavity (2), said energy density being sufficient to completely or partially evaporate the in-situ stone, the invention proposes arranging a heat shield (4) immediately over the face of the cavity (2), said heat shield (4) forming with the face of the cavity (2) a dynamic pressure space (7) in which a temperature of more than 2000°C is established at a pressure of more than 2 bar by heating with plasma generators (8). This supply of energy is sufficient to melt the stone in-situ at the face of the cavity (2), to completely or partially gasify it and to remove it from the cavity (2).

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.
