    摘要： The present invention relates to a method in the excavation of rock caverns, substantially cylindrical vertical caverns, for storing liquids or dry products, or for use in storing process units, in which method an upper and a lower circumferentially extending cavern (4, 11) is formed, the caverns (4, 11) having an outer diameter which is greater than the diameter of the ultimate rock cavern (1); in which the caverns (4, 11) are connected together by means of vertical holes (12) drilled in the region immediately outside the ultimate rock cavern (1), these vertical holes (12) serving to drain water from the aforementioned region, for the purpose of minimizing the extent to which water can penetrate the rock cavern (1). (FIG. 1).

    摘要： A method for filling an elongated sump which has a plurality of diverter gates emptying into the sump is accomplished by dividing the sump into a plurality of adjacent zones along each side of the sump and adding slurry in each of the zones in sequential order in a direction related to the direction of movement of a dredge removing material from the sump. The sequencing automatically skips the zone where the dredge is removing material and empties it during that period of time in the sequence just previously emptied.

    摘要： A NOVEL OPEN GUTTER OR DRAIN FOR DIVERTING LIUQIDS IS DISCLOSED, SAID GUTTER BEING CHARACTERIZED BY THE PROVISION OF A FOIL STRIP WHICH IS REGIDLY CONNECTED WITH AT LEAST ONE REINFORCING ELEMENT. THE FOIL STRIP IS DEFORMED ABOUT ITS LONGITUDINAL AXIS THUS BENDING THE REINFORCING ELEMENT, THE CROSS-SECTION OF THE GUTTER SO FORMED BEING ARCUATE IN SHAPE. THE NOVEL OPEN GUTTER IS SUCH THAT IT CAN EASILY BE DISPLACED IN ALL DIRECTIONS WITHOUT EFFECTING A CHANGE IN ITS CROSS-SECTIONAL CONFIGURATION.

    摘要： A method for constructing a dam inside a dump of an inner-dump strip mine includes: taking an upper surface connection line of a primary water-resisting layer as upper filling reference datum boundary of an artificial water-resisting layer; arranging a dam foundation pit and a trapezoidal abutment on a midline of the dam foundation pit; building and reinforcing a step-shaped retaining dam core wall on the artificial water-resisting layer; laying a foundation impervious layer, waterproof geotextile, and an earth blanket on one side, close to the primary aquifer, of the retaining dam core wall; strengthening advance of a dumping working face on one side, away from the primary aquifer, of the retaining dam core wall, and dumping overburden of a strip mine to form a support; filling a space between the earth blanket and the primary aquifer to form a blocker; and proceeding with construction and forming a continuous retaining dam.

    摘要： A system for forming a cavity in a backfill mixture comprising granular material and water positioned in an at least partially excavated stope. The system includes a base and a drainage tube assembly in an extended condition thereof. The drainage tube assembly extends between a lower end secured to the base and an upper end positioned above an upper surface of the backfill mixture. The extended drainage tube assembly includes a tube portion thereof with a permeable material and defining the cavity therein into which the water from the backfill mixture is drainable, through the permeable material. The system also includes a drainage pipe, for permitting the water that has drained into the cavity of the extended drainage tube assembly to exit the stope.
