Definitions

  • the invention relates to a method for sinking and sealing a blast hole for seismic exploration of a ground formation, in which the blast hole is drilled in the direct flushing drilling method and filled with a sealing material.
  • Drilling fluids with polymeric additives are used to stabilize the borehole and to discharge the drilling material. Nevertheless, depending on the stability of the drilled layers, falling and washing up can lead to borehole widening of up to 70%, based on the diameter of the drill bit.
  • an explosive cartridge is placed on the bottom of the borehole through the borehole still in the borehole. adorned and then filled the hole after pulling the rod.
  • cardboard sleeves filled with bentonite are said to swell up to the existing borehole diameter and to seal the bore mechanically and hydraulically.
  • the invention is based on the object of specifying a method of the type mentioned at the beginning which improves the sinking and closing of blasting holes with regard to the requirements mentioned at the outset.
  • this object is achieved in that a slowly hydraulically hardening suspension of water and a fine-grained mixture of clay minerals and hydraulic binder is used as the drilling fluid and that the blasting hole is filled with the suspension after its completion and the use of the explosive charge, and then the The suspension in the blast hole sets into a tight and firm stopper.
  • the method according to the invention is characterized by a number of advantages which considerably simplify and reduce the cost of producing explosive bores.
  • the use of a suspension suitable as drilling fluid and backfill material considerably reduces the material requirement and the workload, especially for filling the blast holes, is significantly reduced.
  • the production of the suspension is comparable to the production of suitable drilling fluids and therefore requires no additional effort. There is no need to use expensive rinses and chemicals.
  • the suspension provides support for the borehole and, by penetrating the suspension into the boundary layer of the soil adjacent to the borehole, a filter cake is formed which prevents the suspension mass from flowing out of the borehole.
  • the suspension After loading the blast hole and pulling the drill pipe, the suspension completely fills the borehole, so that hardening of the suspension, preferably in a period of 48 hours, forms a solid, dense body which closes the borehole securely and seals the drilled soil layers against each other in the required manner.
  • the work required to fill the borehole since then has been eliminated. Only the displacement volume of the drill pipe can be compensated for by refilling the suspension. Because of its flowability, the suspension completely fills the borehole and thereby avoids disadvantages of incomplete filling, as can result from the known methods.
  • the suspension is adjusted so that the pressure resistance of the stopper reaches 0.4-0.8 N / mm 2 after setting.
  • the permeability of the erhärte ⁇ th suspension should be according to the invention at least 10 "8 m / s.
  • the density of the suspension should preferably be approximately 1.2 kg / 1 in order to obtain a favorable flushing behavior when sinking the bore.
  • the suspension contains bentonite activated as clay mineral. The properties of the bentonite mean that the plug can be adequately stable and sealed with a comparatively low cost of material.
  • the mixture of clay minerals and binding agent can be dispersed in the water to produce the suspension with the aid of the drilling pump's flushing pump. Additional devices or facilities are therefore not required.
  • the explosive charge in the borehole is covered with a bed of gravel or drillings. As a result, an additional securing of the explosive charge is achieved, especially in the case of shallow explosive bores.
  • a fine-grained mixture of activated bentonite and hydraulic binder, preferably cement is poured into a water reservoir of 400-100 kg and poured in for 6 minutes using the Piston pump of the drilling rig dispersed.
  • the result is a stable suspension with a density of 1.2 kg / 1, which is used as drilling fluid when sinking the borehole and, in addition to stabilizing the borehole, also serves to discharge the cuttings.

Abstract

Selon un procédé de creusage et d'étanchement de trous de mines d'exploration sismique d'une formation géologique, le trou de mine est creusé par un procédé direct de forage avec injection d'eau et est rempli d'un matériau d'étanchéité. On utilise comme liquide de forage une suspension hydraulique à durcissement lent constituée d'eau et d'un mélange finement granulé de minéraux argileux et d'un liant hydraulique. Quand le trou de mine est achevé et la charge explosive y est introduite, le trou de mine est rempli de la suspension preparée de manière à durcir dans les 48 heures à l'intérieur du trou de forage pour former un bouchon étanche et solide.
