FIELD: drilling of soil or rocks; explosion works.
SUBSTANCE: invention relates to drilling and blasting operations. Method of the composite hardening tamping 28 installing in the groove 1 cavity 2 in the form of a blast-hole or a well during drilling and blasting operations is as follows. Composite hardening tamping 28 is placed in contact with the surface of the thrust means fixed along the tamping 28 longitudinal axis. Thereafter, exerting the external axial dynamic action on the tamping 28 from the groove 1 mouth 17 side, with the possibility of the composition structure changing, in particular mixing its components or structural compaction. By this enabling the composition hardening in the zone of the tamping 28 technologically regulated arrangement in the groove 1 cavity 2. As the thrust means fixed along the groove 1 axis with surface in contact with the said tamping 28 a technological structure is used, which is structurally performed with the possibility of its placement in the groove 1 cavity 2 at a distance set from the groove 1 mouth 17. For this, a stop-measuring element, means 19, rigidly connected to the technological structure is used, with its positioning means in the groove 1 cavity 2 relative to the mouth 17 of the later and subsequent fixation of this thrust means relative to the fixed basic structure, for example, the rock surface section 21 adjacent to the groove 1 mouth 17 in place of the thrust means specified installation in the groove 1 cavity 2. Provided are design options of the thrust means implementation.
EFFECT: invention allows to provide a fixation ensuring complete exclusion of interaction with the explosive substance.
