Water-resisting returnable multi-stage buffer fractured self-deformation self-latching shot hole stopper

Abstract

The invention belongs to the technical field of shot hole blocking in engineering blasting, and particularly relates to a water-resisting returnable multi-stage buffer fractured self-deformation self-latching shot hole stopper which solves the problems that various defects exist in existing stemming or stemming stopper, the existing stemming or stemming stopper is very undesirable in application, and the existing stemming or stemming stopper is inconsistent with the development of a modernized mine. The water-resisting returnable multi-stage buffer fractured self-deformation self-latching shot hole stopper comprises a fracturing stopper, a plurality of fracturing rings and a wedge stopper, wherein the fracturing stopper, the fracturing rings and the wedge stopper are sequentially arranged from a shot hole bottom to a shot hole opening, the fracturing stopper and the fracturing rings are sequentially in plug-in type connection, the wedge stopper is arranged behind the fracturing rings and close to the shot hole opening, and the wedge blanking stopper comprises two wedge blocks which are in matching use. The water-resisting returnable multi-stage buffer fractured self-deformation self-latching shot hole stopper disclosed by the invention has the beneficial effects of fast stopping speed, good stopping effect, safety and environment protection, no pollution, incombustibility, low cost, water resistance, quick exit performance when suffering from a blown-out shot and no secondary disaster.

Description

technical field [0001] The invention belongs to the technical field of blast hole plugging in engineering blasting, and in particular relates to a water-resistant and retreatable multi-stage cushioning and bursting self-deformation self-locking blast hole plug. Background technique [0002] Since the 1980s, the problem of blasthole filling has been paid more attention at home and abroad, and a series of studies on the mechanism of filling, filling materials, and filling length have been carried out. Studies have shown that reasonable packing can increase the explosion gas pressure in the blast hole and prolong the action time of the explosion gas pressure; promote the full reaction of the explosive to release the maximum energy and produce the least toxic gas; prevent the explosion gas from escaping freely. reduce the loss of explosion energy and explosion gas pressure, improve the thermal efficiency of explosives, and improve the working ability of explosives; prevent the e...
