Abstract
The invention discloses a spiral energy-gathering type slotting explosive column casing. The spiral energy-gathering type slotting explosive column casing comprises a capping cover, an explosive body and a sealing bottom cover, and is mainly used for slotting explosion. A triangular spiral groove is formed in the cylindrical explosive column, when the explosive column is exploded, rocks, in the triangular spiral groove, on the explosive column form fissure surfaces in the groove region under the action of energy-gathering detonation metal flow, the length of rock cracks can be further increased under the action of subsequent blast hole explosion for crushing rocks within a groove cavity range and throwing the rocks out of the groove cavity, so that the slotting explosion effect can be improved; moreover, the two sections of the explosive columns can be quickly connected through the tower-type design of the top and the tail, so that the explosives can be saved more in comparison with the conventional explosive column with the same length and diameter.
Description
Technical field
The present invention relates to a kind of powder column housing, particularly relate to a kind of spiral energy collecting type slotting powder column housing.
Background technology
Unfavorable factor in Cut Blasting has 2: one to be that the scope of freedom is single, and rock is volumetric expansion in shattering process, and single degree of freedom face cannot provide sufficient expansion space to be the main cause causing slotting effect poor; Two is clamping actions of rock mass, and along with mining depth increases, the clamping action in Cut Blasting between rock block significantly increases, and this is another unfavorable factor of Cut Blasting.At present, a series of research work has been carried out in order to realize stone head speedy drivage, this improves cyclic advance to a certain extent, but to the unfavorable factor how overcome in Cut Blasting, the research improving blast hole utilizing factor is still not deep enough, in explosion powder column, just need badly and develop a kind of saving explosive, the slotting powder column that slotting is effective.
Summary of the invention
In order to overcome the unfavorable factors such as the single and rock clamping action in the scope of freedom in current Cut Blasting, the invention provides a kind of spiral energy collecting type slotting powder column housing.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of spiral energy collecting type slotting powder column housing, comprises top pressure closure (1), powder column body (2), sealing bottom (3) three major parts, below said " up and down " refer to the position relationship in Figure of description;
Described top pressure closure (1) is concave plastic closure, inner lid has two tower grooves, outer wall has two tower projections, and bottom is hemispherical, directly covers on powder column body (2) top;
Described powder column body (2) is the cylindrical cavity body of rod, for PVC material, the body of rod is distributed with the spiral groove of triangle (4), channel section shape is triangle, body of rod diameter containing the spiral groove of triangle is less than not containing the diameter of groove, powder column body (2) upper end inwall there are two tower grooves, top pressure closure (1) is convenient to be connected to powder column body (2) upper end, in addition, two circular ports (5) are diametrically had on powder column body (2) top, bottom inwall is internal thread, sealing bottom (3) is convenient to be connected to powder column body (2) bottom,
Be provided with metal energy gathering cap (6) housing of same shape in described spiral groove (4), be close on spiral groove (4) wall;
Described sealing bottom (3), outer wall has two tower projections, and bottom is hemispherical, and sealing bottom (3) top is external screw thread, and sealing bottom (3) is connected by screw thread with between powder column body (2);
Operation principle:
The present invention arranges the spiral groove of triangle on traditional cylindrical powder column, the metal energy gathering cap of same shape is pasted above groove, according to the principle of jet perforating, powder column explosion time, when detonation wave arrives metal cumulative cover, metal cap is owing to being subject to strong compression, inner surface portion metal is out squeezed, along the spiral groove of triangle outside jet at a high speed, energy is also the most concentrated, there is stronger directed width generation capacity, fissure-plane is formed in the spiral recess region of triangle, under follow-up big gun hole detonation, the length of rock crackle forming can be increased further, by rock crushing within the scope of vallecular cavity, and throwing goes out vallecular cavity.
Compared with prior art, advantage of the present invention is:
The present invention arranges the spiral groove of triangle on cylindrical grain, and this compares with equal length can save explosive with the powder column of diameter, also can significantly improve the rock breaking capacity of powder column; The present invention is according to the explosion thought of " first cut and draw afterwards ", powder column explosion time, on powder column, the rock of the spiral groove of triangle produces many crackles under the effect of cumulative detonation metal flow, and form fissure-plane in the spiral recess region of triangle, then under follow-up big gun hole detonation, detonation wave can strengthen the fragmentation of keyhole surrounding rock, by rock crushing within the scope of vallecular cavity, and throwing goes out vallecular cavity, this can improve Cut Blasting effect, and improves cyclic advance to a certain extent.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
A kind of spiral energy collecting type slotting powder column housing, comprises top pressure closure (1), powder column body (2), sealing bottom (3) three major parts, below said " up and down " refer to the position relationship in Figure of description;
Described top pressure closure (1) is concave plastic closure, inner lid has two tower grooves, outer wall has two tower projections, and bottom is hemispherical, directly covers on powder column body (2) top;
Described powder column body (2) is the cylindrical cavity body of rod, for PVC material, the body of rod is distributed with the spiral groove of triangle (4), channel section shape is triangle, body of rod diameter containing the spiral groove of triangle is less than not containing the diameter of groove, powder column body (2) upper end inwall there are two tower grooves, top pressure closure (1) is convenient to be connected to powder column body (2) upper end, in addition, two circular ports (5) are diametrically had on powder column body (2) top, bottom inwall is internal thread, sealing bottom (3) is convenient to be connected to powder column body (2) bottom,
