As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 2, a energy concentrating structure comprises an energy concentrating cover 52 and an energy concentrating sleeve 51, wherein the energy concentrating cover 52 is a hollow cone structure, one side of the energy concentrating cover is provided with a conical groove, the energy concentrating cover 52 is positioned on one side of the energy concentrating sleeve 51, the conical groove faces to the outer side of the energy concentrating cover 52, the energy concentrating cover 52 is made of metal, and the vertex angle of the energy concentrating cover 52 is 30-150 degrees.
By arranging the energy-gathering cover 52, the energy-gathering cover 52 of the energy-gathering structure 5 is arranged at the end part of the energy-gathering pipe 7 or the explosive, and energy-gathering jet flow is formed when the explosive or the energy-gathering pipe 7 explodes, so that stable and long-distance explosion transfer can be realized.
At this time, the energy-gathering cover 52 is set to be a hollow cone structure with a cone angle, after explosion, the energy-gathering cover 52 forms energy-gathering jet flow, so as to realize stable long-distance explosion propagation, and in order to form energy-gathering jet flow, the angle of the top angle of the energy-gathering cover 52 is 90 ° -120 ° (angle a in fig. 1), specifically, in this embodiment, the angle of the top angle of the energy-gathering cover 52 is 90 °. Meanwhile, the wall thickness of the energy-gathering cover 52 is 0.5mm-2mm (d in fig. 1), in the embodiment, the thickness of the energy-gathering cover 52 is 1mm, and too thin or too thick of the energy-gathering cover can cause that the formed energy-gathering jet flow cannot detonate the next explosive, so that stable remote explosion transfer cannot be realized. At this time, for the wall thickness of the shaped cap 52, the wall thickness of the shaped cap 52 may be all set to be the same, or different wall thicknesses may be set at different positions, for example, the thickness of the hollow cone gradually increases from the top to the bottom, but of course, other forms of thickness variation are also possible.
In order to form the energy-gathered jet flow during explosion, the energy-gathered cover 52 is made of metal, the temperature is high during the explosion process, and in order to prevent the energy-gathered cover 52 from being gasified, in the embodiment, the energy-gathered cover 52 is made of copper, aluminum, iron, a copper alloy, an aluminum alloy or an iron alloy, specifically, at this time, aluminum is used as the material of the energy-gathered cover 52, at this time, the energy-gathered cover 52 has certain ductility and is not easy to be gasified, when the energy-gathered cover is fixed at the end of the explosive or the energy-gathered pipe 7 filled with the explosive, the energy-gathered jet flow can be formed, so that the explosive on the side surface of the energy-gathered cover is detonated, stable long-distance explosion transfer is realized, at this time, the explosion transfer distance can reach 30cm-100cm, therefore, under the condition of spaced charging, the explosion transfer can be realized without increasing an explosion guide rope, and stable long-distance explosion transfer is realized, and the cost is saved.
The energy gathering structure 5 needs to be fixed at one end of the explosive or the energy gathering pipe 7, at this time, the energy gathering sleeve 51 is mainly used for connection, so the energy gathering cover 52 and the energy gathering sleeve 51 can be integrated or separated according to actual requirements, in the embodiment, the energy gathering cover 52 and the energy gathering sleeve 51 are separated, and since the energy gathering cover 52 needs to be made of metal (aluminum is adopted in the embodiment), in order to reduce production cost, the energy gathering cover 52 and the energy gathering sleeve 51 are separated, the energy gathering sleeve 51 is made of plastic materials, and the two are produced separately and then assembled together.
When the energy-gathering cover 52 and the energy-gathering sleeve 51 adopt a split structure, an annular boss is arranged on the outer side of the bottom of the energy-gathering cover 52, a limiting part is arranged at the bottom of a cone structure of the energy-gathering cover 52, and the limiting part is abutted against the annular boss so that the energy-gathering cover 52 and the energy-gathering sleeve can be assembled together and then fixed at the end part of an explosive or an energy-gathering pipe.
A spaced-charge energy-gathered blasting method is disclosed, as shown in figure 3, and comprises the steps of installing energy-gathered structures 5 at the end parts of explosives or energy-gathered pipes 7 filled with the explosives, arranging the explosives or the energy-gathered pipes 7 filled with the explosives in a blast hole 1 in sequence in a spaced mode, connecting at least one explosive or energy-gathered pipe 7 filled with the explosives with a blasting device, and enabling conical grooves of energy-gathered covers 52 of the energy-gathered structures 5 to face the same direction as the detonation propagation direction of the explosives or the energy-gathered pipes 7 filled with the explosives.

After the energy concentrating cover 52 is adopted, the distance between the explosive or the energy concentrating pipes 7 filled with the explosive is 30cm-100cm in the embodiment, because stable long-distance explosion propagation can be realized. The spacing between the explosive charges or the energy collecting pipes 7 can be set according to actual requirements.

The gas column bag 6 is low in overall cost, does not need to be inflated when not in use, occupies a small space, can be inflated manually or by adopting an air gun when in use, is simple and convenient, and can be combined randomly by setting the gas column bag 6 to be different specifications of length, such as 30cm, 40cm, 50cm and the like, so that the distance between adjacent explosives or energy collecting pipes 7 can be controlled. In the use process, the gas column bags 6 with the corresponding sizes after being inflated are placed into the blast hole 1, namely, an interval can be formed between the adjacent explosives or the energy-gathering pipes 7, and when the explosives explode, the overall influence of the adopted gas column bags 6 on the explosion can be ignored.
