Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Example 1
Referring to fig. 1, the present embodiment provides a body to be exploded for dynamic dust suppression, which includes a body 1 to be exploded, a water bag placing area 2, and a blast hole area 3, wherein:
the body 1 of the body to be exploded comprises an upper flat disc 11 of the body to be exploded, a slope top line 12 of the body to be exploded, a side face 13 of the body to be exploded and a lower flat disc 14 of the body to be exploded;
the water bag placing area 2 is used for placing a water bag; the blast hole area 3 is provided with blast holes for blasting the body to be blasted;
the water bag placing area 2 and the hole area 3 are positioned on the upper flat disc 11 of the body to be exploded; the water bag placing area 2 and the hole area 3 are both parallel to the slope top line 12 of the body to be exploded.
Example 2
Referring to fig. 2, as an alternative embodiment, the length of the water bag placing area 2 is not less than the length of the perforation area 3. The arrangement is that the basic dust suppression effect can be achieved only by considering that the range of water mist formation is larger than the area of a blasting working area in the actual blasting operation; otherwise, if the water mist range is small, the dust formed in the blasting working area cannot be completely covered, i.e. the dust cannot be effectively removed.
Example 3
Based on example 1, with reference to fig. 3, as an alternative embodiment, the water bag is a dot matrix water bag 21. In the actual blasting operation, when the water source can not directly reach the blasting area, the operation worker is required to lift and transport, and the dot matrix water bag is selected to carry. For convenient transportation, the water content of the dot matrix water bag is preferably 30-50 kg/bag.
Example 4
With reference to fig. 4 on the basis of example 1, as an alternative embodiment, the water bag is a strip-shaped water bag 22. In the actual blasting operation, when a water source can directly reach a blasting area, the strip-shaped water bag is selected, so that water can be conveniently filled into the water bag and the next construction is facilitated. The weight of the injected water can be adaptively adjusted according to the blasting conditions.
Example 5
Based on example 3 and example 4, referring to fig. 5 and fig. 6, as an alternative embodiment, the water bag placing area 2 and the perforation area 3 are alternately arranged in sequence. When the area of the blasting area is large, a plurality of groups of water bags and blast holes need to be arranged alternately in sequence at intervals, so that a larger operation area can be covered. Meanwhile, from the consideration of the blasting effect and the water mist forming effect, the inventor repeatedly verifies that the comprehensive effect is the best when the alternating distance is 5-10 m.
Among them, examples 2 to 5 can be applied to bench blasting in an open-pit area in actual operation.
Example 6
Referring to fig. 7 and 8, as an alternative embodiment, the water bag placing region 2 and the hole region 3 are also located on the side 13 of the body to be exploded. When the body to be exploded is a high-rise building, the water bag area and the blast hole area are only arranged on the flat disc at the upper part of the body to be exploded and obviously not enough to meet the explosion requirement, so the water bag placing area 2 and the blast hole area 3 are required to be arranged on the side surface 13 of the body to be exploded at the same time.
Example 7
The present embodiment provides a blasting method, including the following steps:
(1) arranging the water bag and the blast hole on a flat disc at the upper part of the body to be exploded;
(2) adopting millisecond delay control technology to respectively control blast hole blasting and water bag blasting to enable water bags to form water mist in the height of 15 meters above a blasting area after blasting, wherein the humidity of the water mist is 90%; wherein the time lag of the water mist formation is controlled to 50ms after the blast hole blasting.
Example 8
The present embodiment provides a blasting method, including the following steps:
(1) arranging the water bag and the blast hole on a flat disc at the upper part of the body to be exploded;
(2) adopting millisecond delay control technology to respectively control blast hole blasting and water bag blasting to enable water bags to form water mist in the height of 15 meters above a blasting area after blasting, wherein the humidity of the water mist is 95%; wherein, the time for controlling the formation of the water mist is the same as the time for blasting the blast hole.
Example 9
The present embodiment provides a blasting method, including the following steps:
(1) arranging the water bag and the blast hole on the upper flat disc of the body to be exploded and the side face of the body to be exploded;
(2) adopting millisecond delay control technology to respectively control blast hole blasting and water bag blasting to enable water bags to form water mist in the height of 15 meters above a blasting area after blasting, wherein the humidity of the water mist is 90%; wherein the time lag of the water mist formation is controlled to 50ms after the blast hole blasting.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
