Embodiment

[0040] Example: Reference figure 1 , a detonation detonation method for detonating dust, comprising the following steps: 10. Build a plane on the top of the mountain, and draw an explosion area on the top plane 1. The explosion area is three identical isosceles triangles, and the three isosceles triangles are spliced ​​into Trapezoid, the base of the isosceles triangle in the middle is close to the mountain edge 12, the triangle in the middle is the first detonation zone 13, and the isosceles triangles on both sides are the second detonation zone 14;

[0041] 20. Drilling, opening detonation holes 11 along the vertical direction in the explosion area, and the detonation holes 11 are evenly distributed in the explosion area;

[0042] 30. Embed a detonator in the detonation hole 11;

[0043] 31. A dust suppression device 2 for sprinkling water and dust reduction is placed in front of the second detonation zone 14;

[0044] 40. Detonation. First, the first detonation zone 13 d...

Abstract

The invention discloses a delayed detonation method for blasting and dust reduction, which is applied in the field of mountain blasting and dust reduction, and solves the technical problem of a huge amount of dust in the process of mountain blasting. The explosion area, the explosion area is three identical isosceles triangles, and the three isosceles triangles are spliced ​​into a trapezoid at the same time. The waist triangle is the second detonation area. First, the first detonation area detonates first, and the second detonation area detonates later. The detonators in the first detonation area are detonated from the edge of the mountain to the inner side one by one. The zone is detonated row by row in the direction away from the first detonation zone; the technical effect is to reduce the height of the collapse and the energy generated during the explosion, thereby reducing the amount of dust outbreak.

Description

technical field [0001] The invention relates to the field of mountain blasting and dust suppression, and more specifically, it relates to a delayed detonation method for blasting and dust suppression. Background technique [0002] Blasting is to use the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock medium or objects. When the explosive package or charge explodes in the soil-rock medium or structure, the soil-rock medium or structure will be compressed, deformed, destroyed, loosened and thrown, and it is mainly used in earth-rock engineering. [0003] Currently, if Figure 6 As shown, a method of delayed detonation of blasting, firstly drill rows of detonation holes 11 downward along the direction perpendicular to the mountain top plane 1, and embed detonators in the detonation holes 11, starting from the edge 12 of the mountain body, the same horizontal row The detonators of the detonators detonate at the same ...
