Problems solved by technology

[0004] The traditional blasting dust reduction method in open-pit mines is to reduce blasting dust by sprinkling water on the surface of the blasting area before blasting. This can only reduce the amount of dust generated on the surface, but when blasting, the blasting body moves towards the air surface, and the air surface and blast holes will be damaged. generate a lot of dust

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] The invention provides a blasting dust suppression method, comprising the following steps:

[0026] (1) Before the blasting is carried out, the device containing the water-absorbing material 4 is covered and installed on the site to be blasted;

[0027] (2) After the installation is completed, water is sprinkled on the water-absorbing material of the device to soak the water-absorbing material, and then blasting is carried out.

[0028] Specifically, the ...

Abstract

The invention provides a blasting dust-falling blasting quilt method. The method comprises the following steps that (1) before blasting, and a device containing a water absorption functional material is mounted on a blasted site in a covering mode; and (2) after mounting is completed, water is sprayed to the water absorption functional material of the device to soak the water absorption material, and then blasting is carried out. According to the blasting dust-falling blasting quilt method, the effects of flying stone prevention and dust prevention are achieved at the same time in the blasting process, the device is simple in structure and capable of being repeatedly used, the dust falling effect is extremely good, and environmental pollution and harm to constructors are effectively reduced.

Description

technical field [0001] The invention relates to the fields of engineering blasting technology and environmental protection technology, in particular to a blasting dust suppression method. Background technique [0002] The scale of open-pit mines is huge, which will have a great impact on the surrounding environment in actual production, among which dust pollution is the most obvious. Especially in open-pit blasting operations, a large amount of dust will be generated. Due to the unique pit structure of open-pit mines, the dust in the pit is difficult to spread, especially the small particles of dust suspended in the air can be inhaled by the human body and cause pneumoconiosis. Dust pollution has greatly restricted the green and efficient mining of mines. [0003] Blasting technology has been widely used in engineering construction. With the rapid development of engineering, engineering construction is more and more dependent on blasting technology, and the application rang...
