Embodiment Construction
[0021] In order to further describe the present invention, a blasting method of the present invention that effectively reduces the hazards of gun smoke will be further described below in conjunction with the accompanying drawings and examples.
[0022] Depend on figure 1 Shown is a schematic diagram of the charge structure used in a blasting method that effectively reduces the hazards of gun smoke and is combined with figure 2 , image 3 It can be seen that a kind of blasting method that effectively reduces the harm of blast smoke of the present invention is implemented according to the following technological process:
[0023] 1) When charging each blast hole, according to the designed amount of charge, firstly load explosive 1 at the bottom of the blast hole, and load detonator 2 at the same time as explosive 1 is loaded, and detonator 2 is drawn out through detonator foot line 3 orifice;
[0024] 2) In the upper blasthole of the explosive 1 loaded at the bottom of the b...

The invention discloses a blasting method capable of effectively reducing fume harm. When each blasting hole is charged, the bottom of each blasting hole is charged with explosive (1), and meanwhile, a blasting cap (2) is loaded, and then the upper part of the explosive (1) is provided with an interval column (5) filled with water, the explosive (1) and the interval column (5) are successively and circularly loaded until the explosive height meets the design requirement; at the end, plugging stemming (7) is loaded into the blasting holes, and after all of the blasting holes are loaded, detonator wires of all of the blasting holes are networked to be detonated. When the explosive is exploded, water is participated in the chemical reaction of the explosion, so that carbon monoxide, oxynitrides or other poisonous and harmful gases generated by the explosion are combined with water to form a new compound, the fume can be reduced, and the fume harm is reduced. The operation is simple and safe, and the blasting method is particularly suitable for all underground blasting operations, and open-air blasting operations.
Description
technical field [0001] The invention belongs to the technical field of blasting, in particular it relates to a method capable of effectively reducing the generation of toxic and harmful gas (namely gun smoke) during blasting, which is suitable for various types of blasting such as modern industrial mine production, stone mining, urban and traffic construction control blasting, etc. It is used in blasting and is especially suitable for tunneling and blasting. Background technique [0002] The dust and gun smoke produced by blasting have caused great harm to the human body and the environment, so the control of blasting hazards has always been an important topic in the field of engineering blasting. [0003] At present, a large amount of gun smoke will be generated during mining in industrial and mining enterprises and blasting of open-air step stripping. When underground mines are blasted, the explosion of explosives is easy to generate gas containing a large amount of poiso...
