Embodiment Construction

[0015] Embodiments of the present invention: a blasting method of a high-efficiency blasting device, the method forms blasting main blastholes and auxiliary blastholes respectively by drilling holes, the auxiliary blastholes are arranged around the blasting main blastholes, and put Sufficient explosives, blasting devices are placed in the auxiliary blast holes, and the differential blasting technology is used to make the main blast hole first explode on the surrounding rock mass, which can produce a blasting effect on the deep rock mass, that is, rock mass loosening, cracks and stress fields Then the auxiliary blastholes around the main blasthole are detonated sequentially, and the secondary blasting main body of the blasting device in the auxiliary blasthole can be advanced axially into the deep rock body to complete the blasting work.

[0016] The depth of the main blasthole is greater than the depth of the auxiliary blasthole. Generally, the depth of the main blasthole can b...

Abstract

The invention discloses a blasting structure of an efficient blasting device. The blasting structure of the efficient blasting device comprises a geological part needing to be exploded, wherein a mainblast hole is formed in the geological part needing to be exploded, an auxiliary blast hole is formed in the periphery of the main blast hole in sequence, an explosive is placed in the main blast hole, a blasting device is arranged in the auxiliary blast hole, and the main blast hole and the auxiliary blast hole are connected in sequence through a detonation line. According to the blasting structure of the efficient blasting device, the method is mainly designed by utilizing a micro-differential blasting technology, a bottom-bottom blasting technology and a water interval blasting technology,the explosion vibration is reduced, the large block amount is reduced, the single-consumption amount and the dust concentration of the explosive are reduced, the utilization rate of a blast hole is increased, the blasting effect is increased, and the explosion safety is improved.

Description

technical field [0001] The invention relates to the field of blasting technology, especially a blasting structure of a high-efficiency blasting device. The filing date of the application is: 2017.01.13, the application number is: 201710026415X, and the name of the invention is: a blasting method and structure of a high-efficiency blasting device Divisional application. Background technique [0002] At present, in the process of tunnel construction in my country, mechanized excavation has not been used on a large scale and has not reached the developed level. Blasting technology, especially drilling and blasting, is the main method of tunnel construction in my country, but the utilization rate of blast holes in tunnel excavation is low, and the blasting effect is low. It is not obvious that the low efficiency and slowness of the excavation depth is the main difficulty, and the construction is very difficult. [0003] In the process of coal mining in my country, especially in ...
