Explosion, intermetallic composite coating etc. are also widely used for the science and technology fields such as seismic prospecting, in explosive analysis field, due to the modern times point
The fast development of analysis technology, range, precision and the analysis efficiency of detection have the raising of matter, but sample technology of preparing is special
It is not that wherein organic component separation and extraction technology stagnates always, becomes the bottleneck for restricting analytic process, with national economy
Rapid development, New Explosives product composition is increasingly sophisticated.
Photoface exploision abbreviation light is quick-fried, is a kind of reasonable Controlled blasting technique using explosive energy, since explosive explodes
The detonation pressure of middle generation is considerably beyond the compressive ultimate strength of any rock, and the rock of powder stick attachment will under normal circumstances
The crushing fried is compressed to a cavity, but if selecting suitable explosive, is aided with rational charge constitution, can control
Impact the comminuted destruction of dynamic pressure.
The rock breaking mechanism of photoface exploision is a sufficiently complex problem, still among exploration, although in theory also not
It is very ripe, but the existing common recognition in terms of qualitative analysis, it is considered that, when explosive initiation, three kinds of effects are generated to rock mass:First, answering
Reeb reflected tensile destroys role;Second is that explosion gas expansion work role;Third, the two collective effect institute
The destruction risen;Research, experiment and production practices in recent decades show that the third Benefit Transfer meets engineering practice;
Photoface exploision is periphery hole while detonating that its surrounding of the impact wave direction of each borehole makees radial propagation, and the impact of adjacent borehole is met,
The superposition of stress wave is then generated, and generates tangential pulling force, the maximum value of pulling force is happened at the midpoint of the adjacent borehole line of centres, when
When the ultimate tensile strength of rock mass is less than this pulling force, rock mass just by drawing crack, forms crack on the borehole line of centres, then, quick-fried
The expansion of fried product makes crack further expand, and forms smooth surface of rupture, to obtain good photoface exploision as a result, its
The explosive of selection and the blasting method of use be also it is very crucial, therefore, research and develop a kind of smooth blasting method make it is quick-fried in smooth surface
The operation effectiveness for reaching best in broken becomes those skilled in the art's technical problem urgently to be resolved hurrily.

Experimental example 1
To the method progress explosion measurement for the photoface exploision that embodiment 1, embodiment 2 and embodiment 3 provide, the knot of measurement
Fruit such as table 1.
1. test result of table
According to the data of table 1 it is found that the embodiments of the present invention also provide tunnel photoface exploision method, be used for tunnel
Explosion mainly uses the compound filling shot hole blasting of water-soil, and explosive explodes in blasthole to be had the property that:(1) high pressure air mass
Expansion forms high-speed jet, can play the role of reinforcing catalase.(2) when shock wave passes through aqueous medium, due to the compression of water
Property is small, and compared with other media, the explosion energy of absorption is few.Therefore compared with common photoface exploision, there is energy-saving effect.(3)
The energy transfer efficiency of aqueous medium is high and uniform, therefore explosive consumption is small, and breaking size is uniform.(4) blasting dust can be by aqueous vapor
It absorbs, plays the role of atomized dust settling.Therefore, the compound filling blasthole of water-soil replace pure stemming clog blasthole, using water can not
The wad act of compressibility and stemming reduces decaying of the shock wave in communication process, the opposite effect for extending detonation gas
Time improves the degree of fragmentation of rock and the effective energy utilization rate of explosive, save explosive, accelerate drilling depth, improve through
Ji benefit, while also improving construction environment in tunnel.
