Abstract
The invention belongs to mining blasting technical field, it is related to a kind of vertical shaft for mine explosion well completion method.The present invention ignites the pack in keyhole and is superimposed to form the light blast hole scope of freedom so as to produce down funnel structure successively, resynchronisation ignites the pack in the quick-fried layer control hole of light to form vertical shaft for mine, while demolition effect is ensured, a section dose can be reduced, reduce blasting vibration and presss from both sides stagnant effect, improve the height of shaft formatting by one blasting, construction quality and efficiency of construction.
Description
Technical field
The invention belongs to mining blasting technical field, it is related to a kind of vertical shaft for mine explosion well completion method.
Background technology
It is general to use inverse Construction method or deep hole blasting simultaneous shaft sin king construction method during traditional Construction of Silo, instead
What well construction method needed first from bottom to top construction minor diameter slips slag well, then from top to bottom expands and help into well, and quantities is big, difficulty of construction
Greatly, progress is slow, unsafe factor is more；And deep hole blasting simultaneous shaft sin king construction method, using tunneling boring Drilling deep hole and detonation is segmented,
The explosion scope of freedom is generally used as using emptying aperture, although increase into well efficiency, but explosion Free Face Conditions are poor, detonation section dose
Greatly, blasting vibration and the stagnant effect of folder are obvious, and simultaneous shaft sin king is highly small, and borehole wall shaping control difficulty is big.
The content of the invention
The purpose of the present invention is that a kind of vertical shaft for mine explosion well completion method is provided the problem of presence for prior art.
The present invention comprises the following steps：
A, setting slotting bore region and the quick-fried layer control bore region of light, the slotting bore region between drilling drift and tunnel of slagging tap
In the quick-fried layer control bore region of light, slotting bore region is vertically arranged by four and the keyhole of square arrangement is constituted,
The quick-fried layer control bore region of light is made up of the quick-fried layer control hole of multiple light being vertically arranged, and the quick-fried layer control hole of light surrounds slotting porose area
The rounded arrangement in domain；
B, carry out charging in keyhole and the quick-fried layer control hole of light, the keyhole uses section gap coupling charging, phase
Pack in adjacent keyhole is interspersed, and the quick-fried layer control hole of light, which is used, does not couple continuous charging；
C, progress explosion are first detonated successively from the bottom to top into well operations to the pack in keyhole, then in the quick-fried layer control hole of light
Pack simultaneous initiation, formed vertical shaft for mine.
The spacing of adjacent pack is 2m in the keyhole；
Clearance space in the keyhole between adjacent pack couples filling using yellow mud；
The keyhole aperture is 1.5m；
Coefficient of decoupling charge in the quick-fried layer control hole of light is 1.4-1.6.
The invention has the advantages that：
The present invention ignites the pack in keyhole and is superimposed to form the light blast hole scope of freedom so as to produce down funnel structure successively, resynchronizes
Ignite the pack in the quick-fried layer control hole of light so as to forming vertical shaft for mine, while demolition effect is ensured, can reduce a section dose,
Reduce blasting vibration and press from both sides stagnant effect, improve the height of shaft formatting by one blasting, construction quality and efficiency of construction.
Brief description of the drawings
Fig. 1 is the sectional view of hole packed plane of the present invention；
Fig. 2 is the top view of hole packed plane of the present invention.
In figure：The quick-fried layer control hole of 1- keyholes, 2- light, 3- packs, 4- vertical shaft for mine.
Embodiment
A kind of vertical shaft for mine explosion well completion method as depicted in figs. 1 and 2, it is characterised in that comprise the following steps：
A, setting slotting bore region and the quick-fried layer control bore region of light, the slotting bore region between drilling drift and tunnel of slagging tap
In the quick-fried layer control bore region of light, slotting bore region is vertically arranged by four and the keyhole 1 of square arrangement is constituted,
The quick-fried layer control bore region of light is made up of the quick-fried layer control hole 2 of multiple light being vertically arranged, and the quick-fried layer control hole 2 of light surrounds keyhole
The rounded arrangement in region；
B, carry out charging in keyhole and the quick-fried layer control hole of light, the keyhole 1 uses section gap coupling charging, phase
Pack 3 in adjacent keyhole 1 is interspersed, and the quick-fried layer control hole 2 of light, which is used, does not couple continuous charging；
C, progress explosion are first detonated successively from the bottom to top into well operations to the pack 3 in keyhole 1, then to the quick-fried layer control hole 2 of light
The interior simultaneous initiation of pack 3, forms vertical shaft for mine 4.
The spacing of adjacent pack 3 is the clearance space between adjacent pack 3 in 2m, the keyhole 1 in the keyhole 1
Coupled and clogged using yellow mud, the aperture of keyhole 1 is that the coefficient of decoupling charge in 1.5m, the quick-fried layer control hole 2 of light is
1.4-1.6。
During explosion, the pack in keyhole and the quick-fried layer control hole of light is detonated by msdelayed light emission blasting circuit, drawn
Pack in slotted eye detonates successively from the bottom to top, and Initiation time interval is 200ms, produces funnel structure and is superimposed to form light blast hole
The scope of freedom, then detonation is synchronized to the medicine in the quick-fried layer control hole of light, so as to form vertical shaft for mine 4.
