As further technological improvement, foams are placed adjacent to Ileal neobladder side in step 2 described above, as far as possible with rock
Face is closely sealed, prevents filling slurry from excessively penetrating into.
As further technological improvement, foams should have certain intensity in step 2 described above, need to be able to bear
Filling slurry bring side pressure.
As further technological improvement, foams are placed in range of the dead zone close to Ileal neobladder in step 3 described above
It is interior, to guarantee subsequent cycle compensating space in blasting.
As further technological improvement, using a circulation goaf on slush medium-length hole in step 4 described above.
The beneficial effects of the present invention are:
Foam type of the invention creates medium-length hole back production explosion collocation structure and its construction method, in big thick ore body built on the sand
After medium-length hole back production, in placing foam weakness body in subsequent cycle operation space of planes, to fill upper circulation dead zone
When, prevent obturation from enriching dead zone, there are a certain range of weak body spaces.Foams are in blasting process by comminuted broken
Bad, its volume exclusion is realized explosion compensation, completes stoping operation by the ore of avalanche.
The present invention is directed to prevent filling slurry and the close knot of pre- stope using the foams of certain volume, there are certain
The weak body space of range, when it is next be recycled back to and adopt explosion when space easily can be opened for explosion and fall mine being provided with empty profit
Between, the process for multiple cutting grooves that need to construct when big thick ore body medium-length hole back production built on the sand is changed, a large amount of explosives are saved,
It is at low cost, high-efficient, labor intensity is low, safety is good.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of foam type as described in Fig. 1-2 creates medium-length hole back production compensating space in blasting structure, including ore body 2 and filling
Body 4, the ore body 2 are equipped with drilling drift 1 and discharging tunnel 7；The drilling drift 1 is located at 2 top of ore body；The discharging tunnel
7 are located at 2 lower section of ore body；Foams 3 are equipped between the ore body 2 and obturation 4.
Barricade 5 is equipped between the discharging tunnel 7 and foams 3.
The ore body 2 is equipped with blasthole 6 close to the position of foams 3.
The foam type creates the construction method of medium-length hole back production compensating space in blasting structure, and steps are as follows:
Step 1, after the ore of upper circulation avalanche goes out sky by discharging tunnel 7, filling counterfort of constructing near open wiring mouth
5, prevent filling slurry from filling discharging tunnel 7；
Step 2 customizes foams 3 according to compensation space needed for subsequent cycle explosion；
The foams 3 of customization are sent into dead zone from rope of drilling drift 1 etc., and adjust 3 position of foams by step 3,
It is in close contact it with 2 side of ore body as far as possible；
Step 4 is filled, until obturation 4 reaches 1 floor level of drilling drift；
Step 5 after body 4 to be filled consolidates and reaches some strength, carries out long and medium hole drilling operation；
Step 6, carries out charge explosion after the completion of rock drilling operation, foams 3 in blasting process by comminuted destruction,
Its volume exclusion is realized explosion compensation by the ore of avalanche, completes back production circulation.
Foams 3 are placed adjacent to Ileal neobladder side in the step 2, closely sealed with scar as far as possible, prevent filling slurry excessive
It penetrates into.
Foams 3 should have certain intensity in the step 2, need to be able to bear filling slurry bring side pressure.
Foams 3 are placed in dead zone in the range of Ileal neobladder in the step 3, to guarantee that subsequent cycle explosion is mended
Repay space.
Using a circulation goaf on slush medium-length hole in the step 4.
The invention discloses a kind of methods that foam type creates medium-length hole back production compensating space in blasting.In thick big mine built on the sand
After 2 medium-length hole back production of body, in placing foam weakness body in subsequent cycle operation space of planes, to fill upper circulation sky
Qu Shi prevents obturation 4 from enriching dead zone, and there are a certain range of weak body spaces.Foams 3 are crushed in blasting process
Property destroy, its volume exclusion is realized explosion compensation by the ore of avalanche, completes stoping operation.
The method of the present invention mainly have the following three steps:
1. foams 3 are placed in dead zone guarantees subsequent cycle compensating space in blasting in Ileal neobladder a certain range；
2. a circulation goaf on slush medium-length hole；
3. after body 4 to be filled consolidates and reaches some strength, construction ranking hole carries out explosion, without cutting groove of constructing.
Technical requirements:
1. placing foams 3 appropriate according to the size of required compensating space in blasting；
2. foams 3 are placed adjacent to Ileal neobladder side, closely sealed with scar as far as possible, prevent filling slurry from excessively penetrating into.
3. foams 3 there should be certain intensity, it is able to bear filling slurry bring side pressure, in order to avoid be squeezed brokenly
It is bad.
The present invention is directed to prevent filling slurry and the close knot of pre- stope using the foams 3 of certain volume, there are one
The weak body space for determining range, when it is next be recycled back to and adopt explosion when space easily can be opened for explosion and fall mine being provided with empty profit
Between, the process for multiple cutting grooves that need to construct when 2 medium-length hole back production of big thick ore body built on the sand is changed, is saved a large amount of fried
Medicine, it is at low cost, high-efficient, labor intensity is low, safety is good.
