Description
Technical field
The present invention relates to a kind of method for sealing, especially a kind of sealing of hole suitable for general blasting boreholes is more suitable for
The method for sealing based on swollen plasticity non-Newtonian fluid material of (super) deep hole blasting sealing of hole condition.
Background technique
Blast working at home and abroad makes in all kinds of ground and mining engineering extensively by its safe and efficient, low-cost advantage
With.In shaft production, in hard coal petrography presplitting loosening, roof weakening, top release is cut, anti-reflection, country rock is split in the increasing of hypotonic coal petrography
The fields drillhole blastings such as high stress transfer have played great function.To guarantee drillhole blasting quality and effect, it is desirable that using yellow
The materials such as mud, yellow ground or cement-roll block blasthole, and sealed borehole length is typically no less than the one third of blasthole length.Hole
On the one hand interior sealing material reduces the impact velocity that impact involves blasting broken stone, reduce the generation of punching phenomenon；On the other hand increase
The expansion work ability of detonation gas, improves explosive energy utilization rate in hole in strong hole.
Explosive payload is big in drilling, especially under the conditions of (super) deep hole blasting, it is desirable that drilling and sealing section is longer, traditional sealing of hole
The materials such as mode such as cement-roll, yellow mud powder stick are easy solidification, can meet blasthole closure quality requirement after reaching some strength, mention
High drillhole blasting efficiency.But when drillhole blasting miss-fires, handling, there is the sealing material of certain solidification intensity will have
There is great difficulty.Safety code also forbids the sealing material cured along former drilling in-situ treatment, brings to blasthole processing of miss-firing
Compared with hang-up；Under the conditions of (super) deep hole blasting, take setting parallel hole explosion treatment and miss-fire the method operability difficulty in hole
Greatly, even if it is feasible, longer parallel hole, which is accurately set, beside hole of miss-firing also is not easy.
In short, using materials such as traditional yellow mud, cement as the sealing material under the conditions of drillhole blasting, once blast hole
Appearance miss-fires and will be difficult to handle.
Summary of the invention
The present invention is directed to drillhole blasting sealing of hole problem, proposes a kind of sealing of hole side based on swollen plasticity non-Newtonian fluid material
Solid state can be presented during detonation, have using the non-newtonian fluid with shear thickening behavior as sealing material for method
Some strength guarantees sealing quality, improves explosive charge capacity usage ratio；And sealing material can be by solid-state after detonation
It is converted into liquid, there is certain fluidity, the multiplexing of convenient material and processing of miss-firing.
Method for sealing provided by the invention based on swollen plasticity non-Newtonian fluid material, using with shear thickening behavior
Swollen plasticity non-newtonian fluid is as sealing material；Sealing material is made of dispersed phase and decentralized medium；Swollen plasticity sealing material point
Dephasing component and decentralized medium generally require to be separately contained, and scene is now mixed current when using；Sealing material loads in mixture under finished condition,
Anti-corrosion should be added in finished-product material, protect the additives such as steady；
The method for sealing the following steps are included:
1) after drilling, explosive and initiating equipment are loaded；
2) to load sealing material convenient for drilling and sealing section, sealing material is packaged into column powder stick, then pushes to drilling envelope
Hole site；
3) after sealing of hole operation, on line detonation；
4) borehole initiation finishes, sealing material by it is solid state transformed be liquid, sealing material multiplexing in fairlead；When blast hole occurs
When miss-firing, equally sealing material is released, then handles the initiating equipments such as detonator or primacord, or be packed into new priming, weight
New on line sealing of hole detonation.
As an improvement, the dispersed phase of sealing material is using shear thickenings such as nano silica, cornstarch or cement bases
Agent；The decentralized medium of sealing material uses water, polyethylene glycol, polypropylene glycol or glycerol isopolarity solvent.
As an improvement, sealing material is packaged into column powder stick using soft plastic material bag, using installation in step 2
Bar pushes to sealing of hole position.
As an improvement, the dispersed phase of sealing material uses cornstarch, sealing material further includes preservative.
As an improvement, preservative uses sodium nitrite.
As an improvement, in the step 4), after borehole initiation, using with cuspidated tubule by the soft plasticity of sealing of hole
Material bag punctures, and sealing material is drawn and is multiplexed；When phenomenon occurs miss-firing in drillhole blasting, equally use the above method by sealing of hole
Material is released.
As an improvement, tubule, which uses, has antistatic, anti-corrosion function, and the flexible plastic pipe with some strength.
The beneficial effects of the present invention are as follows:
1) solid state is presented in the sealing material that the method for sealing uses in detonation process, and sealing of hole effect is good, improves drilling
Blasting efficiency, explosive energy utilization rate are high；
2) after the completion of explosion, sealing material facilitates the recycling of sealing material multiple for liquid by solid state transformed with certain fluidity
With having saved sealing material cost；
3) blast hole occurs under misfire condition, and the sealing material that liquid form is presented is easy to release, and has innovated blasthole and has miss-fired processing
Technique.
Detailed description of the invention
Fig. 1 is the packed swollen cylindric sealing of hole powder stick hole sealing structure figure of plasticity of soft plasticity；
In figure: 1- drilling, 2- explosive, 3- detonator, 4- detonator lead (primacord), the packed swollen cylindric medicine of plasticity of the soft plasticity of 5-
Volume.
Specific embodiment
By taking underground coal mine deep hole blasting as an example, carry out the deeply non-overall length powder charge drillhole blasting operation of 45m, in conjunction with attached drawing to this hair
It is bright to be further described.
As shown in Figure 1, blast hole depth is 45m, bore diameter 75mm, swollen plasticity sealing material powder stick diameter 70mm, fry
