Description
Technical field
The present invention relates to blast working field, especially a kind of aqueous blast hole mortar isolating device and use isolation dress
The method for putting isolation bulk explosive and mortar.
Background technology
At present, the bulk explosive such as on-site mixed emulsion because of its filling efficiently, the advantages that safe and reliable, cost is cheap,
It is used widely in blast working.But in blast working operation, due to the infiltration of blast hole bottom, drill residual water etc.
Reason, the situation of blast hole ponding is relatively common, and this part ponding and the rock slag of drilling rock drilling form mortar in blast hole bottom
Shape mixture.When injecting bulk explosive to blast hole, due to pumping pressure and explosive Gravitative Loads, blast hole bottom has one
Part explosive mixes with mortar, is mixed into the bulk explosive of the impurity such as mortar, and brisance, which reduces, even loses explosion property, causes
Dose wastes, and occurs remaining bottom bank, influences demolition effect, increases post-processing cost.
China Patent Publication No. is that the U of CN 201672887 utility model patent discloses a kind of deep hole blasting water hole use
Bottom hole dregs of a decoction isolator, it is the bottom hole dregs of a decoction isolator of irony disc shape, isolation blast hole base charge and mortar can be played
Effect.However, in blast working practice, there is larger defect in above-mentioned isolator：
1st, the mortar proportion that blast hole bottom is mixed to form by water and rock slag is larger, has stronger damping characteristic, disc
The deflection that shape dregs of a decoction isolator relies solely on self gravitation can not cause to lose buffer action in bottom hole automatic turning sometimes.
2nd, to realize sinking bottom, disc shape dregs of a decoction isolator diameter must be smaller than explosion aperture, causes screed can be from
Isolator and hole wall gap overflow, isolation effect are bad.
Existing other isolation technologies are similar with disc shape dregs of a decoction isolator, isolated using the heterotypic material of certain form
Bulk explosive and mortar in blast hole, generally existing isolator enter hole operation inconvenience, it is impossible to adapt to the change of the screed depth, isolation
It is ineffective, take the defects of hole depth reduces blast hole utilization rate.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of aqueous blast hole mortar isolating device and its partition method,
Can solution must not adapt to the screed depth change, isolation effect is bad, take hole depth reduce blast hole utilization rate the problem of, have
Explosive layer and screed in effect isolation blast hole, avoid the explosive of blast hole bottom from mixing and fail with mortar, improve explosive profit
With rate, avoid remaining rock bank, save blasting cost.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of aqueous blast hole mortar isolation dress
Put, the device includes batching sphere hollow made of flexible plastic film, and slip casting flexible pipe is communicated with the spheroid of batching sphere, isolation
Bulk explosive has been filled in the spheroid of ball, has filled the 90-95% in a diameter of blast hole aperture of the spheroid of bulk explosive.
Thickness >=0.3 millimeter of flexible plastic film.
This method comprises the following steps：
1）Measure the depth h of screed in blast hole；
2）According to the diameter of phi of blast hole and hole depth H, with reference to step 1）The depth h of the screed of measurement, calculate needed for every
From the diameter and quantity of ball；
3）Make batching sphere：Into hollow spheroid inject bulk explosive to filling, fill bulk explosive spheroid it is straight
Footpath is step 2）Calculated value, spheroid fills rear enclosed slip casting flexible pipe, that is, batching sphere is made；
4）It is put into blast hole no less than step 2）The batching sphere of the quantity calculated, batching sphere sink in Gravitative Loads
Separation layer is formed in screed；
5）Bulk explosive is injected into blast hole and forms explosive layer in hole, in pumping pressure and batching sphere self gravitation effect
Under, batching sphere is pressurized is deformed into round pie by spheroidal, and the diameter in aperture direction becomes big, and ball wall is brought into close contact with hole wall；
Realize isolating for bulk explosive and mortar in aqueous blast hole.
Step 1）The depth h measuring method of screed be：With in long waddy or bamboo cane insertion blast hole until bottom hole,
Long waddy or bamboo cane are transferred to, the depth h of screed can be measured according to the mortar trace remained thereon.
Step 3）In, close slip casting flexible pipe using knotting or heating the firm method of closure by slip casting flexible pipe.
Step 4）In, in batching sphere sinking watching, if meeting blast hole local deformation jam occurs, it will be isolated using waddy
Ball is gently disclosed into bottom hole.
A kind of aqueous blast hole mortar isolating device and its partition method provided by the invention, have the beneficial effect that：
1st, isolating device is to use batching sphere hollow made of flexible plastic film, fills bulk explosive, is put into explosion
In hole, under pumping pressure and bulk explosive Action of Gravity Field, batching sphere is pressurized is deformed into round pie by spheroidal, along aperture direction
Diameter become big, ball wall is brought into close contact with hole wall, is effectively isolated explosive layer and screed in blast hole, is avoided blast hole bottom
Explosive is mixed and failed with mortar, improves explosive utilization rate, is avoided remaining rock bank, is saved blasting cost.
2nd, the non-directional requirement in blast hole of batching sphere made of flexible plastic film, enters when hole is sunk to the bottom and is not easy by blast hole
Local deformation defective effect, strong adaptability, it is simple to enter hole operation.
3rd, one or more batching spheres are put into according to the dynamic adjustment of mortar layer depth and form separation layer, make the height of separation layer
All the time mortar layer depth is exceeded, can flexible adaptation blast hole screed change in depth, it is ensured that isolation effect.
4th, the explosive layer that the bulk explosive of injection participates in being injected into blast hole in batching sphere explodes acting jointly, blast hole
Utilization rate is higher, and controlled blasting is more accurate.
5th, isolating device makes simple, and easy to use, cost is cheap, applied widely, to have water have slag, it is anhydrous have slag or
Anhydrous no slag blast hole is applicable.
