Description
Technical field
The present invention relates to blast working field, especially a kind of aqueous blast hole mortar isolating device and the method that bulk explosive and mortar are isolated using this isolating device.
Background technology
At present, the bulk explosive such as on-site mixed emulsion because its filling efficient, safe and reliable, with low cost the advantages of, be used widely in blast working.But, in blast working operation, due to reasons such as the infiltration of blast hole bottom, boring back water, the situation of blast hole hydrops is relatively common, and this part hydrops forms sand paste mixture with the rock slag of boring rock drilling in blast hole bottom.When to blast hole injection bulk explosive, due to pumping pressure and explosive Gravitative Loads, blast hole bottom is understood some explosive and is mixed with mortar, it is mixed into the bulk explosive of the impurity such as mortar, brisance reduces or even loses explosion property, causes dose to waste, and occurs remaining bottom bank, impact demolition effect, increases later stage processing cost.
China Patent Publication No. is that the utility model patent of CN 201672887 U discloses a kind of hole bottom dreg isolator for deep-hole blasting water hole, is the bottom hole medicinal residues isolator of irony disc shape, can play the effect of isolation blast hole base charge and mortar.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, and the deflection that disc shape medicinal residues isolator relies solely on self gravitation can not lead to lose buffer action in bottom hole automatic turning sometimes.
2nd, it is to realize sinking bottom, disc shape medicinal residues isolator diameter must be less than explosion aperture, lead to screed not good from isolator and hole wall gap overflow, isolation effect.
Existing other isolation technology is similar with disc shape medicinal residues isolator, all using bulk explosive and mortar in the heterotypic material isolation blast hole of certain form, generally existing isolator enters hole operation inconvenience, do not adapt to the change of the screed depth, isolation effect is not good, takies hole depth and reduces the defects such as blast hole utilization rate.
Content of the invention
The technical problem to be solved is to provide a kind of aqueous blast hole mortar isolating device and its partition method, solution can must not adapt to the change of the screed depth, isolation effect is not good, take the problem that hole depth reduces blast hole utilization rate, it is effectively isolated explosion in the hole explosive layer and screed, it is to avoid the explosive of blast hole bottom is mixed with mortar and lost efficacy, improve explosive utilization rate, avoid remaining rock bank, save blasting cost.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of aqueous blast hole mortar isolating device, this device includes the batching sphere of hollow being made up of flexible plastic film, slip casting flexible pipe is communicated with the spheroid of batching sphere, in the spheroid of batching sphere, has filled bulk explosive, fill the 90-95% in a diameter of blast hole aperture of the spheroid of bulk explosive.
Thickness >=0.3 millimeter of flexible plastic film.
The method comprises the following steps：
1）Depth h of measurement explosion in the hole screed；
2）Diameter of phi according to blast hole and hole depth H, in conjunction with step 1）Depth h, the diameter of batching sphere needed for calculating and the quantity of the screed of measurement；
3）Make batching sphere：Into the spheroid of hollow, injection bulk explosive, to filling, fills a diameter of step 2 of the spheroid of bulk explosive）Value of calculation, spheroid fills rear enclosed slip casting flexible pipe, that is, makes batching sphere；
4）Put into no less than step 2 to explosion in the hole）The batching sphere of the quantity calculating, batching sphere sinks down into formation sealing coat in screed in Gravitative Loads；
5）Form in the hole explosive layer to explosion in the hole injection bulk explosive, under pumping pressure and batching sphere self gravitation effect, batching sphere is pressurized to be deformed into round pie by spheroidal, the diameter in aperture direction becomes big, and ball wall and hole wall fit tightly；
Realize the isolation of bulk explosive and mortar in aqueous blast hole.
Step 1）The measuring method of depth h of screed be：With long waddy or bamboo cane insertion explosion in the hole until bottom hole, transfer to long waddy or bamboo cane, the mortar trace according to remaining thereon can measure depth h of screed.
Step 3）In, close slip casting flexible pipe using by the knotting of slip casting flexible pipe or the firm method of hot melt closure.
Step 4）In, in batching sphere sinking watching, if meeting blast hole local deformation jam occurs, using waddy, batching sphere is gently disclosed into bottom hole.
A kind of aqueous blast hole mortar isolating device and its partition method that the present invention provides, have the beneficial effect that：
1st, isolating device is the batching sphere using the hollow being made up of flexible plastic film, fill bulk explosive, put into explosion in the hole, under pumping pressure and bulk explosive action of gravity, batching sphere is pressurized to be deformed into round pie by spheroidal, diameter along aperture direction becomes big, and ball wall and hole wall fit tightly, and are effectively isolated explosion in the hole explosive layer and screed, the explosive avoiding blast hole bottom is mixed with mortar and lost efficacy, improve explosive utilization rate, it is to avoid residual rock bank, save blasting cost.
2nd, the batching sphere that flexible plastic film is made, in the non-directional requirement of explosion in the hole, enters and is difficult when hole sinks to the bottom, by blast hole local deformation defective effect, strong adaptability, to enter hole operation simple.
3rd, one or more batching spheres are put into according to the dynamic adjustment of mortar layer depth and form sealing coats, make the height exceed all the time mortar layer depth of sealing coat, can flexible adaptation blast hole screed change in depth it is ensured that isolation effect.
4th, the bulk explosive of injection participates in being injected into the explosive layer of explosion in the hole and jointly explodes acting in batching sphere, and blast hole utilization rate is higher, and controlled blasting is more accurate.
5th, isolating device make simple, easy to use, with low cost, applied widely, have slag, anhydrous have slag or anhydrous no slag blast hole all applicable to there being water.
