Description
The invention belongs to the improvement of the used equipment of a kind of shot hole blasting method.
Before the present invention made, the charge constitution of shot hole blasting was normally at big gun hole base charge volume both at home and abroad, and powder stick is stifled full with yellow mud (using several water stemming materials sometimes) to the big gun aperture.［ seeing " colliery blasting technology question and answer ", in December, the 1978 front page first impression, the 60th page ］.
For a long time, people are used to build underground engineering to this charge constitution, and multiple occasions such as mining tunneling are because the strength of shot hole blasting is big, the worker leads height, speed is fast, cost is low, therefore, shot hole blasting also can adopted by people in a quite long period from now on widely.
But, utilize this charge constitution to carry out explosion, also there are some problems at present, mainly be must have the gap between powder stick and the big gun hole wall, will cause the channel effect that detonation is propagated, cause partly quick-fried; Active force in the time of can making explosive charge on hole wall is much smaller than detonation pressure, the gas that may ignite when building up gas, explosive charge easily in this gap, causes gas and dust explosion; This gap makes the propagation conditions of explosive charge in the big gun hole be similar to its propagation conditions in atmosphere, and the cut off diameter of powder stick is bigger; In the photoface exploision operation, explosive is very inhomogeneous along big gun hole axial distribution, and is very unfavorable to photoface exploision.
With yellow mud, sand (adding several cement big guns sometimes) shutoff big gun hole,, influence the crushing effect of shotfiring safety and explosion because the effort, time-consuming, bothersome that operates makes the shutoff difficult quality reach designing requirement.Yellow mud itself can not to all the winds transmit the pressure that equates as desirable fluid, has more aggravated the unbalance stress of big gun hole wall, influences demolition effect.General very not cheap in the mine, the yellow mud sand source of goods very easily, cost is higher.
Utilize this charge constitution in a single day to produce blown-out shot, deal with not only bothersome, but also dangerous, just in case the generation detonation, just can not be from horizontal blanking, have to cause and catch fire, cause the danger of gas and dust explosion; The gas in case ignite in the part will cause large-area gas and dust explosion, and can not utilize the propagation of explosion blocking-up gas explosion itself.
Just can't insert the big gun hole when water stemming material water-filling that uses is sufficient now, it designs external form, makes water stemming material can not be full of whole big gun hole fully, and this is all very unfavorable to smoke abatement and dust control and explosion and crushing effect.
Blasting fume and dust that this charge constitution produces are bigger.
The object of the present invention is to provide seed capsules dress thing, can more easily be full of the whole spaces except that explosives such as explosives and detonators in the big gun hole to water, eliminate the gap that exists between powder stick and the big gun hole wall, obtain good demolition effect.
The present invention is an explosion water jacket, as shown in Figure 2.Make by collapsible, fluid-tight flexible material, can oneself overlap double-deck (such as making) with more pliable and tougher plastic sheeting.The structure of water filling port is identical with the structure of former water stemming material water filling port.Just its water filling port is located at self place near the length middle part.Be full of after the water, its diameter should be bigger 1 to 4 millimeter than blasthole diameter, so that it also can fully be adjacent to the big gun hole wall when irregular in the big gun hole.Its length adds 3 times of blasthole diameters to 2 times big gun hole length at 2 times of big gun hole lengths and adds 3 times of blasthole diameters and add between 50 centimetres again.(the big gun hole length here refers to big gun hole design length).Its structure as shown in Figure 2.
During use, should in water jacket, annotate a certain amount of water earlier, to reduce the friction between the two membranes.Then, with a thinner smooth tamper, with the powder stick water jacket of packing into, as shown in Figure 3.(if the heel near vertical is downward, and the outside of last powder stick also will be put a very light thing of hollow plastic bottle one class proportion again, and the mean specific gravity that makes it and explosive is less than water).Then, with tamper explosive belt the explosion water jacket and send into the big gun hole simultaneously, direct reach at the bottom of the hole.Then, one side is taken out tamper gently outward.One side is toward the interior water filling of explosion water jacket.Tamper is extracted out fully, fills with after the water, even if charging work has been finished.As shown in Figure 4.Like this, the water in the explosion water jacket just has been full of in the big gun hole except the whole spaces beyond the explosives such as explosives and detonators.
Adopt this charge constitution to carry out blasting work following superiority arranged:
Be full of water between Explosive roll and the big gun hole wall, just overcome the channel effect that detonation is propagated fully, increased the active force of explosive charge on the big gun hole wall, also eliminated the condition that gas is built up in the big gun hole, guaranteed can not cause gas and dust explosion thus.Because what powder stick can be done very carefully also can guarantee steady detonation, when being used for photoface exploision, explosive is more evenly distributed along the big gun axially bored line, very favourable to photoface exploision.Like this, just can replace low explosion velocity with orthodox explosive.Low density explosive.Can utilize the blast energy of explosive more fully, save explosive.
Water filling operation of the present invention was compared with former stem operation, laborsaving, save trouble, save time, filling quality reaches designing requirement easily, can make water be full of the whole spaces except that explosives such as detonator, explosive in the big gun hole, explosive force spread in all directions explosive charge produces makes whole big gun hole wall stressed more even.Because the water yield that the present invention injects is about three times of water stemming material, has just increased the opposing of heel direction, stop detonation gas excessive too early, increase blast and generate the working application time of gas in the big gun hole.Water generates gas to blast and is rolled in middle, absorb the heat of detonation gas, reduce its temperature, the water expansion of then gasifying itself participates in acting, and enters prior to detonation gas in the crack of coal body (or rock), enter in the atmosphere, play and reduce gas and coal dust concentration, reduce gas temperature, increase the effect of the humidity of air.So,, can not cause gas and dust explosion even have enough gas in the coal body crack or in the atmosphere yet.
Sodium chloride before water of the present invention has replaced is not only reduced the explosive force problem by tube, does not have sodium chloride smog pollution problem yet, also can absorb pernicious gas and flue dust that explosive charge produces in large quantities, adsorbs dust in large quantities, and pollution controls environment.
If the blast of detonator does not cause explosive detonation, but cause that explosive catches fire, the one, that near the water jacket internal layer membrane the detonator is fried broken during blasting cap detonation, water can flow to fire soaked and go out; The 2nd, during explosive inflammation, can burn the internal layer of water jacket brokenly, water also can flow to flame soaked and go out; The 3rd, isolated fully because explosive inflammation is to carry out in explosion water jacket internal layer the inside with gas, coal dust, air, can not cause gas and dust explosion, can not cause fire.So, even detonation takes place, also can oneself cease very soon and go out, can not cause major break down.Handle this detonation big gun hole or blown-out shot, as long as the water in the water jacket is bled off, just can haul water jacket explosives and detonators is taken out the big gun hole together easily, the big gun hole can also utilize again.Than convenient with the pre-treatment blown-out shot, safety.
Compare with yellow mud, sand, have abundant water resources on the mine, it is few to spend, and it is also convenient to carry.
