Abstract
The invention discloses consolidation water stemming for blasting blockage, which is formed in such a way that mixed powder is placed in a bag body, and is sealed and soaked in water, wherein the mixed powder comprises the following components in part by weight: 10-15 parts of attapulgite, 6-12 parts of chlorinated lime, 3-5 parts of gypsum, 1-3 parts of resin sweller and 0.1-0.4 part of sodium dodecyl sulfate; and the bag body is made of permeable papers. The consolidation water stemming has the advantages of simplicity and convenience in operation and low production and use cost; and the water curtain formed after explosive explosion can play a role of settling dust, degrading poisonous and harmful gas, dampening flame, reducing temperature and the like, and particularly, greatly reducing risks caused by methane gas accidents.
Description
Technical field
The present invention relates to a kind of explosion obstruction stemming, particularly a kind of explosion and stop up and use fixed water stemming material, be applicable to the drilling and blasting operation places such as mine working, Hydraulic Tunnel, traffic tunnel.
Background technology:
Stemming is used for drilling and blasting operation place shutoff gun muzzle and uses, because stemming itself has certain quality, the explosion gases that rushes at the aperture when therefore it can be to explosive charge plays retardation, so that the time lengthening of hole inner high voltage gas effect, thereby strengthen blasting effect.On the other hand, stemming also makes the explosive reaction more abundant to the retardation of explosion gases, thereby reduces the generation of toxic gas.
At present the blasting operation scene generally all is to fetch earth and carry out the big gun hole plug in the employing scene, and the difficulty because most of operation fields, particularly underground mine, desert region etc. fetch earth is added the stemming trouble, taken a lot of work, and therefore substantially all adopts at present without the obstruction explosion.Not only blasting cost is high without stopping up explosion, and blasting effect is poor, and toxic gas content increases, and shotfiring safety is difficult to guarantee, therefore develop a kind ofly stop up conveniently, obstruction is effective, production cost is low stemming tool is of great significance.
The water curtain that water stemming material forms behind explosive charge can play the effects such as depositing dust, degraded obnoxious flavour and flame arrest cooling, particularly contains the gas driving face, uses water stemming material, can greatly reduce the risk of gas accident.
Summary of the invention
The object of the present invention is to provide a kind ofly stop up conveniently, obstructions is effective, production cost is low, the fixed water stemming material of the explosion of good environmental protection obstruction.
For achieving the above object, explosion provided by the invention is stopped up with fixed water stemming material employing mixed powder is put into bag, entering water soaking behind the envelope makes, described mixed powder comprises following component: attapulgite, chlorinated lime, gypsum, resin swelling agent and sodium laurylsulfonate, described bag adopt permeable paper to make.
The weight proportion of above-mentioned each component of mixed powder is: 10～15 parts of attapulgites, 6～12 parts in chlorinated lime, 3～5 parts in gypsum, 1～3 part of resin swelling agent, 0.1～0.4 part of sodium laurylsulfonate.
It is 3～5min that the above-mentioned bag that mixed powder is housed enters water-soaking time.
The fixed water stemming material of the present invention both can adopt in the production scene and soak, and also can adopt at the explosion scene and soak, and prepared water stemming material has certain solid shape.
The present invention has following effect:
(1) obstruction is easy and simple to handle, and use cost is low;
(2) can improve blasting effect, reduce Poisonous Gas;
(3) water curtain that forms behind the explosive charge can play the effects such as depositing dust, poisonous, the obnoxious flavour of degraded and flame arrest cooling, particularly can greatly reduce the risk of gas accident;
(4) be easy to produce and transport, production cost is low.
