Abstract
The invention discloses a salt water stemming. Saline solution is injected into a cylindrical plastic pipe, the mouth of which is sealed and blocked in a heat seal way, which plays a role in inhibiting gas combustion, explosion in the blasting engineering of the coal mine.
Description
Technical field:
The present invention relates to the device in the blasting engineering, mainly be applicable to the colliery blasting engineering of gas, coal dust.
Background technology:
At present, common use water stemming material in the colliery blasting engineering, bubble mud are the rectangular circular bags that forms through folded mouth, heat seal cutting with bilayer film, during use, the workman injects fresh water at the scene in bag, rely on the interior hydraulic pressure compacting of bag at the inside folded stack film seal of sack portion.The shortcoming of water stemming material is: (1) sack shutoff is not tight, and drainage is arranged; (2) bag is too soft, is difficult for sending in borehole; (3) efficient of elimination coal dust, gas is low, still has a lot of coal dusts, gas to enter in the air after blowing out.
Summary of the invention:
For overcoming the shortcoming of background technology, the present invention propose a kind of easy to use, fast, brine stemming efficiently.
Shell adopts the cylindrical plastic pipe, injects saline solution in the pipe, adopts hot bonding method to seal, and the optium concentration of saline solution is 30% to 35%.
The present invention compares with background technology, its advantage:
(1) easy to use, quick, because of brine stemming is a finished product, the workman directly uses, and plastic casing has certain degree of hardness, send in borehole easily.
(2) seal tightly, avoided drainage.
(3) flame arrest is effective, has reduced the probability that ignites of gas and coal dust.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention
Accompanying drawing 2 is the structural representation of background technology
The specific embodiment:
Shell 1 is the cylindrical plastic pipe, the salt solution 2 that injects in the pipe is aqueous solution of alkali metal salt, and alkali metal soln is to be mixed by fresh water and alkali metal salt, mixes after the back that stirs is injected in the pipe, use the heat-sealing machine heat sealing, alkali metal salt is NaCl, KCl, BaCl
2, CaCO
3, K
2CO
3, Na
2SO
4, experiment showed, that these alkali metal salts can make the gas ignition temperature bring up to 800 ℃ by 670 ℃, inhibitory action is played in burning, the blast of gas.Optium concentration after alkali metal salt and the mixing of fresh water is 30% to 35%.
Claims (2)
1, a kind of brine stemming is characterized in that: in the cylindrical plastic pipe, inject saline solution, mouth of pipe heat seal shutoff.
2, brine stemming according to claim 1, the optium concentration that it is characterized in that saline solution is 30% to 35%.
