Abstract
The invention discloses powder for inhibiting firing and explosion of coal dust. The powder is characterized by comprising calcium carbonate, latex powder and quick-dry powder, wherein the grain size of the calcium carbonate is 100 to 400 meshes, and the mass part ratio of the calcium carbonate to latex powder to quick-dry powder is 100:3-10:3-10. When used, the powder is mixed with water and then sprayed. Compared with the prior art, the powder of the invention has the advantages of good flame retardant effect, good adhesion and the like.
Description
One, technical field
The present invention relates to the powder of a kind of mining inhibition coal dust blast on fire.
Two, background technology
In the coal mining process, under the coal mine because use and the big gun of continuous miner and long wall coal cutter are adopted the coal dust that is flying upward in the tunnel.
Coal dust is the coal dust of fine particle, one of mine five the Nature disasters, the pollution caused by coal dust air, affect the miner healthy, more seriously, when its concentration and oxygen concentration reach certain limit and naked light is arranged coal-dust explosion can occur, its harmfulness is very huge, directly threatens workman's life and national wealth safety.
The measure of existing prevention has: water filling in the coal seam, and at the coal-face spray sprinkler, available ventilation etc., but effect is undesirable.
Three, summary of the invention
The present invention is directed to above weak point, the inhibition coal dust blast powder on fire of a kind of good flame retardation effect, strong adhesion is provided and makes using method.
For achieving the above object, the technical solution used in the present invention is:
A kind of inhibition coal dust blast powder on fire comprises calcium carbonate, latex powder and rapid-curing cutback powder; Wherein said calcium carbonate granularity is the 100-400 order, calcium carbonate: the rapid-curing cutback powder: the ratio of quality and the number of copies of latex powder is 100: (3-10): (3-10).
Calcium carbonate on the one hand can be fire-retardant in this dust, reduces Dust Concentration thereby can effectively coat and adsorb on the other hand coal dust, and rapid-curing cutback powder and latex powder can play adhesive effect, and this powder is bonded on the rib, further suppress the possibility of coal dust combustion explosion.
This shows that the present invention has the advantages such as strong adhesion, anti-flammability be high, simple to operation, is illustrated below in conjunction with the specific embodiment.
Four, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
Calcium carbonate, rapid-curing cutback powder, latex powder are mixed, then encapsulate by granularity requirements and ratio of quality and the number of copies; With this powder with light test after water mixes by the mass parts ratio.
Described latex powder adopts again dispersed latex powder.
Light test: choose many group steel plates, with being coated on the surface of steel plate of coal dust homalographic equivalent, use this powder and water proportionally mixed liquid spray, the steel plate of not used sprinkling dust is organized in contrast, dry the rear alcolhol burner point of using, can in 5 seconds, can light without the control group that sprays, record all the other burning times.
Following table is the specific embodiment and experimental data table:
Powder of the present invention can effectively suppress on fire, the blast of coal dust as can be seen from the above table.
Claims (1)
1. a powder that suppresses coal dust blast on fire is characterized in that: comprise calcium carbonate, latex powder and rapid-curing cutback powder; Wherein said calcium carbonate granularity is the 100-400 order; Calcium carbonate: rapid-curing cutback powder: the ratio of quality and the number of copies of latex powder is 100: (3-10): (3-10).
