Description
Technical field
The present invention relates to underground mine treating flour dust fields, and in particular to a kind of mining Dead working face explosion dedusting system
System.
Background technique
Currently, underground mine driving face bursting work treating flour dust mainly uses based on atomizing de-dusting at present, mainly
Hydrous taphole loam dust-settling technology and High Pressure Spray for Dust Suppression technology.Water stemming material dust-settling technology mainly forms water mist in explosion moment and inhibits powder
The generation of dirt, High Pressure Spray for Dust Suppression technology is mainly when the dust that bursting work generates flows to tunnel external diffusion with the wind to distinguished and admirable
It is purified.The dust that these dedusting technologies generate explosion plays preferable regulation effect, to improvement working environment at coal mines
Play important function.
But with the increase of mining rate, the dust concentration that explosion generates is also increasing, and mining depth increases, ore-rock
Firmness coefficient be also stepped up, explosion generate dust in respirable dust concentration accounting it is also increasing.Using water cannon
Mud dust-settling technology is only capable of playing 20%~50% dustfall efficiency, and High Pressure Spray for Dust Suppression dedusting technology is directed to respirable dust
It is only capable of playing 85% or so dustfall efficiency, dust concentration is still unable to reach the dust concentration of requirements of the national standard after improvement
Value.With the increasing of supervision of occupational health dynamics, operating personnel improves the attention rate of own bodies health, mining excavation operation
It is badly in need of a kind of dedusting technology of applicable high dustfall efficiency in face.
In addition, being directed to metal and nonmetal mine, only head blasting face quantity is more, and dust concentration is big, and contaminated area is wide, one
As dust pelletizing system be only capable of being administered for single working face, all working face administer simultaneously caused by economic cost it is huge
Greatly, therefore, it is necessary to a kind of moveable flowing dust pelletizing systems to administer to only blasting face dust.
Summary of the invention
In order to overcome above-mentioned defect existing in the prior art, the object of the present invention is to provide a kind of high dust collection efficiency, can
The mining Dead working face explosion dust pelletizing system of mobile operational process.
In order to realize above-mentioned purpose of the invention, the present invention provides a kind of mining Dead working face explosion dust pelletizing system,
Including travelling on the truck in tunnel, further includes the wet scrubber being set on truck, is that wet scrubber circulation supplies
