Description
Technical field
The present invention relates to a kind of surface mine Dust Control Technologies, and in particular to a kind of opencut standing dust depositing dust
System and dust-removing method.
Background technique
Blasting in open-pit operation process, ore-rock by explosive blasting enormous impact pressure, high temperature and stress wave activity and
It crushes, displacement, forms dust after explosion, raised with explosion air-flow.Its dust-producing amount is big, and dust concentration moment can reach 1500-
2000mg/m3；Dust diffusion zone is wide, distance is remote, pollutes to surrounding enviroment big.
In addition, outdoor pit temperature inversion causes pit inner air and outer air that cannot flow freely, hinder to produce in opencut pit
Raw dust is gathered in pit to external diffusion, is continuously increased dust concentration in pit, air quality deteriorates rapidly, and quick-fried
Bankruptcy dirt adsorption toxic and harmful gas, harm to the human body is larger, seriously affects opencut normal operation and employee's body is strong
Health.Although in the prior art there is dust suppression to be sprayed big gun and dust suppressant, lack effective dust suppression means, but do not obtain abundant benefit
With outdoor standing dust-laying effect is undesirable.
Summary of the invention
The first object of the present invention provides one kind aiming at the deficiency of standing area dust-laying effect difference in the prior art
Efficient and safe opencut standing dust dust falling system.The system is by sending fog gun machine to be located at movably distance air
On trolley, and the structure that can be horizontally rotated is formed by turntable, effectively to expand depositing dust range, improves dust-laying effect, meanwhile, just
In long-range control, it is ensured that safety.The second object of the present invention is to provide a kind of dust-removing method, and this method is based on aforementioned depositing dust system
System is implemented, it is ensured that safe and efficient realization standing area depositing dust purpose.
In order to realize that the first purpose, the present invention use following first technical solution.
A kind of safe and efficient dust falling system of opencut standing, including distance air send fog gun machine, and distance air send fog gun machine
It is located on trolley by rotating horizontally turntable；The car body top of trolley is equipped with protective frame；The distance air send fog gun machine to pass through water

It is connected to the delivery pipe for connecting with external dust suppression source of solvent；Distance air send fog gun machine to be connected with for external power supply and remotely
Control the cable of equipment connection.
Using the present invention of preceding solution, fog gun machine atomizing de-dusting is sent by distance air, passes through the pitching of gun barrel itself
Angular adjustment and horizontal rotation turntable rotation, it can be ensured that accurate covering standing region, and blast area depositing dust is made not stay dead angle,
Ensure dust-laying effect；, in safety zone remote opening fog gun machine, dust suppression solution wetted can be kept quick-fried by when explosion counts down second
Broken region surface ore-rock and dust, meanwhile, misty dust suppression liquid dispersion is covered on ore-rock overhead, and forms mesh enclosure shape, makes explosion powder
Dirt is not raised or is just captured when just raising, flocking settling.Wherein, protective frame can effectively avoid the hit fog gun machine core of slungshot
Part；Fog gun machine, which is located on trolley, flexibly to be fast moved, quickly prepare and come into operation in opencut region, it can be ensured that explosion
Construction progress.
Preferably, the fender bracket is equipped with ceiling, and ceiling send the formation of fog gun machine to block the distance air from top.With shape
The good protection of pairs of big gun mist machine, it is ensured that falling rocks does not injure parts.
Preferably, the horizontal rotation turntable is connected with rotary drive motor by worm screw worm gear drive mechanism；It is described outer
Portion's power supply and remote control equipment can also be connect by the cable with rotary drive motor.So that every big gun mist machine is formed
Large range of dust suppression region.
In order to realize that the second purpose, the present invention use following second technical solution.
A kind of opencut standing dust-removing method, including being wrapped on the open pit bench of standing area peripheral edge in half
The dust falling system of more realization first invention purposes of the arrangement enclosed, and pass through delivery pipe for water pump and the external dust suppression solution body
Source connection, and connect external power supply and remote control equipment with the dust falling system by cable；And it falls to count in explosion
When the several seconds, by the control opening of device dust falling system for being located at safety zone.
Using the present invention of preceding solution, half-surrounded is formed in standing area peripheral edge by multiple dust falling systems
Arrangement, the distance air of each dust falling system send fog gun machine while implementing atomizing de-dusting, passes through the pitch angle tune of gun barrel itself
Section and horizontal rotation turntable rotation, it can be ensured that the whole region of accurate covering standing drops standing area by all standing
Dirt, without staying dead angle, it is ensured that dust-laying effect；And when explosion counts down second (usually by execution in 30 seconds or so), in safety zone
Remote opening fog gun machine makes dust suppression solution wetted burst region surface ore-rock and dust, so that blast area surface wettability, is reduced quick-fried
Broken dust；Meanwhile misty dust suppression liquid dispersion is covered on ore-rock overhead, and forms mesh enclosure shape, and blasting dust is made not raise or just raise
It is just captured when rising, flocking settling.
It preferably, is the mixture of water and dust suppressant for the dust suppression solution of depositing dust.It can be constructed according to live ground
Situation, which carries out concentration adjustment, can achieve the purpose that rapidly and efficiently dust suppression to make full use of the coalescence and bonding characteristic of dust suppressant,
Dust suppressant dosage can be rationally reduced again, reduce dust suppression cost.
Preferably, two be arranged in the more dust falling systems of standing area peripheral edge are laid in loosening in opposite directions
On the same level-one step of burst region two sides, remaining is laid on upper level step.Sufficiently to cover standing region, and
Being formed, there is the dust falling system of difference in height to arrange, and then realize depositing dust twice, further increase anti-dust effect.
Compared with the prior art, the invention has the beneficial effects that: dust falling system structure is simple, easy to use, safe,
Dustfall efficiency is high；Dust-removing method strong operability, dust-laying effect is good, and can universe covering.
