Description
Technical field
The utility model relates to a kind of mine underground tunnel cleaning device, particularly relates to a kind of underground coal mine multi-stage, energy-saving tunnel cleaning device.
Background technology
In progress of coal mining, mine dust is one of large disaster in colliery five.
Dust not only has the potential danger of blast, also has and reduces service life of equipment and precision, reduction production scene visibility, and the risk that the staff contacted with dirt source for a long time suffers from occupational disease (e.g., pneumoconiosis) such as significantly to raise at the harmfulness.
In coal production process, nearly all operation all may produce dust.The digging production technology that particularly highly efficient and productive mechanization degree is higher, the dust in the air of its underground work point maintains higher concentration all the time.
In progress of coal mining, underworkings is pedestrian, vehicle borne primary location, and the quality of tunnel environment directly affects the healthy of staff, and the local area high in dust concentration brings inconvenience in construction operation difficulty to underground work.
For effectively controlling and the dust pollution question solved in progress of coal mining, effectively to improve underground construction operating environment, for many years, domestic and international scientific worker has carried out a large amount of Exploration & stu dy, propose the control of a series of Mine Dust theoretical, and carried out the aspect improvement such as a large amount of excavated technology technology, open air exhaust equipment and cleaner, at how dust-proof, depositing dust, and effectively the control aspect such as dirt and dedusting achieves the progress of going up largely.But, in underground construction operation process, concrete working condition is severe after all, dirt source is multi-point and wide-ranging, dust Producing reason is complicated and changeable, the problem of dust pollution is difficult to realization and effects a radical cure completely, in actual production process, the problem of dust pollution is still comparatively serious, and underground construction operating environment is still comparatively severe.
As a kind of tradition but very easy and effective technological means, water is used to spray the depositing dust of (spraying or water spray) timely to each dirt source point and dedusting technology means obtain general continuing to use always.In prior art, in coal mine roadway, the method for cleaning, dedusting mainly contains following three kinds:
One is, by sprinkler.Such as, Chinese patent application CN204283475U discloses a kind of liftable and washes away dust suppression device, it adopts vehicular form of structure, be specially, water pump, water tank are arranged on mining rail chassis, the water pipe of pump outlet connects the shower nozzle of some quantity, wherein water pipe is supported by mounting bracket and has the technological means such as elevating function, achieves and can wash away dedusting to wall; And (due to liftable, Height Adjustable) be applicable to all size tunnel (mainly referring to the height in tunnel) wash away dedusting.
But it is very narrow that the dust collection method scope of application is washed away in this packaged type (vehicular) tunnel, and effect is also undesirable.Reason is, lane space is narrow, base plate uneven, and sprinkling truck carries out moving difficult in tunnel, washes away dedusting and there is many dead angles.What is more important, sprinkling truck is filled with water limited, can not realize continuous watering, and life period postpones.Dedusting is washed away in the tunnel that this method is only only applicable to " emergency " temporarily.
Two are, manually sprinkle water.Shortcoming is time and effort consuming, and efficiency is low; Watering atomizing effect is poor, destroys subsurface environment; Part return aircourse, particularly special return aircourse cannot enter.Thus cause laying dust thickness to reach as high as ten centimetres, serious threat mine safety.
Three are, adopt fixed point spray pattern to sprinkle water, that is, spray in the set-point, cross section, tunnel of certain distance.Shortcoming, can not realize all section cleanings; Carry out Based Intelligent Control according to automatic control equipment, each point needs to install electromagnetic switch, and power circuit, communication line are various, easily break down under the specific operation condition of down-hole.

Embodiment 1
For the long 300m in tunnel, dividing three grades and wash away district, take work plane as initial point, and front 100m is three grades of cleaning areas (low pressure pool 1MPa, this region all shower nozzle settings threshold value is below 1MPa);
100-200m is secondary cleaning area (middle pressurized water district 2MPa, this region all shower nozzle settings threshold value x is: 1MPa<x<2MPa), 200-300m is that (high pressure pool 3MPa, this region all shower nozzle settings threshold value x is: 2MPa<x<3MPa) in one-level cleaning area.
Illustrate: the threshold value of setting and wash away progression, suitably can adjust according to different mine conditions.
Tunnel cleaning starts, and first setting high-pressure hydraulic pump pressure is 1MPa, washes away district's shower nozzle threshold value be less than 1MPa near three grades of work plane, and namely hydraulic pressure is greater than three grades and washes away district's shower nozzle threshold value, and three grades are washed away district and automatically start spray for dust suppression 2min;
Then regulate high-pressure hydraulic pump pressure to 2MPa (hydraulic pressure is greater than secondary and washes away district's shower nozzle threshold value), secondary washes away district and starts the 2min that sprays, and period three level is washed away district and continued to wash away;
Then, again adjustment high-pressure hydraulic pump pressure is adjusted to 3MPa (hydraulic pressure is greater than one-level and washes away district's shower nozzle threshold value), one-level is washed away district and is started the 2min that sprays, period secondary, three grades wash away district and continue to wash away.
Close high-pressure hydraulic pump, stop tunnel cleaning, spray time can be determined according to the dust situation in concrete tunnel.
If Dust distribution three grades of mainly concentrating near work plane wash away district, dust is not also diffused into secondary, one-level washes away district, setting high-pressure hydraulic pump force value is only needed to be 1MPa, spray for dust suppression is carried out for the emphasis dust pollution district near work plane, secondary, one-level wash away district without the need to washing away, with using water wisely.
