Description
Technical field
The present invention relates to the dust collection method that spoil in a kind of underground coal mine chamber is crushed, be particularly suitable for use in underground coal mine dust
The big operation chamber dedusting of amount, depositing dust.
Background technology
In order to reduce the environmental problems such as the subsidence caused by coal mining, by the spoil produced in progress of coal mining
Will gradually expanded application for goaf backfill reduction subsidence.It is mined out backfilling because the size of spoil differs
Usually require spoil being crushed to some scale before area.For a long time, the crushing of spoil is general completes on ground, and this is accomplished by
Spoil is first transported to earth's surface, underground is transported to after crushing again and implements filling, so as to increase substantial amounts of lifting cost.In order to reduce
Cost is lifted, chamber can be crushed in underground construction spoil, implement spoil crushing, it is to avoid spoil gug.The crushing of spoil is production
The great operation of dust quantity, due to underground coal mine narrow space, the dust of generation is difficult to trap, and a large amount of dust is caused greatly to workman
Injury, traditional dust falling in coal mining method mainly have pre-wetting spoil, water spray, spraying, using dedusting machine etc., although these
Dust Capacity can be reduced to a certain extent, but effect is still undesirable.
The content of the invention
Technical problem：The present invention invents spoil powder in a kind of underground coal mine chamber by combining underground coal mine ventilating system
Dust, the mine return air system of unmanned entrance is directly discharged into by mine ventilation system so that dust is or not broken dust collection method
Into operating area, harm of the reduction dust to people.
Technical scheme：The dust collection method that spoil is crushed in a kind of underground coal mine chamber of the present invention, comprises the following steps：
A. construction connects the crushing chamber of air intake lane and return airway between air intake lane and return airway；
B. air exhauster is installed in return airway, the air duct of air exhauster is connected with crushing chamber；
C. the regulation door of side installation one that chamber is connected with return airway is being crushed；
D. a pulverizer is installed crushing in chamber, crush chamber and be connected side with air intake lane provided with being connected with pulverizer
Enter cash belt and to go out cash belt, pulverizer be shipped for through entering cash belt by downhole gangue, pulverizer crush after spoil through going out cash
Belt transports chamber, carries out downhole gangue backfill；
E. during spoil is crushed in pulverizer, by air exhauster exhausting, the air pressure in control air intake lane is higher than back
Air pressure in air way so that distinguished and admirable to flow into return airway by the size-reduced chamber of air intake lane, carries out dedusting.
The regulation door includes two parts up and down, and top is divided into brickwork construction, is reserved with the circular hole for passing through air duct, air duct
Combined closely with circular hole, bottom is the left and right sliding door coordinated with top split-phase.
In the case where being not turned on air exhauster by adjusting the aperture of sliding door come airflow regulation from the size-reduced cave of air intake lane
Room flows into the wind speed of return airway, realizes dedusting.
Beneficial effect：The present invention is by improving mine ventilation system, and chamber is crushed in design between air intake lane and return airway,
So that spoil turnover is all in the upwind of pulverizer, air is than comparatively fresh, and it is then direct to crush the dust produced during spoil
Stream enters workman in air return system, whole process and is not exposed to dust with the wind, has ensured workers ' health.The invention enables spoil powder
It is broken directly to be carried out in underground, the lifting cost of mine is reduced, while dedusting depends on improvement on Ventilation System, is reduced
Input in terms of dedusting equipment.Present invention operation is upper simple and easy to apply, and effect significantly, there is significant economic benefit and promotion price
Value.

Embodiment
The embodiment to the present invention is further described below in conjunction with the accompanying drawings：
Below the dust collection method that spoil is crushed in the underground coal mine chamber of the present invention, specific steps：
A. construction connects the crushing chamber 9 of air intake lane 4 and return airway 5 between air intake lane 4 and return airway 5；
B. air exhauster 7 is installed in return airway 5, the air duct 6 of air exhauster 7 is connected with crushing chamber 9；
C. the regulation door 8 of side installation one that chamber 9 is connected with return airway 5 is being crushed；The regulation door 8 includes two up and down
Point, top is divided into brickwork construction, is reserved with the circular hole for passing through air duct 6, and air duct 6 is combined closely with circular hole, and bottom is and top
The left and right sliding door 10 that split-phase coordinates.
D. install a pulverizer 1 crushing in chamber 9, crush chamber 9 be connected with air intake lane 4 side provided with and pulverizer 1
It is connected to enter cash belt 2 and go out cash belt 3, pulverizer 1 is shipped for through entering cash belt 2 by downhole gangue, after pulverizer 1 is crushed
Spoil transports chamber through going out cash belt 2, carries out downhole gangue backfill；
E. during spoil is crushed in pulverizer 1, by the exhausting of air exhauster 7, the air pressure in control air intake lane 4 is higher than
Air pressure in return airway 5 so that distinguished and admirable to flow into return airway 5 by the size-reduced chamber 9 of air intake lane 4, carries out dedusting.It is being not turned on exhausting
In the case of machine 7 return airway 5 is flowed into by adjusting the aperture of sliding door 10 come airflow regulation from the size-reduced chamber 9 of air intake lane 4
Wind speed, realizes dedusting.
As shown in figure 1, air intake lane 4 and return airway 5 are necessary tunnels during mine normal production, cave is crushed in construction
Exist before room 9, chamber 9 is crushed in construction between air intake lane 4 and return airway 5, and the size for crushing chamber 9 must be able to simultaneously
The requirement for installing pulverizer 1, entering cash belt 2 and going out cash belt 3 is met, the connection air intake lane 4 of chamber 9 and return airway 5 is crushed；Returning
Air exhauster 7 is installed in air way 5, air exhauster 7 is connected through air duct 6 with crushing chamber 9；It is distinguished and admirable from air intake lane 4 to return air in order to adjust
Lane 5 flow speed, crush chamber 9 be connected with return airway 5 side be installed on regulation door 8, adjust door 8 be made up of two parts,
Top is brickwork construction and a reserved circular hole, and circular hole, which is generally stayed, to be located at the top lateral wall of regulation door 8, and air duct 6 passes through circular hole simultaneously
Combine closely, prevent from existing between air duct 6 and circular hole space and gas leakage, regulation door 8 bottom is installed on sliding door 10, sliding door 10
The aperture of door can be adjusted；Crush chamber 9 in install pulverizer 1, bulk spoil can be ground into preferable granularity so as to
For bashing, regulation door need not be installed by crushing the side that is connected with air intake lane 4 of chamber 9, but is equipped with into cash belt 2
With go out cash belt 3, spoil is transported to pulverizer 1 through entering cash belt 2, and the spoil after crushing transports chamber through going out cash belt 2；In powder
During broken machine 1 crushes spoil, close sliding door 10, open air exhauster 7 carry out exhausting so that it is distinguished and admirable by air intake lane 4 through powder
Broken chamber 9 flows into return airway 5, and the distinguished and admirable dust that pulverizer 1 is crushed spoil and produced brings the return airway 5 of unmanned entrance into, from
And workman can be in fresh distinguished and admirable middle work from the harm of dust.The air pressure in air intake lane 4 is higher than return air under normal circumstances
Air pressure in lane 5, can also be by adjusting the aperture of sliding door 10 come airflow regulation from entering in the case where being not turned on air exhauster 7
The size-reduced chamber 9 of air way 4 flows into the wind speed of return airway 5.
