Abstract
The utility model belongs to pit mining technical field, and in particular to a kind of coal mine long distance driving dash system, including blast pipe, gate support frame, it is characterised in that: air inlet tube end is installed into blower；Blast pipe is fixed on the upside of the left or right side of gate support frame by U-bolt, and gate support frame is evenly spaced on as digging laneway constantly extends；There is through-hole on blast pipe uniformly at intervals；The accessory fan of connection air hose is additionally provided on blast pipe, accessory fan is fixedly installed on gate support frame.The beneficial effects of the utility model are: by mine ventilation and support be combined into one, with mine laneway tunnel progress, arbitrarily change increase wind composite structure；Uniformly distributed through-hole realizes ventilation exchange thoroughly, does not retain detention space, operational safety and economy for gas.
Description
Technical field
The utility model belongs to pit mining technical field, and in particular to a kind of coal mine long distance driving dash system
System.
Background technique
Mine ventilation system, which is undertaken, provides fresh air volume, discharge underground toxic and harmful gas function, produces for underground coal mine
Activity provides particularly important safety guarantee.Good ventilating system can not only ensure production safety, should also have to wind
The good characteristics such as controllable in real time, the simple, method of operation economy of operability of amount.For at present, traditional ventilating system is typically all
Blower is set in air inlet, distinguished and admirable is passed through to operating location by being continuously increased air duct length by fresh.However, along with mine
The continuous expansion of the exploitation scale of well, tunnel length is increasingly longer, and tunnel windage is also increasing, and air quantity demand is increasing,
Conventional dash mode is increasingly difficult to meet the ventilation requirement in long distance driving tunnel.
Therefore, in order to meet many requirements of ever-expanding production scale, it is necessary to which a kind of performance is comprehensive, economical operation
Long distance driving dash system.
Utility model content
The utility model is mentioned above in order to solve the problems, such as, makes up the deficiency of traditional technology, provide a kind of coal mine it is long away from
From digging laneway aerating system, by mine ventilation and support be combined into one, change and increase wind composite structure, solve long range lane
Road ventilation difficult problem, realizes the purpose of ventilating system operational safety economy.
The utility model is achieved by the following technical solution:
A kind of coal mine long distance driving dash system, including blast pipe, backwind tube and gate support frame enter the wind pipe end
Air inlet fan is installed in portion, and air inlet fan is fixed on digging laneway inlet, is not extended with tunnelling and is moved；Blast pipe passes through U-shaped
Bolt is fixed on the upside of the left or right side of gate support frame, and gate support frame is with the continuous uniform intervals cloth of the extension of digging laneway
If；The accessory fan of connection air hose is additionally provided on blast pipe, accessory fan is fixed on gate support frame.
The blast pipe is spliced by the steel pipe series winding of certain length, and end junction is provided with gasket.
The wind direction of the accessory fan is consistent with air-flow direction in air hose.
The blast pipe is independent tubes, is not in communication with the outside.
The beneficial effects of the utility model are: by mine ventilation and support be combined into one, blast pipe connects uniformly distributed
Gate support frame realizes the purpose of firm gate support frame.Meanwhile gate support frame also provides support force for air hose, especially
Accessory fan is easy for installation, with the mining progress of mine, arbitrarily changes and increases wind composite structure, it is more next effectively to solve digging laneway
Problem longer, windage is increasing, air quantity demand is increasing；Blast pipe is distributed in the left or right side of gate support frame
Side, uniformly distributed through-hole realize ventilation exchange thoroughly, do not retain detention space, operational safety and economy for gas.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the gate support frame structure diagram with accessory fan.
In figure, 1 air inlet fan, 2 blast pipes, 3 blast pipe accessory fans, 4 gate support frames, 5 through-holes, 6U type bolt.
Specific embodiment
Attached drawing is a kind of specific embodiment of the utility model.
The coal mine long distance driving dash system of the utility model, including blast pipe 2, gate support frame 4, blast pipe
2 ends are installed by air inlet fan 1；Blast pipe 2 is fixed on the upside of the left or right side of gate support frame 4 by U-bolt 9, gate support
Frame 4 is evenly spaced on the extension of digging laneway；There is through-hole 5 on blast pipe 2 uniformly at intervals；It is additionally provided on blast pipe 2
It is connected to the accessory fan of air hose, accessory fan is fixed on gate support frame 4.The blast pipe 2 by certain length steel pipe string
Company is spliced, and end junction is provided with gasket.Air-flow direction in the wind direction and air hose of the accessory fan
Unanimously.The blast pipe 2 is independent tubes.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is it should be appreciated that the description of the embodiments and the specification only illustrate the principle of the present utility model, not
Under the premise of being detached from the spirit and scope of the utility model, the utility model also has various changes and improvements, these change and change
Into falling within the scope of the claimed invention.The utility model requires protection scope by appended claims and
Its equivalent thereof.
