Description
Technical field
The present invention, which relates to, belongs to Coal Mine Fire calamity technical field, is particularly used for the gas sampling dress of coal mine gob
It sets and its application method.
Background technique
Mine fire is one of coal mine major casualty, and the coal mine in China 56% has spontaneous fire, wherein mined out
Area's spontaneous fire accounts for the principal status of public economy, generally according to situation of leaking out, will adopt
Dead zone is divided into cooling zone, oxidized zone and suffocative zone, and the accurate position for grasping three band of spontaneous combustion is to taking specific aim fire extinguishing
Measure is extremely important.During dividing goaf " three band of spontaneous combustion ", it is important that a step be analyze goaf various gases
Concentration, gas needs to be transported to the detection that gas content is carried out in analytical equipment by the beam tube that is laid in goaf
Analysis, therefore the accuracy of testing result is most important in " three band of spontaneous combustion " division.Traditional approach generally uses beam tube to carry out
Gas sampling, this beam tube are generally made of polythene material.Beam tube is laid in goaf, and bad environments in goaf are adopted
Falling rocks easily pounds sampling beam tube in dead zone, causes sampling pipe damaged.Meanwhile falling rocks can also pound flat sampling beam tube, cause beam tube
Blocking, can not collect sample gas.Once sampling pipe is damaged, and since beam tube uses negative pressure taking gas, managing outer gas will be mixed into pipe,
Cause the sample gas of acquisition impure, meanwhile, falling rocks can also pound flat sampling beam tube, and beam tube is caused to block, and can not collect sample gas.Cause
The data inaccuracy of detection and analysis, can not react the gaseous environment that underground is really, the therefore " spontaneous combustion marked off according to these data
Three bands " are also inaccuracy.
Summary of the invention
To achieve the goals above, the present invention provides for coal mine gob gas sampling assembly and its user
Method.The device can work normally under the complex environment in goaf, will not be smashed or be pounded by falling rocks it is flat, and can be very convenient
Be attached and dismantle, ensure that the gas of acquisition is pure, the data accurate and effective of detection and analysis.
To achieve the goals above, the technical solution adopted by the present invention are as follows: including beam tube, beam tube is combined by several single tubes
And outside extrudes outer sheath composition, beam tube front end is provided with sampling protective device, and protective device includes single tube connector, dust-filtering
The end of device and protective case, single tube connects dust filter unit by single tube connector, is arranged between the single tube and dust filter unit
There is protective case, the protective case is that several metal tubes removably connect composition.
In order to further realize the technical program, can also use following technical scheme: the protective case is covered in single tube
Outside, protective case one end connect dust filter unit, single tube connector be located at the inside of protective case and setting on dust filter unit,
The end of single tube connects single tube connector.One end of the protective case connects dust filter unit, and the other end of protective case is arranged single
The end of pipe fitting, single tube is connect with single tube connector.The dust filter unit is pipe closed at one end, and is provided on the pipe
Several filter hole.The protective case is several steel pipes composition, and several steel pipes are inter-connected via a bolt joint.
The application method of gas sampling assembly for coal mine gob, the steps include:
The first step, first before goaf top plate first weighting, using sampling pipe degassing method observation goaf gas concentration point
Cloth lays sampling pipe from the lateral goaf of return air, sampling pipe is across goaf, and every one sampling probe of several meters of arrangements,
Acquire the gas in goaf；
Step 2: mathematical model is constructed by carrying out data analysis to the gas of acquisition, so that Preliminary division goes out goaf " certainly
Fire fire " three bands；
Step 3: the sampling steel pipe in the goaf that is laid in is buried after the first weighting of goaf, gas can not be acquired, at this time
Continue to sample using the multi-channel sampling steel pipe for the air return lane that is laid in, sampling pipe protective case removably connects, can be very convenient
Be attached and dismantle, after the first weighting of goaf, by that section of metal tube being buried from sampling metal tube on remove,
Sampling pipe other parts continue to sample, and sampling pipe is continued to move to the propulsion of working face, subsequent after the first weighting of goaf
Roof weighting in periodically, with the propulsion of working face, the sustainable progress of beam tube sampling can be in continual analysis goaf
Gas situation of change, and by building mathematical model, dynamically divide the range of goaf " three band of spontaneous combustion ".
The invention has the benefit that the accuracy of Tube Bundle Monitoring System analysis data has been effectively ensured in the present invention.It is adopting
Dead zone arrangement has the sampling beam tube of protective jacket, and protective case will not smash by the falling rocks in goaf, will not the outer gas of generator tube it is mixed
Enter the situation in pipe, to ensure that collected sample gas is not contaminated, effective always, and then Tube Bundle Monitoring System divides
The goaf gaseous environment data analysed are also true and reliable.Metal tube has the characteristics that tension, resists and pound, can be in goaf
It is worked normally under complex environment, will not be smashed or be pounded by falling rocks flat, while there is special connector at metal tube both ends, can be very
Easily it is attached and dismantles, it is easy to use, it both ensure that the gas of acquisition was pure in this way, the data also tested and analyzed are accurate
Effectively.The present invention also has the advantages that structure is simple, compact and low in cost.
