Description
Technical field
After the invention belongs to fissure zone gas density to investigate technical field, more particularly to a kind of return airway high position drill site is closed
The method for observing single hole gas density.
Background technology
High-order drill site gas pumping in high-order drill site to goaf really by constructing strike long drill extraction crack
A large amount of high concentration gas with accumulation, gush out so as to reduce the gas in goaf to upper corner.Due to high-order drill site closing after,
Its single hole concentration can not be investigated, so as to not can determine that fissure zone gas enrichment region height and leave the body of band；Conventional true
When determining fissure zone height, using water flowing fractured zone and empirical value as etc. reference, these methods can not intuitively show place's fissure zone
Height and distributional pattern.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of return airway high position drill site closed rear observation single hole gas density
Method, with overcome high-order drill site even take out construction it is closed after, single hole change in concentration that can not be drilled to it is investigated, so as to can not adopt
The problems such as by the use of variation ofgas density data as the distributional pattern of the height of analysis fissure zone and fissure zone.
Technical solution of the present invention is as follows：
A kind of return airway high position drill site it is closed after observation single hole concentration method, including high-order drill site, drilling, gas pipe,
Beam tube, negative pressure sampler and interference of light gas detector, after the drilling and sealing of high-order drill site terminates, utilize the single-core tube in beam tube
Each drilling is intubated, then beam tube is guided under high-order drill site in mouth return airway, the interference of light is connected to by negative pressure sampler
Gas detector observes gas density.
The fiber tube that buries that single-core tube is even taken out to each drilling carries out brokenly osculum and inserts and number, and cement or agate are used after insertion
Beautiful scattered be intubated around seals.
After high-order drill site is suitable for reading, middle and lower mouth has been constructed three it is closed after, single-core tube is connected to water-inlet-proof by rubber tube
Device one end, other end connection negative pressure sampler air entry；Open negative pressure sampler and the other end is connected to optical interference watt inspection
Device inlet end, after 2~10 minutes to be sampled, interference of light gas detector change in concentration is observed, after change in concentration is stable, for most
Whole single hole gas density, then observes the gas density each to drill one by one.
The negative pressure sampler, i.e. high negative pressure gas sampler.
The optical interference watt inspection device, refer exclusively to " interference of light gas detector ".
The waterproof device, refer to any to prevent（Prevent）Water enters beam tube（Single-core tube）With the device of rubber tube
Or device.
It is described to bury fiber tube, refer to the rubber tube that iron wire is wound with inside it, play connection function, some places of underground coal mine use
It is inconvenient to be connected between hard gas pipe and drilling, then using burying fiber tube connection drilling and hard gas pipe.
The company takes out, and refers to the meaning of " connecting gas extraction ".
It is described closed, can be arbitrary closed structure.
Following flow is referred to during practical operation：After high-order drilling holes at the drilling yard sealing of hole terminates, it is connected to point using fiber tube is buried
Flow on device, then gas pipe be connected to by current divider, using the single-core tube in beam tube each drilling is even taken out bury fiber tube carry out brokenly it is small
Mouth is inserted and numbered, and is dissipated after insertion using cement or Mary and is carried out intubation periphery seal, beam tube is guided under high-order drill site afterwards
In mouth return airway.Waterproof device can be further used, i.e., after high-order drill site is closed, beam tube is connected by waterproof device
To negative pressure sampler, beam tube sampling is carried out, and interference of light gas detector is connected in negative pressure sampler outlet side, observation gas is dense
Degree change.
The inventive method is simple, reliable, and beam tube intubation observes one borehole variation ofgas density in high-order drill site, effectively
Solve High Position Drilling it is closed after, can not variation ofgas density be joined during back production to the one borehole in high-order drill site
Number is collected, so as to develop shape using single hole variation ofgas density data to analyze the height of fissure zone gas enrichment region and fissure zone
State, reduce and investigate fissure zone cost and investigate accuracy, be easy to grasp general principle in actual mechanical process.

Fig. 2 is a-quadrant enlarged diagram in Fig. 1；
Fig. 3 is B area enlarged diagram in Fig. 1.
Embodiment
As shown in Figures 1 to 3, a kind of method of observation single hole gas density after return airway high position drill site is closed, including a high position
Drill site 11, drilling 1, bury fiber tube 2, current divider 3, gas pipe 6 and beam tube 4, the high-order sealing of hole of 11 internal drilling of drill site 1 terminate after using burying
Fiber tube 2 is connected on current divider 3, then is connected to gas pipe 6 by current divider 3, and each drilling 1 is connected using the single-core tube 5 in beam tube 4
Burying of taking out carries out brokenly osculum and inserts and number on fiber tube 2, dissipate to be intubated using cement or Mary after insertion and around seal, afterwards
Beam tube 4 is guided in high-order 11 lower mouthfuls of return airways of drill site 13.
Further, waterproof device 8 can be introduced.After inclined gallery 12 are suitable for reading, middle and lower mouth has been constructed after three closed 14, carry
High methane pipe negative pressure, one by one check beam tube 4 in single-core tube 5 whether air-breathing（Air-breathing then represents to be intubated successfully, on the contrary then water blockoff or its
His reason）.When investigating single hole gas density, single-core tube 5 is connected to the one end of waterproof device 8, other end connection by rubber tube 7
The air entry of negative pressure sampler 9；Negative pressure sampler 9 is opened, checks the whether normal outlet in outlet side（Outlet then represents that sampling is normal,
It is on the contrary then water blockoff or other situations occur）, after normal outlet, the inlet end of interference of light gas detector 10 is directly connected to, waits to adopt
The change in concentration of observation interference of light gas detector 10, it is final single hole gas after change in concentration is stable after sample 2~10 minutes
Concentration, and observe drilling gas change in concentration one by one daily.By drilling 1 and goaf discrepancy in elevation relation, analyze the different discrepancy in elevation and
It is flat away from variation ofgas density, determine that fissure zone gas is enriched with zone position.The method is solved after high-order drill site 11 is closed not
Single hole variation ofgas density can be investigated, this method is simple, convenient, greatly improves the capacity gauge of underlying parameter.
