Description
Technical field
The present invention relates to a kind of transmission channel wave survey method for mine, specifically a kind of ground for highly gassy mine
Shake transmission channel wave survey method.
Background technique
Along with the sustainable development of coal industry, mine safety problem also very severe, as coal and gas prominent, mine are prominent
Water etc. all seriously affects the life security problem of mine worker.East mining area increases with mining depth, accounts for national coal resources
Reserves are more than that 2/3 central and west regions are influenced by unfavorable factors such as complicated landform, loess covering, exposed bedrocks, ground three
Dimension earthquake finds out that drop≤10m tomography is restricted；In multiple seam area, on superficial part, the exploitation of group coal and multilayer are adopted
The influence of dead zone and subsidence, Three Dimensional Ground seismic prospecting no longer have seismic prospecting condition.Therefore, conducting shaft earthquake
Detection study is the great demand that country ensures that safety of coal mines efficiently produces.
The highly gassy mine in China is large number of at present, when highly gassy mine stope carries out transmission exploration, by
In in order to improve digging efficiency, therefore the width of the working face modernized is larger (width is typically larger than 200~300m), and existing
Hammering focus propagation distance it is extremely limited (usually less than 60m), thus be unable to satisfy to working face transmission exploration require.Separately
Although outer existing dynamite source is able to satisfy the requirement of propagation distance, but since it needs to add specific high-tension apparatus, and
And need to carry out the construction of corresponding explosion, to will affect the normal construction efficiency of working face；Secondly, working in highly gassy mine
Face, due to there are many gas-discharging holes, gas in extraction working face, using dynamite source due to after explosive initiation not
Controllability can impact these gas-discharging holes and even destroy, and influence the pump drainage of gas；Finally, such as in highly gassy mine
Working face uses explosive as focus, and there are biggish security risk, easily generation gas explosions, to life security and property safety
It brings about great losses.Innovation is carried out for this to the focus of highly gassy mine stope transmission channel wave survey based on the above situation
The problem of industry current urgent need to resolve.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of earthquakes for highly gassy mine to transmit slot wave
Exploitation method, using CO2Big gun not only can guarantee to vibration energy needed for stope transmission exploration, simultaneously as focus
Have the advantages that low pressure detonation, focus orientation, energy-controllable and reusable, to be suitable for highly gassy mine back production work
Make the transmission channel wave survey in face.
To achieve the goals above, the technical solution adopted by the present invention is that：A kind of earthquake transmission for highly gassy mine

B, it helps equidistantly to lay multiple CO side by side to stope in the track lane of stope side2Gun excitation
Drilling, by multiple CO2Big gun one-to-one correspondence is laid in each CO2In gun excitation drilling, then by each CO2The detonating cord of big gun is drawn
To drilling orifice；
C, it is helped in the belt lane of the stope other side, equidistantly lays multiple wave detectors, multiple wave detectors side by side
It is connect by connection main line with acquisition base station and acquisition host, wave detector, acquisition base station and acquisition host is made to form back production work
Make face SEISMIC CHANNEL WAVE METHOD transmission exploration system；
D, by the CO in step B2Big gun triggers box by detonating cord and signal and is connected in parallel on low pressure initiator, and signal triggers box
It is connect with acquisition host；
E, acquisition host is opened, distance is connected by low pressure initiator and cuts the nearest or farthest CO of eye2Big gun is as the first CO2
Big gun, along CO2Gun excitation drills to actual mining surface launching one-shot energy, and synchronous signal triggering box feeds back to acquisition host touching
It signals, makes acquisition host start to receive the SEISMIC CHANNEL WAVE METHOD signal data that wave detector transmits, acquisition host is recorded；Then low
Press initiator connection and the first CO2The adjacent CO of big gun2Big gun, along CO2Gun excitation drills to actual mining surface launching one-shot energy
Amount, acquisition host are recorded again, such sequential transmission, until each CO2After big gun completes transmitting, collecting work is completed；
F, collected multiple vibration slot wave signal is passed to computer, computer combination field geology money by acquisition host
Material carries out comprehensive analysis, is finally completed the process of stope transmission channel wave survey.
Further, the multiple CO2The distance between gun excitation drilling is 10 meters.
Further, the distance between multiple wave detectors are 10 meters in the step D.
Further, the CO2Big gun is CO2The vibration big gun excited in gas phase pressure break pipe.
Compared with prior art, the present invention uses CO2Big gun is as focus, due to CO2Big gun has low pressure detonation, orientation installation
Detonation, energy-controllable and reusable feature, since its low pressure is detonated, and its detonation mode is to pass through launching shock energy
Amount shakes coal and rock, to will not cause the possibility of gas explosion, additionally, due to CO2The directional transmissions controllability of big gun, thus
It gas drilling will not be impacted to around in its launching shock energy, to guarantee the normal drawing-off gas of gas drilling；And
And CO2The impact energy of big gun transmitting is able to satisfy the requirement of transmission stope, in addition CO2Big gun has been used as under mine at present to coal
One of layer antireflective tool of working face pressure break, therefore use CO2Big gun is surveyed as the transmission slot wave of highly gassy mine stope
The focus mode of spy increases focus equipment without additional, its working principle is that becoming gaseous CO from liquid by directional transmissions2,
Expand anti-reflection to the original crack in coal and rock inside by its impact force or carry out pressure break and generate new crack, thus just
It is extracted in the intracorporal gas of coal petrography, the present invention exactly utilizes CO2Coal and rock is impacted after big gun transmitting, impact energy
Meeting is measured so that coal and rock generates slot wave signal；Based on These characteristics, therefore the present invention is suitable for highly gassy mine actual mining
The transmission channel wave survey in face.
