Hom twg los nrhiav cov dej nqus dej hauv av?

Yuav kom nrhiav tau cov av zoo thiab txhawm rau paub qhov tob, qhov ntau thiab cov dej zoo, ntau cov hom kev kawm yuav tsum raug siv, thiab thaj chaw yuav tsum raug kuaj xyuas thiab tshawb xyuas kom paub txog hydrologic thiab geologic features uas tseem ceeb rau kev npaj thiab kev tswj ntawm qhov chaw.



Txij ntawm kev ntsuas, hom, qhov loj thiab qhov zoo ntawm cov khoom aquifer raug deduced thiab teev, los yog saib tsam tsuas yog presumed, tab sis nrog ib tug high probability.


Nws muaj ob lub ntsiab ntawm txoj kev, uas yog siv qee zaum ua tiav:

Prton Magnetometer

a) Kev ntsuas ntawm hluav taws xob resistivity siv ncaj qha tam sim no.


Qhov no yog txoj kev siv ntau tshaj plaws raws li nws tau haum rau ntau tshaj plaws ntawm cov xwm txheej.

Nws muaj hauv kev xa ncaj qha mus rau hauv ib qho chaw geological ntawm qhov chaw uas tau muab (50 mus rau 400 volts nyob ntawm nws cov resistivity - conductivity) siv ob lub electrodes (A thiab B).


Muaj ob peb tau ntawm electrode arrays (Wenner, Schlumberger, 4 terminals, thiab lwm yam).


Qhov chaw tshawb xyuas yuav tsum tsis txhob loj heev thiab yuav tsum yog lub tiaj tiaj thiab dawb ntawm cov tuam tsev uas yuav ua rau cuam tshuam thiab yuav ua kom tsis muaj AB cov kab ntawm qhov yuav tsum tau ntev (tshaj 300m).


b) Hom kev ntsuas qhov teebmeem no qhov teeb meem ntawm kev sib nqus

Yooj yim rau kev siv, xws li VLF txoj kev, cov tswv yim no ntsuas cov kev teeb tsa electromagnetic vim muaj kev sib nqus induction phenomena. Lawv tsis xav tau kev sib txuas lus nrog rau hauv av thiab yog li tsis muaj electrodes. Lawv ua tau los ntsuas cov av qhov reactivity rau kev ua kom mob siab electromagnetic. Txawm li cas los xij, lawv tsis tuaj yeem siv rau txhua hom thaj av lossis cov chaw lim dej muaj tshaj li 20 meters los yog tsawg dua. Nkawd siv nkawd hloov tsis tau.
