Kev tshawb nrhiav ntau yam ntawm cov cuab yeej ntsuas hlau hauv kev ua lag luam feem ntau yog raws li hauv qab no:
① Lub ntsuas me me ntawm tes tuav yog 1 ~ 40cm sib sib zog nqus, uas yog siv rau qhov chaw luv luv kom raug thiab tshuaj xyuas kev ruaj ntseg.
② Lub tes tuav sojntsuam disc underground hlau ntes yog 1 ~ 2m sib sib zog nqus, uas yog siv rau sab nraum zoov cov khoom muaj nqis tshawb nrhiav, engineering tshawb nrhiav thiab lwm yam haujlwm. Lub tshuab nrog synchronous ntau zaus thev naus laus zis tuaj yeem tshawb nrhiav kub thiab nyiaj hniav nyiaj hniav kub ntawm cov ntug hiav txwv dej siab.
③ Pulse type metal detector yog siv los lim cov khoom me me thiab tshawb nrhiav cov khoom loj hauv av hauv cov ntaub pua plag. Qhov ntsuas qhov tob tuaj yeem ncav cuag 3-4 meters. Nyob rau hauv txhua hom hlau ntes, qhov loj ntawm cov khoom siv hlau txiav txim siab qhov tob ntawm kev tshawb nrhiav. Piv txwv li, qhov ntev tshaj plaws siv tes tuav sojntsuam disk hlau ntes, tooj liab npib kaum ob peb centimeters, qhov loj dua cov khoom, lub teeb liab muaj zog dua, qhov tob zoo dua. Raws li qhov ua tau zoo sib txawv ntawm qhov siab thiab qis kawg, qhov txwv qhov tob yog nyob rau hauv thaj tsam ntawm 1-2 meters.
