Cov chav kawm txaus ntshai yog cov xwm txheej ib puag ncig cuam tshuam ntawm cov khib nyiab, uas yog txiav txim siab los ntawm cov teeb meem ntawm kev cuam tshuam kev cuam tshuam ib puag ncig ib puag ncig. Txhua lub chaw lag luam thiab cov koom haum, vim tias cov tshuaj tsis pom tseeb tshwm sim, yuav tsum faib cov khoom pov tseg raws li lawv qhov kev nyab xeeb hauv kev nruj raws li txoj cai ib puag ncig.
Tsim nyog
- - Daim ntawv teev cov khoom pov tseg;
- - cov ntxhuav thiab cov laij lej los txiav txim siab chav kawm phom sij.
Cov Lus Qhia
Kauj ruam 1
Txhawm rau faib cov khib nyiab pov tseg rau hauv chav kawm phom sij uas yog siv cov txheej txheem xam, nrhiav qhov ntsuas (K) - qhov ntsuas ntawm qhov ntsuas ntawm qhov muaj kev phom sij ntawm cov khib nyiab rau OPS (ib puag ncig). Yog tias cov pov tseg muaj ntau yam tshuaj, suav nws cov txiaj ntsig yog qhov suav ntawm qhov ntsuas phom sij ntawm cov tshuaj (Ki). Yog li ntawd, ua ntej tshaj plaws, tsim: a) cov npe ntawm cov pov tseg (muaj pes tsawg leeg); b) cov lus qhia ntau npaum li cas ntawm txhua feem. Raws li txoj cai, cov khoom pov tseg ntawm cov pov tseg yog txiav txim siab los ntawm cov khoom sib xyaw ntawm cov khoom noj, noj rau hauv suav cov kev hloov pauv uas tshwm sim nrog nws hauv cov txheej txheem thev naus laus zis, lossis raws cov txiaj ntsig ntawm kev tshawb nrhiav tshuaj lom neeg.

Tam sim no xam qhov ntsuas phom sij rau txhua qhov pov tseg uas siv cov qauv: Ki = Ci / Wi (Ci yog qhov khoom siv ntawm cov khoom pov tseg, thiab Wi yog qhov sib npaug coefficient rau OPS). Txhawm rau txiav txim siab qhov coefficient (Wi) hauv Lub Txheej Txheem ntawm Ministry of Natural Resources "Ntawm kev pom zoo ntawm cov qauv rau kev faib cov khoom pov tseg raws li qhov muaj kev phom sij rau ib puag ncig" hnub tim 2001-15-06, muaj lub rooj tshwj xeeb (saib daim duab) Cov

Yog tias koj tau tsim cov qib ntawm kev nyab xeeb ntawm cov khoom pov tseg hauv ib puag ncig ntuj, lawv tuaj yeem siv los laij cov ntsuas kev nyab xeeb ntawm cov khoom sib xyaw pov tseg rau OPS (Xi). Qhov no yog ua los ntawm kev faib tawm cov lej ntawm cov ntsiab lus ntawm tag nrho cov ntsuas los ntawm tus xov tooj ntawm cov tsis. Wi coefficient tuaj yeem xam tau siv ib qho ntawm ntau cov qauv (txuas:

Cov txheej txheem (Wi) saib hauv lub rooj (saib daim duab). Nov yog sau cov khoom pov tseg feem ntau uas tuaj yeem tsim kev puas tsuaj rau OPS
Kauj ruam 5
Tom qab koj tau suav qhov ntsuas txaus ntshai ntawm ib qho zuj zus ntawm cov khoom sib txawv ntawm cov pov tseg Ki, xam K ntaus nqi ua cov lej ntawm cov ntsuas ntawm cov feem ntawm cov feem (K = K1 + K2 +… + Kn).
Kauj Ruam 6
Tam sim no laij cov chav kawm txaus ntshai ntawm qhov pov tseg rau thaj chaw ib puag ncig raws li lub rooj (saib daim duab). Yog tias cov khib nyiab poob rau hauv chav ceeb toom thib tsib, nws chav kawm yuav tsum paub tseeb los ntawm kev sim. Txwv tsis pub, koj yuav tsum tau tsim nyog cov chav kawm phom sij li 4

Txhawm rau txiav txim siab cov chav kawm phom sij sim, tiv toj lub chaw kuaj ntshav kuaj mob tshwj xeeb rau lub hom phiaj no.
