Tuam Tshoj Cov Neeg Muab Khoom ntawm Cov Kav Dej Mining Tailings: Cov Kev daws teeb meem ruaj khov los ntawm Lub Hoobkas Ua Lag Luam

,

Kev tswj hwm cov tailings zoo yog qhov tseem ceeb rau kev lag luam mining thoob ntiaj teb, tshwj xeeb tshaj yog thaum muaj kev nce ntxiv ntawm cov haujlwm mining. Cov tuam txhab mining thoob ntiaj teb, suav nrog cov neeg nyob hauv Suav teb, tab tom ntsib teeb meem loj ntawm kev tuav thiab siv cov tailings kom raug. Tsab xov xwm no yuav tshawb nrhiav ob qhov project mining tailings tseem ceeb: qhov project Zambia mining tailings thiab qhov project Madagascar mining tailings, ob qho tib si tau pib xyoo 2019. Cov project no tsis yog tsuas yog qhia txog ntau yam kev daws teeb meem xwb tab sis kuj qhia txog kev cog lus ntawm lawv lub teb chaws rau kev txhim kho kev lag luam mining. Raws li cov neeg muab khoom thiab cov chaw tsim khoom hauv Suav teb txuas ntxiv tsim kho tshiab hauv kev tswj hwm tailings, lawv ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev siv zog thoob ntiaj teb rau kev ruaj khov ib puag ncig hauv kev mining.

    Cov Lus Qhia Txog Khoom

    1. Zambia Mining Tailings Project

    Qhov project mining tailings hauv Zambia feem ntau yog siv cov kav hlau carbon thiab cov flanges hlau raws li API 5L GR.B thiab ASME A105 cov qauv. Lub hom phiaj tseem ceeb ntawm qhov project no yog los tswj thiab thauj cov tailings mining kom zoo kom txo tau kev cuam tshuam rau ib puag ncig thiab ua kom cov peev txheej rov qab zoo dua.

    Hauv qhov project no, cov kav dej carbon steel tau siv dav hauv cov txheej txheem thauj cov tailings. API 5L GR.B tus qauv ua kom cov kav dej ruaj khov thiab ntseeg tau nyob rau hauv qhov kub siab thiab kub siab, thaum ASME A105 tus qauv ua kom zoo ntawm cov flanges thiab kev nyab xeeb ntawm kev sib txuas. Kev xaiv cov ntaub ntawv no tsis yog tsuas yog txhim kho kev ua haujlwm tag nrho ntawm lub system, tab sis kuj txo cov nqi kho thiab ua kom lub neej ua haujlwm ntev.

    Ntxiv rau qhov ntawd, Zambia qhov project kuj tsom mus rau kev kho cov tailings uas tsis ua rau ib puag ncig puas tsuaj. Los ntawm kev siv cov thev naus laus zis kho tailings siab heev, pab pawg project tuaj yeem txo qhov cuam tshuam ntawm tailings rau ib puag ncig thiab xyuas kom meej tias muaj kev ruaj khov ntawm cov haujlwm mining. Kev ua tiav ntawm qhov project no tau muab kev txhawb nqa zoo rau kev txhim kho Zambia txoj kev lag luam mining, thiab kuj tau muab kev paub zoo rau kev tswj hwm cov tailings mining hauv lwm lub tebchaws.

    Cov Lus Qhia Txog Qhov Project
    Qhov project: Zambia mining project
    Cov Khoom Siv: Cov yeeb nkab carbon nrog cov hlau flange
    Cov Qauv: API 5L GR.B & ASME A105
    Zambia mining project
    2. Qhov project Madagascar Mining Tailings

    Piv rau qhov project Zambia, qhov project mining tailings hauv Madagascar txawv ntawm kev xaiv thev naus laus zis. Qhov project siv kev sib xyaw ua ke ntawm cov hlau carbon thiab HDPE (high-density polyethylene) kav dej, HDPE flanges thiab steel flanges, uas ua raws li API 5L GR.B, ISO 4427 PE 100 thiab ASME 16.5 A105 cov qauv. Qhov kev sib xyaw ua ke ntawm ntau yam khoom no ua rau muaj kev tiv thaiv corrosion thiab lub zog ntawm cov tailings conveying system.

    Kev siv cov kav dej HDPE ua rau qhov project Madagascar ua tau zoo hauv kev tswj cov tailings corrosive. Cov ntaub ntawv HDPE muaj kev tiv thaiv tshuaj lom neeg zoo heev thiab tiv thaiv UV, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov kav dej ntev dua. Tsis tas li ntawd, kev siv cov flanges HDPE kuj tseem txhim kho kev sib khi ntawm qhov txuas thiab txo qhov kev pheej hmoo ntawm kev xau.

    Lwm qhov tseem ceeb ntawm qhov project Madagascar yog nws qhov kev tsom mus rau kev tiv thaiv ib puag ncig. Thaum lub sijhawm tsim thiab kev siv, pab pawg project tau xav txog qhov cuam tshuam ntawm cov khib nyiab rau ib puag ncig thiab tau siv ntau yam kev ntsuas los txo qhov kev ua qias tuaj ntawm cov khib nyiab rau cov dej thiab av. Qhov no tsis yog ua raws li cov qauv ib puag ncig thoob ntiaj teb xwb, tab sis kuj pab txhawb rau kev txhim kho kom ruaj khov ntawm cov zej zog hauv zos.

    Cov haujlwm khawb av hauv Zambia thiab Madagascar qhia txog ntau yam kev daws teeb meem thiab cov tswv yim tswj hwm, uas qhia txog kev siv zog ntawm lawv lub tebchaws hauv kev txhim kho kev khawb av kom ruaj khov. Los ntawm kev siv cov ntaub ntawv zoo thiab cov thev naus laus zis siab heev, ob qhov haujlwm tsis yog tsuas yog txhim kho kev ua haujlwm ntawm kev tswj hwm cov av xwb, tab sis kuj ua rau muaj kev pab zoo rau kev tiv thaiv ib puag ncig.
