Vatengesi veMigodhi yeMataira muChina: Mhinduro Dzinogarika kubva kuFekitori Inotungamira

,

Kutarisira zvakanaka masuwa emugodhi kwakakosha kuindasitiri yemigodhi yepasi rose, kunyanya kana mabasa emigodhi ari kuwedzera. Makambani emigodhi pasi rese, kusanganisira ari muChina, ari kutarisana nedambudziko guru rekubata nekushandisa masuwa nenzira ine musoro. Chinyorwa chino chichaongorora mapurojekiti maviri anozivikanwa emasuwa emugodhi: chirongwa chemasuwa emugodhi weZambia nechirongwa chemasuwa emugodhi weMadagascar, ese akatangwa muna 2019. Mapurojekiti aya haangoratidzi mhinduro dzakasiyana dzehunyanzvi chete asiwo anoratidza kuzvipira kwenyika dzavo mukusimudzira chikamu chemigodhi. Sezvo vatengesi nemafekitori ekuChina vachiramba vachiwedzera hunyanzvi mukutarisira masuwa, vanoita basa rakakosha mukutsigira kuedza kwepasi rose kwekuchengetedza nharaunda mumigodhi.

    Ruzivo rweChigadzirwa

    1. Chirongwa cheMigodhi yeZambia

    Chirongwa chekuchera matope emumigodhi muZambia chinonyanya kusanganisira kushandiswa kwemapaipi esimbi yekabhoni nemaflange esimbi zvichienderana nemaitiro eAPI 5L GR.B neASME A105. Chinangwa chikuru chechirongwa ichi ndechekutarisira nekufambisa matope emumigodhi zvinobudirira kuderedza kukanganisa kwezvakatipoteredza uye kuwedzera kudzoreredzwa kwezviwanikwa.

    Muchirongwa ichi, mapaipi esimbi yekabhoni anoshandiswa zvakanyanya musystem yekutumira tailings. API 5L GR.B standard inovimbisa kugara kwenguva refu uye kuvimbika kwemapaipi ari mumamiriro ekumanikidzwa kwakanyanya uye tembiricha yepamusoro, nepo ASME A105 standard ichivimbisa mhando yemaflanges uye kuchengetedzeka kwekubatanidza. Kusarudzwa kwezvinhu izvi hakungogadzirisi mashandiro ese esystem, asiwo kunoderedza mari yekugadzirisa uye kuwedzera hupenyu hwebasa.

    Pamusoro pezvo, chirongwa cheZambia chinotarisawo pakurapa miswe isina njodzi kune nharaunda. Nekushandisa tekinoroji yepamusoro yekugadzirisa miswe, timu yechirongwa ichi inogona kuderedza zvinobudirira kukanganisa miswe yakapoteredza uye kuona kuti mabasa ekuchera migodhi anogara kwenguva refu. Kubudirira kwechirongwa ichi kwakapa rutsigiro rwakasimba mukusimudzira indasitiri yemigodhi yeZambia, uye kwakapawo ruzivo rwakakosha mukutarisira miswe yakaomeswa mune dzimwe nyika.

    Zvinhu: Pombi yesimbi yekabhoni ine flange yesimbi
    Mitemo: API 5L GR.B & ASME A105
    Chirongwa chekuchera migodhi muZambia
    2. Chirongwa cheMigodhi yeMadagascar

    Zvichienzaniswa neprojekti yeZambia, projekti yekuchera matope muMadagascar yakasiyana pakusarudza tekinoroji. Projekti iyi inoshandisa musanganiswa wemapaipi esimbi yekabhoni neHDPE (high-density polyethylene), maflange eHDPE nemaflange esimbi, zvinoenderana nezvinodiwa neAPI 5L GR.B, ISO 4427 PE 100 uye ASME 16.5 A105. Musanganiswa uyu wezvinhu zvakawanda unovandudza zvakanyanya kuramba ngura uye simba resystem yekutakura matope.

    Kushandiswa kwemapaipi eHDPE kunoita kuti chirongwa cheMadagascar chikwanise kubata zvakanaka miswe inoora. Zvinhu zveHDPE zvine simba guru rekudzivirira makemikari uye resistance yeUV, izvo zvinogona kuwedzera hupenyu hwemapaipi. Pamusoro pezvo, kushandiswa kwemaflange eHDPE kunovandudzawo kuvharwa kwekubatana uye kunoderedza njodzi yekubuda kwemvura.

    Chimwe chinhu chinokosha pachirongwa cheMadagascar ndechekusimbisa kwachinoita kuchengetedzwa kwezvakatipoteredza. Munguva yekugadzira nekushandisa, timu yechirongwa ichi yakafungisisa zvizere nezvemhedzisiro yetsvina pazvakatipoteredza uye yakatora matanho akatevedzana ekuderedza kusvibiswa kwetsvina kumasosi emvura nevhu. Izvi hazvingoteveri chete mitemo yepasi rose yezvakatipoteredza, asiwo zvinobatsira mukusimudzira nharaunda dzemuno.

    Mapurojekiti ekuchera matope emumigodhi muZambia neMadagascar anoratidza mhinduro dzakasiyana dzehunyanzvi uye nzira dzekutarisira, zvichiratidza kushanda nesimba kwenyika dzavo mukusimudzira kuchera matombo nenzira inochengetedza nharaunda. Nekushandisa zvinhu zvemhando yepamusoro uye matekinoroji epamusoro, mapurojekiti maviri aya haangogadzirise chete kushanda zvakanaka kwekutarisira matope emumigodhi, asiwo anopa mipiro yakanaka mukuchengetedzwa kwezvakatipoteredza.

    Chirongwa chekuchera slurry muMadagascar
    Kuiswa kwepombi dzeMadagascar
    Mune ramangwana, sezvo nyika icharamba ichinyanya kutarisisa budiriro inochengetedza nharaunda, indasitiri yemigodhi icharamba ichitsvaga nzira dzekugadzirisa masukisi emumba dzinochengetedza nharaunda uye dzinoshanda. Ruzivo rwakabudirira rweZambia neMadagascar ruchapa mukana kune dzimwe nyika uye ruchasimudzira budiriro inochengetedza indasitiri yemigodhi yepasi rose.

    Ndezvipi zviyero zvemapaipi zvinoshandiswa muZambia Mining Tailings Project?
    Chirongwa cheZambia chinoshandisa zvikuru mapaipi esimbi yekabhoni nemaflange esimbi zvinoenderana nezvinodiwa nemaindasitiri zveAPI 5L GR.B neASME A105 kuti ive nechokwadi chekuti zvinhu zvakachengeteka uye zvinogara kwenguva refu kana zvaoma.
    Kusarudzwa kwezvinhu zvepombi kunosiyana sei muchirongwa cheMadagascar?
    Kusiyana nemapaipi esimbi yakasanganiswa nekabhoni muZambia, chirongwa cheMadagascar chinoshandisa musanganiswa wemapaipi esimbi yakasanganiswa nekabhoni neHDPE (high-density polyethylene), pamwe chete nemaflange eHDPE nemaflange esimbi.
    Ndezvipi zvakanakira kushandisa mapaipi eHDPE pakutakura miswe?
    HDPE inopa simba rekudzivirira makemikari neUV, izvo zvinoshanda zvikuru pakutakura tsvina yemugodhi inoparadza, kuderedza njodzi dzekubuda kwemvura, uye kuwedzera hupenyu hwepombi.
    Ndezvipi zvinodiwa zvepasi rose zvinosangana nezvikamu zvepurojekiti yeMadagascar?
    Zvikamu zvepombi muchirongwa cheMadagascar zvinotevedzera API 5L GR.B, ISO 4427 PE 100, uye ASME 16.5 A105.
    Mapurojekiti aya anobatsira sei pakuchengetedzwa kwezvakatipoteredza?
    Mapurojekiti ese ari maviri anoshandisa zvinhu zvepamusoro-soro uye matekinoroji epamusoro ekugadzirisa tsvina yemumba kudzivirira kusvibiswa kwevhu nemvura yemuno, zvichiita kuti mabasa ekuchera migodhi arambe achienderera mberi.
