Imayini yegolide ye-alluvial ibe yingxenye ebalulekile ye-industrial yokumbiwa kwemigodi eMongolia, ibe nomthelela ekuthuthukisweni komnotho walesi sizwe. Le ndatshana ihlola izindlela ezihlukene ezisetshenziswe ekumbiwa kwegolide ye-alluvial eMongolia, igqamisa ukubaluleka kwazo emlandweni nasezishintshweni zesimanje.
Ukumba igolide eliwaka kubhekisela enqubweni yokukhipha igolide ezindaweni zokugcina emanzini, ezaziwa nangokuthi izindawo zokugcina ezilwaziyo. Lezi zindawo zikhula ngokukhathazeka nokuhlubuka kwamatshe aphethe igolide, alandelwa ukuhanjiswa kwamanzi bese efakwa ezindaweni zemifula nasemahlathini aphakeme.
Ngokwesikhathi, ukumba igolide le-alluvial eMongolia kuqale amakhulu eminyaka, nezindlela zendabuko zidluliselwa ezizukulwaneni. Lezi zindlela zishintshile ngokuhamba kwesikhathi, zathinteka yintuthuko yezobuchwepheshe nezinto ezithinta imvelo.
Iziphakamiso zezesekeli zokuqothula igolide ezivamile eMongolia zazivame ukuba kakhulu ngesandla futhi zisebenza kakhulu. Lezi zindlela zifaka:
Ngokuthuthuka kwezobuchwepheshe, izindlela zanamuhla zokumbiwa kwegolide ezinambuzane sezakhiwe eMongolia, kuthuthukiswa ukusebenza kahle kanye nokukhiqiza. Lezi zindlela zifaka phakathi:
Ukumba kwe-hydraulic kuhilela ukusebenzisa amathuluzi amanzi aphakeme ukuze kukhishwe izinto zokwakha nezimuncagazi, kuvumela ukuthi igolide ikhakhelwe kwi-slurry eyenziwe.
– Ukuze kube ne-efficiency ephezulu nokwanele.
– Ikhono lokucubungula ivolumu enkulu yamathe ngokushesha.
– Amathuba okuba nomthelela omkhulu kwemvelo.
– Icela izinsiza zamanzi ezinkulu.
Ukukhukhuma kusetshenziswa imishini yokumbiwa ethokozisayo ukuze kuhlwanyelwe i-sediment ezisekelweni zemifula, kuhlukaniswe igolide emathanjeni.
– Isebenza kahle ekukhipheni igolide ezindaweni ezisemanzini.
– Ingak covering izindawo ezibanzi.
– Izindleko zokusebenza eziphezulu.
– Izinkinga ezihambisana nokuphazamiseka kwemfula.
I-trommel iyisivivane esiphindaphindayo esiyisikhumbuzo esisetshenziswa ukukhipha igolide kwi-sediment. Ehlangene ne-wash plant, ikhulisa amazinga okubuyisela igolide.
– Ukuhlukaniswa okusebenzayo kwegolide ezinqwabeni ezinkulu zempheme.
– Iphathekile futhi ilungele izindawo ezihlukene zokumbiwa.
- Izindleko zokuqala zingaba phezulu.
– Kudinga ukuhambisana okuvamile.
Ukushintsha kokuya kwezindlela zanamuhla kulethe ukukhathazeka okwandisiwe mayelana nomthelela wokuphila kwemvelo kanye nokuhambisana nemithetho. Izinto eziyisisekelo okufanele zicatshangelwe zifaka phakathi:
Ukukhukula igolide ye-alluvial eMongolia sekuye kwashintsha kusukela ezindleleni zendabuko, ezisebenza ngezandla, zaya ezindleleni ezithuthukisiwe, ezenzakalelayo. Ngesikhathi ezindlela zanamuhla zinikeza ukusebenza kahle okwandisiwe nokukhipha, ziphinde zifake izinselelo zemvelo eziyidingayo ukuphathwa ngokucophelela. Ukuhlanganisa izinzuzo zezimali nokuphatha kwemvelo kuqhubeka kuba yinsika ebalulekile embonini yokukhukula eMongolia.
Ngokwazi ukuqonda umongo w историю kanye nokuthuthuka kwezobuchwepheshe ekumbaleni kwegolide eliphakeme, ababambiqhaza bangakwenza izinqumo ezinolwazi ezisekela ukuthuthukiswa okuqhubekayo eMongolia.
