Ukusebenza okuvelele komshini wokuhlunga we-hydraulic ozenzakalelayo ongu-630 ozimele wensimbi engagqwali enqubweni yokukhipha amanzi emzimbeni embonini yezimayini.

Isizinda samakhasimende
Ibhizinisi elikhulu lezimayini zethusi eChile selihlale libhekene nenkinga yokuphelelwa amanzi emzimbeni kwezindawo ezisele. Indawo enosawoti omningi kanye nomswakama ophezulu endaweni yezimayini ibangele ukugqwala okukhulu kwemishini yokuhlunga yensimbi yekhabhoni yendabuko, okudinga ukulungiswa nokuvalwa njalo ezinyangeni ezintathu ngokwesilinganiso. Ngesikhathi esifanayo, imishini ezenzakalelayo esebenza ngesandla inokusebenza okuphansi, kanti okuqukethwe komswakama kwezindawo ezisele kuhlala cishe ku-45%, okungagcini nje ngokwandisa izindleko zokuhamba kodwa futhi kubeka engcupheni yezijeziso zemvelo.
Isixazululo
Siklame ngokukhethekileumshini wokuhlunga we-hydraulic ozenzakalelayo onezinhlaka zensimbi ezingagqwali ezingu-630ngakho.

1. Uhlaka lwensimbi engagqwali, olumelana ngokuphelele namagesi agqwalisayo kanye noketshezi endaweni yezimayini
2. Uhlelo lwe-hydraulic olunomfutho ophezulu, oluhlanganiswe namapuleti okuhlunga e-polypropylene aqinisiwe, lukhulise amandla okucubungula okukodwa afinyelela kumamitha ayi-cubic angu-3.8.
3. 3 Uhlelo lokulawula lwe-PLC oluhlakaniphile luvumela ukusebenza okuzenzakalelayo ngokuphelele, kunciphisa inani labasebenzi ngezingxenye ezimbili kwezintathu.
4. Umklamo wokuqhaqha okusheshayo we-modular unciphise isikhathi sokushintsha indwangu yesihlungi kusuka emahoreni ama-2 kuya kumaminithi angama-30.

Ukusebenza kahle kokusebenza
Ngemva kokuba imishini isiqalile ukusebenza, yabonisa izinzuzo ezibalulekile ngokushesha: okuqukethwe komswakama we-tailings kwalawulwa ngokuzinzile ngaphakathi kwebanga lika-33%-35%, kuhlangatshezwane nezindinganiso zokuvikela imvelo zendawo; amaqoqo okucubungula nsuku zonke akhushulwe kusuka ezikhathini ezingu-8 kuya ezikhathini ezingu-12; okwamangaza nakakhulu ukuthi ngemva kokusebenza okuqhubekayo izinyanga ezingu-8, uhlaka lomshini lwahlala luhlanzekile njengolusha, ludinga ukulungiswa okuvamile kuphela. Ikhasimende labala: uma kuqhathaniswa nemishini endala, izindleko zokusebenza eziphelele zonyaka zongiwe cishe ngama-$90,000, kanti isikhathi sokubuyiselwa kwemali sasingaphansi kwezinyanga ezingu-14.

“Lo mshini wokuhlunga ushintshe ngokuphelele inqubo yethu yokucubungula ama-tailings. Manje sesingakwazi ukusingatha amathani engeziwe angu-200 ezinto zokwakha nsuku zonke, futhi asisadingeki sikhathazeke ngokuthi imishini izophuka ngokuzumayo.” —— Ukuhlolwa okwenziwe ngumqondisi wesitshalo sokusiza amakhasimende embikweni wokwamukelwa.
