Umgodi omkhulu wamalahle e-China - i-Haerwusu Open Pit Mine.Umgodi wamalahle ufumaneka kwi-Inner Mongolia Autonomous Region City, iZhungeer Qi Ordos (Xuejiawan) i-Eastern genera kule ndawo, iNorth iye yakhiwe kwi-Heidaigou Open-pit Coal mine. Zininzi iirola zokuhambisa imigodi ezisetyenziswa emgodini.Oovimba bamalahle abanokubuyiswa ziitoni ezili-17.3, ubukhulu bomthungo wamalahle buziimitha ezingama-21.01, wonke umndilili wokuhluba umlinganiselo yi-6.626 cubic metres ngetoni nganye.Ubomi benkonzo yoyilo yiminyaka engama-79.Umgodi wamalahle wokuqala ugcina i-6.36 yeetoni, kunye ne-avareji yokuhluthwa kwe-4.099 cubic metres ngetoni nganye, kunye nobomi benkonzo yeminyaka engama-32.

Umgodi wamalahle wothuthu, isulfure ephantsi, iphosphorous ephantsi, iguquguqukayo ephezulu, ixabiso eliphezulu lecalorific, indawo yokunyibilika kothuthu lwamalahle amadangatye amade, aziwa ngokuba “ngamalahle aluhlaza”, amalahle anamandla akumgangatho ophezulu, anethemba elibanzi lemarike. Itekhnoloji yokwembiwa kwemigodi yamalahle kunye nokulandela umkhondo ngebhakethi enye yokwemba umhlakulo kunye nelori kunye nomsebenzi wokuqhawula i-dragline stripping.Yonke imihla isigebenga sehlabathi esibandakanya iilori ezizithululayo ngokwazo liqela lezothutho ezinzima kakhulu eliqokelelene apha, oku kwaziwa ngokuba yi "iron kunye neQela leNsimbi lokuSebenza kweMigodi" ephuma ngokungxama kwindawo yemigodi yaseWujin, yenza ixabiso elikhulu.

Umgodi wamalahle ovulekileyo ufumaneka kwi-Ordos Plateau, enye yezona ndawo zinzima kakhulu zamanzi kunye nokukhukuliseka komhlaba eChina.Umjelo wokuqala womphezulu uthe nkqo kwaye uthe tyaba, uhlaza lugqagqene, ukhukuliseko lomoya kunye nokuba yintlango kubi kakhulu, kwaye imo engqongileyo yendalo imbi kakhulu.Ukususela kulwakhiwo olusisiseko, umgodi wamalahle ovulekileyo uya kulungelelaniswa nophuhliso kunye nohlaza.Uphuhliso olusempilweni lomgodi wamalahle lulungile kwimarike yeerola zokuhambisa imigodi.

Owona mgodi mkhulu wamalahle ehlabathini – umgodi wamalahle waseRochester.Umgodi wamalahle ukwiPowder River Basin yaseWyoming, ngowona mgodi mkhulu ehlabathini oneetoni ezingama-23.Lo mgodi ukwangowona mmandla mkhulu wehlabathi wamalahle, yinkampani yePeabody energy. Rhoqo ngonyaka lo mgodi uthenga iirola zokuhambisa imigodi ezininzi.Ibhedi yamalahle kumgodi wamalahle waseRochester ithatha i-18.3 yeemitha zomgangatho ongaphezulu we-76.2 yeemitha kwaye ilula kangangeekhilomitha ezingama-80.47.Lo mgodi ugubungela ummandla oziikhilomitha ezingama-258.9, olingana nobukhulu baseWashington, D. c.. Oovimba beCarbon abamalunga neetoni ezingama-30.Kuthatha iminyaka engama-25 ukuya kwengama-30 ukugqiba lo mgodi.Ukuveliswa kwamalahle eRochester kwaziwa njengelona lahle licocekileyo, ubushushu obuqhelekileyo bamalahle ngeponti ye-8800 yaseBrithani ye-thermal units, kunye nomxholo wesulfure ongaphantsi kwe-0.2%.

Amalahle asebenzise i-dragline overcast stripping kunye nebhakethi enye kunye netekhnoloji yelori, athembele kubukhulu obukhulu, izixhobo ezinoomatshini kakhulu, ziphucula kakhulu ukusebenza kakuhle.Suku ngalunye, malunga neehambo ezingama-21 zoololiwe abathwele amalahle ziya kuqhuba zisuka kumgodi wamalahle e-Wyoming eRochester ziye kumaziko ombane ali-100 okubaselwa ngamalahle kwilizwe liphela.Nkqu iilori zamalahle ezipakwe kwiplanti yomgodi wamalahle eRochester ziyakwazi ukulayisha ngaphezulu kweetoni ezingama-440. Esi sixeko saziwa ngokuba "liziko lomfanekiso wehlabathi", "isixeko seentyatyambo", rhoqo entwasahlobo, iintyatyambo ziyaqhakaza, kwaye ngaloo ndlela "iintyatyambo". isixeko” ehlabathini.
