Summary: Ukukhiqizwa kwamagama ahlanganisiwe ngokuvamile kuhilela izinqubo ezimbalwa eziyinhloko ezifana nokuhlabeka, ukuhlunga, ukwenza isihlabathi, nokuhlukanisa up powder wesihlabathi....
Nakuba i-teknoloji yokusebenza ngokuvamile yezinto ezixutshwe ngokuvamile seyiqeqeshwe kakhulu, umkhondo wokusebenza okukhethekile wokukhiqiza izinto ezixutshwe ngokuvamile uhluke ngokuya ngesikali sokukhiqiza, izici zezinto ezisetshenziswayo, izidingo zemarkethi zezimpahla, nezindleko.
Ukucwiliswa kuyadingeka kakhulu
Ukucwiliswa kuyindlela ebalulekile kakhulu ekulungiseleleni ama-aggregate esihlabathi nesiqathana. Ngaphandle kwesingxenye yezitsha zezitshalo ezimhlophe kakhulu ezingasetshenziswa ngqo ekugcineni kwamanzi, izitshalo eziningi ezinqabile ziyadingeka ukuba zitholwe futhi zicwilwe.
Ukukhetha ukuthi zingaki izigaba zokugrahaya ezidingekayo efekthri yokukhiqiza, sidinga ukucabangela usayizi omkhulu wepheshana lezinto ezisezingeni lokuqala kanye nosayizi wepheshana lomkhiqizo wokugcina. Ngokusho kwezinga lemining nezindlela ezihlukahlukene, njll., usayizi omkhulu wepheshana lamatshe uvame ukuba phakathi kuka-200 mm no-1400 mm. Usayizi wepheshana lokudla lwezihlungi eziqondile eziphindaphindayo ngaphansi kuka-60mm, futhi usayizi wepheshana wokudla kwesikhumba se-rod uyancipha. Okwamanje, izinga lokugrahaya lwezihlungi eziqondile ezisetshenziswa kakhulu lincane kune-10, ngakho ukukhiqizwa kwe-sand ne-gravel aggregates ngokuvamile kudinga izigaba ezimbili noma ezintathu zokugrahaya.
Uhlobo ezintathu zokuhlola
Kwimpahla yokukhiqiza yonke, ukuhlunga kungahlukaniswa ngezindlela ezintathu: ukuhlunga kwangaphambili, ukuhlunga kokuhlola, nokuhlunga komkhiqizo.
Uma inani lolwandle noma izinhlayiya ezincane ezisemzimbane olukhulu, ukukhiqiza okuqala kudingeka ukuze kuqoshwe umhlabathi nezinto ezincane emzimbane, oku, ngesandla esisodwa, kungavimbela impahla evela ephucwe kakhulu, kanti ngakwesinye icala, futhi kunciphisa inani lempahla eya emishini yokucisha elikhulu, okuthuthukisa amandla okusebenza kwesigxobo.
Ukukhangela ukwahlukaniswa ngokuvamile kubekwa ngemuva kwesigaba sokucisha okugqithile ukuze kuhlukaniswe izinto ezinkulu kunesilinganiso esithile sezithambisi bese kubuyiselwa emashinini okucisha okucisha okuncane ukuze kuqhubeke ukucisha, ukuze lawulwe ubukhulu bezithambisi ezicishwe ukuze kuhlangabezane nesilinganiso sezithambisi eziphumayo esidingwa yisigaba esilandelayo.
Ukwahlukaniswa kwezinto ezivelisiwe kuyindlela yokulinganisa izinto ezicishwe okugqithile noma i-sand ukuze kutholakale imveliso ene-gradation ehlukene.
Isigaba sokwenza nokwakha ithafa ukuze kutholakale ukuma okuhle kwemigqa yamapheshana
Ngekhwalithi ezahlukene zezinto ezomisiweyo kanye nokusebenza kwezixazululo zokucisha, ingxenye ethile yomisiweyo emncane izoveliswa ngesikhathi sokucisha. Nokho, le ngxenye yomisiweyo ivame ukuba nezinkinga ezinjengokungafani kahle kwesakhiwo sezinhlayiya kanye nokuveliswa okuncane kwesihlabathi. Uma kudingeka kuveliswe inani elikhulu lesihlabathi esenziwe yimishini esiphezulu, kudingeka kusetshenziswe isithuthuthu sokuthinta esiqondene nomkhumbi sokulungisa nokuqondisa isihlabathi.
Ukuhlukanisa uthuli nokothi ukuze kulawulwe ukumuncwa kwephutha futhi kuthuthukiswe izinga lomkhiqizo
Ngesikhathi senqubo yokwenza usimende, kuzokwenzeka ukukhiqizwa kwezabelo ezimbalwa zikakhonkolo, futhi okuqukethwe okuphezulu noma okuphansi kwekhonkolo kuzothinta ukusebenza komsebenzi wegandaganda. Ukwahlukanisa usimende nesilika kungukuphatha ukungena kwekhonkolo kumphumela wokugcina.
Izindlela ezivame ukusetshenziswa zokwenza imatofana nokumba nokuhlukanisa ibhande nombhobho zingahlukaniswa zaba izindlela ezomile nezimanzi ngokusekelwe ekutheni amanzi asetshenziswa njengendlela yokusebenza. Lo chati olulandelayo lukhombisa umehluko omkhulu phakathi kwezindlela ezomile nezimanzi:
| Izinhlobo | Indlela yokomisa | Indlela yokwamanisa |
| Umbuso obalulekile | Okuqukethwe okuphansi komhlabathi kumaminerali angaqedi, kulula ukuhulula umhlabathi | Okuqukethwe okuphezulu komhlabathi kumagold e-ore angafakwanga, kuthatha isikhathi ukumunca umhlabathi |
| Ukuvikelwa Kwendawo | <10mg/m³, equipped with a high-efficiency bag dust collector, no sewage | Ayikho i-dust, ilayini yokukhiqiza kudingeka ihlanganiswe namakhono afaneleyo wokwelapha amanzi angcolile, amanzi angcolile ajikijwe |
| Ukusetshenziswa kwamandla | Okuncane | Okukhulu ngokulinganayo |
| Ixabiso lokuqasha | Okuncane | Okukhulu ngokulinganayo |
| Ukuphathwa kokukhiqiza | Izinsimbi ezincane, ukuphathwa kulula, umsebenzi oqine | Izinsimbi eziningi, ukuphathwa kokukhiqiza kunzima kakhulu, futhi kudingeka izidingo eziphezulu ezabasebenzi ngenxa yokusebenza |
| Indawo yokwakha | Encane | Isinqumo sezindlela zokwelapha impahla yamanzi sinomhlaba omkhulu |
| Ukusetshenziswa kwamanzi | Uthuli olukhulu olukhulu kuphela oludingayo amanzi amancane | Ludingayo amanzi amaningi okusheshisa |
| Ukuhlukaniswa kwesihlabathi kanye nomquba | Thatha isihlukanisi ukukhetha upulazi | Indlela emanzi yokuwasha usawoti ingaba nokusebenza okuphezulu |
| Ukugcina | Indawo yokugcina noma i-shed | I-shed kuphela |
Nakuba imininingwane yokwenza nokuthuthukisa izinto ezifana nesihlabathi nezigqoko seyiqeqeshwe kahle, akuyona inqubo yokwenza enqunyiwe ezweni lokwenza ngokomqondo, futhi ukukhetha izinsiza zokwenza kungenzeka kakhulu futhi kuhlukahlukene.
