20mm iiBhola eziQonxiweyo/ eziqengqelekayo zokuSila
Iibhola zokusila ezinobukhulu obuyi-20mm ububanzi zidlala indima ebalulekileyo kwiinkqubo zokukhutshwa kwezimbiwa zokucolwa kwentsimbi kunye nokusila kwimisebenzi yasezimayini.Ezi yunithi zentsimbi zingqukuva zisebenza njengoomatshini bokugaya oomatshini abasetyenziselwa ukucokisa iintsimbi ezikrwada ezikrwada zibe zizimbiwa ezixabisekileyo.
Ukutyunyuzwa kwentsimbi ekrwada kubandakanya isigaba sokuqala sokutsalwa kwezimbiwa.Intsimbi ekrwada ekrwada, efunyenwe kwimisebenzi yasezimayini, iqulathe iiminerali ezibiyelwe phakathi kwamaqhekeza amakhulu amatye okanye imizimba ekrwada.Ukukhulula ezi zimbiwa zixabisekileyo, intsimbi ekrwada ekrwada ingena kwinkqubo yokutyumza.Oku kubandakanya ukusetyenziswa koomatshini bokungqusha abaxhotyiswe ngamagumbi apho intsimbi ekrwada ekrwada ibekwe ecaleni kweebhola zokusila ezingama-20mm.Ezi bhola zincedisa ekuqhekekeni kwezinto eziluhlaza, ziqhekeza zibe ngamancinci amancinci, alawulekayo.Iibhola zetsimbi, ngempembelelo yazo kunye nokuxutywa kwe-ores, zinciphisa ngokufanelekileyo ubukhulu be-ore, ziququzelele ukutsalwa kweeminerali ezixabisekileyo.
Emva koko, iNkqubo yokuSila icokisa intsimbi ekrwada ngakumbi ukuze ifumane ubungakanani obunqwenelekayo bamasuntswana.Izinto ezichotshoziweyo, kunye neebhola ze-20mm zokugaya, zingeniswa kumatshini ojikelezayo wokugaya.Njengoko umatshini ujikeleza, iibhola zentsimbi ngaphakathi kwegumbi lokugaya zenza umphumo we-cascading, ukungqubuzana neentsimbi.Olu ngquzulwano, ludityaniswe nokukhuhlana okwenziwa kukujikeleza komatshini wokungqusha, kutyumza ngokufanelekileyo kwaye kusila iintsimbi zibe ngamasuntswana acolekileyo.Isenzo esihambelanayo seebhola zetsimbi sinceda ekufezekiseni ukucokiseka okufunekayo kwiinkqubo zokutsalwa kweeminerali ezilandelayo.
Ukukhethwa kweebhola ze-20mm zokugaya zicwangcisiweyo, njengoko ubukhulu bazo kunye nobunzima bawo bufaka isandla ekucuthweni okusebenzayo kunye nokugaya.Ukuqina kunye nokuqina kwezi bhola zetsimbi zivumela ukusetyenziswa ixesha elide ngaphakathi koomatshini bokugaya, ukuqinisekisa ukusebenza okuhambelanayo ekuphuleni i-ores eluhlaza.
Ngamafutshane, ukudityaniswa kweebhola zokusila eziyi-20mm njengemithombo yokusila ekuxotyweni kwentsimbi ekrwada nakwiinkqubo zokusila ngaphakathi kwemisebenzi yasezimayini kubalulekile ekufezekiseni ukuncipha kobungakanani bamasuntswana, okwenza ukuba ukutsalwa kwezimbiwa ezixabisekileyo kubalulekile kumashishini ahlukeneyo.
