Ukusetshenziswa kwamabhola okugaya angu-80mm kuyisisekelo sezinqubo zokugaya insimbi ngaphakathi kokusebenza kwezimayini.Le midiya yokugaya eqinile futhi enosayizi omkhulu idlala indima ebalulekile ekugayeni insimbi, ihlinzeka ngezinzuzo ezihlukile ngenxa yobukhulu bayo nezici zokugaya.
Ikakhulukazi, ngaphakathi kwesizinda se-Ore Grinding, ukubaluleka kwamabhola okugaya angama-80mm angeke kuncishiswe.Njengoba ebekwe phakathi kwezigayo zensimbi, lawa mabhola anosayizi omkhulu nagayayo athatha indima ebalulekile yokugaya imidiya.Ububanzi bazo obukhulu buzinika amandla okwenza umthelela omkhulu kanye namandla okuchoboza ngesikhathi sokusebenzisana nama-ore aluhlaza ngaphakathi kwemishini yokugaya.Lesi sici sibalulekile ekubambeni iqhaza ekugayeni okuphumelelayo nasekuncishisweni kwensimbi eluhlaza.Ngokusebenzisa usayizi wawo omkhulu nezici zokugaya, lawa mabhola ensimbi asiza ngokuphumelelayo ekucwengisiseni ama-ore, enze kube lula ukwakhiwa kwezinhlayiya ezigaywe kahle phakathi nenqubo yokugaya insimbi.
Ubukhulu obukhulu bamabhola okugaya angu-80mm buwanikeza ikhono lokuletha umthelela omkhulu namandla ahlabayo.Lesi sici sibalulekile ekuzuzeni ukugaywa okuphumelelayo kanye nokwehliswa kwe-ore eluhlaza, ngaleyo ndlela idlala indima ebalulekile ekucwengeni ama-ore nasekukhiqizeni izinhlayiya ezicolekile ezibalulekile ezigabeni zokumbiwa kwezimbiwa ezilandelayo.
Empeleni, ukusetshenziswa okuyinhloko kwamabhola okugaya angu-80mm ezimayini ngokuyinhloko kuzungeza indima yawo ebalulekile njengemidiya ebalulekile yokugaya ngaphakathi kwezigayo zensimbi.Ubukhulu bazo obukhudlwana kanye nemvelo yokugaya kuzihlomisela ukuba zibe nomthelela omkhulu kanye namandla okuchotshozwa, okunikela ekugayeni okuphumelelayo nasekuncishisweni kwensimbi eluhlaza.Le nqubo iphumela ekukhiqizweni kwezinhlayiya zomhlabathi ezicolekile ezidingekayo ezigabeni ezingezansi zomfula zokumbiwa kwezimbiwa, kugcizelela ukubaluleka kwalezi zindaba zokugaya ezinosayizi omkhulu kanye nokugaya ohlelweni lokugaya insimbi phakathi nemisebenzi yezimayini.
