Ngempela, ukuhlanganiswa kwamabhola okugaya angu-65mm phakathi kwezigayo zensimbi kuyingxenye ebalulekile yokucubungula izimbiwa emisebenzini yezimayini.Le mithombo yokugaya enosayizi omkhulu idlala indima ebalulekile enqubweni yokugaya insimbi, iqhubekisela phambili ukucwengwa kwensimbi eluhlaza ukuze kukhiqizwe izinhlayiya ezicolekile ezibalulekile ekukhishweni kwezimbiwa.
Ebekwe phakathi kwezigayo, amabhola okugaya angu-65mm ahlanganyela ngokuqhubekayo enqubweni yokuhlanganisa.Ububanzi bazo obukhulu buzinikeza inzuzo ebalulekile ekukhiqizeni amandla omthelela amakhulu ngesikhathi kushayisana nensimbi eluhlaza.Leli khono elingokwemvelo lokuletha amandla omthelela anamandla linikela ngokuphawulekayo ekugayeni okuphumelelayo nasekuncishisweni kwensimbi eluhlaza ibe yizinhlayiya ezicolekile.Ubukhulu obukhulu bala mabhola ensimbi buwavumela ukuba asebenzise amandla amakhulu phezu komthelela, esiza ekuqhekekeni kwezinsimbi futhi enze kube lula ukwakhiwa kwezinhlayiya ezicolekile ezibalulekile ezinqubweni zokukhishwa kwezimbiwa ezilandelayo.
Ukusetshenziswa kwamabhola okugaya angu-65mm phakathi kwezigayo zensimbi kugcizelela indima yazo njengendlela esebenzayo yokubhidliza kanye nokucwengisiswa kwensimbi eluhlaza.Ubukhulu bazo obukhulu buzinikeza amandla okusebenzisa amandla amakhulu, okunomthelela ekugayeni okuphumelelayo nasekuncishisweni kwensimbi eluhlaza ibe yizinhlayiya ezicolisekile.Empeleni, lezi zindaba zokugaya ezinosayizi omkhulu ziyizingxenye ezibalulekile ohlelweni lokugaya insimbi ngaphakathi kwemisebenzi yezimayini, okuqinisekisa ukukhiqizwa kwezinhlayiya zomhlabathi ezidingekayo ukuze kukhishwe amaminerali abalulekile.
