Umzi-mveliso wokuvelisa amandla ufuna ukunxiba nzima kunye neebhokisi zegiya ezisebenzayo ukuhlangabezana neemfuno zemathiriyeli eninzi. Sihambisa izixhobo ezifunwa lishishini ukugcina umthumeli wabo kunye ne-stacker reclaimer drives zisebenza ngokugqibeleleyo. Iimpawu eziphambili ezifana nokusebenza kakuhle kwe-thermal, ukunyuswa kunye neenkqubo zokutywina ziphuculwe ukuqinisekisa ukusebenza okuphezulu kwizicelo zokuvelisa amandla.
Iisistim zegiya zingqinwe ukuba zimelana neemeko ezirhabaxa zokusila kwaye zenziwe ngobunjineli bokufikelela ngokuthe ngqo iimfuno zabathengi ukuqinisekisa ukusebenza okuphezulu.
