Pono e kokoke ka hana ʻana o ke one a me ka ʻiliʻili, e like me nā palena o nā kumuwaiwai a me nā kūlana halihali. Ma waho aʻe o ka laulā palekana o ka pahū ʻana o ka mine, me ke kumukūʻai halihali o nā mea maka a me nā huahana i hoʻopau ʻia, e kūkulu ʻia ka laina hana ma kahi kokoke. ʻO nā pahuhopu anamanaʻo nui ka wahi honua o ke kahua one a me nā kumuwaiwai i loaʻa, a aia kahi hoʻolālā laulā no kahi o ka laina hana.

2, hoʻolālā i ke kaʻina hana one
Ua hoʻolālā ʻia ke kaʻina hana one e lilo i ʻekolu pae o ka wili ʻana, ʻo ia hoʻi, ka wili mua, ka wili waena, a me ka wili maikaʻi.
Hoʻoili ʻia ka ʻai granite i ke kahua hoʻoiho o ka hale hana wili, a lawe ʻia ka granite me ka nui o ka ʻāpana ma lalo o 800 mm e ka mea hānai haʻalulu me ka mea kānana; hāʻule pololei ka granite ma lalo o 150 mm ma luna o ka mea lawe kāʻei a komo i loko o ka pā hale mālama mua; ʻo ka mea nui ma mua o 150 mm Ma hope o ka wili mua ʻana o ka mīkini wili ʻauwae, hoʻouna ʻia hoʻi ka mea haʻihaʻi i ka pā hale mua. Ma hope o ka nānā mua ʻana ma o ka pale haʻalulu, kānana pololei ʻia ka mea ma lalo o 31.5 mm, a komo ka mea me ka nui o ka ʻāpana ma mua o 31.5 mm i ka wili waena o ka mīkini wili hopena. Ma hope o ka wili ʻana a me ka nānā ʻana, komo maikaʻi nā mea ma luna o 31.5 mm i ka mīkini wili. Ma hope o ka wili ʻana, komo lākou i loko o ka pale haʻalulu pōʻai ʻekolu papa a ua wili ʻia i ʻekolu nui o nā ʻāpana pōhaku granite o 0 a 5 mm, 5 a 13 mm a me 13 a 31.5 mm.
ʻO nā lako i hoʻohana ʻia i ka wāwahi mua ʻana he mea wili ʻāwae, a ʻo nā lako i hoʻohana ʻia i ka wāwahi ʻana ʻo ia ka mea wili hopena a me ka mea wili hopena, a ʻo nā mea wili ʻekolu a me ka hale hana kānana e hana pū i kahi hana hana loop pani.

3, mālama huahana i hoʻopau ʻia
ʻO nā ʻāpana grit granite ʻekolu me nā nui ʻāpana like ʻole ma hope o ka hala ʻana i ka wāwahi ʻana a me ka kānana ʻana e lawe ʻia i loko o ʻekolu mau panakō poepoe 2500 t ma o nā kāʻei.
