I ke kaiapuni ʻoihana wikiwiki o kēia lā, ʻaʻole i ʻoi aku ka nui o ke koi no nā mea hana wili kūpono, hilinaʻi, a maʻalahi hoʻi e hoʻohana. Inā paha e hana ana i ka mining, ke kūkulu ʻana i nā tunnel, a i ʻole nā ​​​​​​papahana wili like ʻole, pono nā ʻoihana i nā lako hana ʻaʻole wale nō ka hana maikaʻi loa, akā hiki ke hoʻoponopono i nā pilikia o nā kūlana hana paʻakikī. He paionia i ka ʻenehana wili a me ka hana maikaʻi loa: he ʻoihana e kālele nui ana i ka hana ʻanakoho pneumatics, nā ʻokiʻoki, nā wili pōhaku,wili pōhaku pneumatics, wili wāwae eas, wili pōhaku lima limas, a mekaʻa paikikala uilas, e hāʻawi ana i kahi laulā piha o nā huahana e hoʻokō ai i kēia mau koi koʻikoʻi.

Laina huahana like ʻole
ʻO ke kumu o ka holomua o kā mākou hui aia i kāna laina huahana like ʻole a ākea. ʻO ka waihona hoʻopukapuka kālā e komo pū ana me:
-Nā ʻōpeʻapeʻa pneumatic: Ua hoʻolālā kūikawā ʻia kēia mau ʻōpeʻapeʻa no nā hana kaumaha a kūpono hoʻi no ka wāwahi ʻana, ka ʻoki ʻana, a me ka wehe ʻana i nā hana. ʻO kona ʻano paʻa a me ka lakio mana kiʻekiʻe i ke kaumaha e lilo ia i mea nui no nā kahua eli a me ke kūkulu ʻana.

-Nā wili pōhaku a me nā wili pōhaku pneumatic: Ma ke ʻano he iwi kuamoʻo o kekahi hana wili koʻikoʻi, ua hoʻolālā ʻia kēia mau mīkini wili e wili i nā pōhaku me ka pololei a me ka wikiwiki i kūlike ʻole. Ma muli o ka mana o ka ea i hoʻopaʻa ʻia, hāʻawi kā lākou mana pneumatic i kahi pono hou aʻe o ka hōʻemi ʻana i ka luhi o ka hana.

-Mea wili wāwae ea: Hoʻohui kēia mau mea wili i ka pono me ka hana, e hōʻike ana i nā wāwae ea hiki ke hoʻololi ʻia e hiki ke hoʻokō i nā kūlana like ʻole a me ke kūpaʻa kūpono i ka wā o ka hana, e lilo ana lākou i koho kūpono no ke kūkulu ʻana i ke tunnel a me nā hana wili paʻakikī.
