Hoʻokaʻawale a me nā loina hana o nā mīkini wili pōhaku

ʻO nā mīkini hoʻoheheʻe pōhaku, ʻike ʻia hoʻi ʻo nā drills pōhaku a i ʻole nā ​​​​mea haʻihaʻi pōhaku, he mau mea pono i hoʻohana ʻia i nā ʻoihana like ʻole e like me ka mining, kūkulu, a me ka ʻimi ʻana.Ke manaʻo nei kēia ʻatikala e hāʻawi i kahi ʻike o ka hoʻokaʻawale kumu a me nā loina hana o nā mīkini wili pōhaku.

I. Hoʻokaʻawale ʻana i nā mīkini wili pōhaku:

1. Nā Hana Pōhaku Paʻa Lima:
- Pneumatic Hand-held Rock Drills: Hoʻohana ʻia kēia mau mea hoʻoheheʻe e ka ea paʻa a hoʻohana mau ʻia no nā hana wili liʻiliʻi.
- Nā Pahu Pōhaku Uila: Hoʻohana ʻia kēia mau hana e ka uila a kūpono ia no nā hana wili i loko a i ʻole nā ​​​​wahi me ka ventila liʻiliʻi.

2. Nā Kau ʻana Pōhaku:
- Pneumatic Mounted Rock Drills: Hoʻokau ʻia kēia mau drills ma luna o kahi rig a i ʻole ke kahua a hoʻohana mau ʻia i nā ʻoihana mining nui a me nā hana kūkulu.
- Hydraulic Mounted Rock Drills: Hoʻohana ʻia kēia mau drills e nā ʻōnaehana hydraulic a ʻike ʻia no ko lākou kiʻekiʻe drilling efficiency a versatility.

II.Nā Kuʻuna Hana o nā Mīkini wili pōhaku:
1. ʻO ka wili ʻana:
- ʻO ka wili percussion ka ʻenehana wili maʻamau i hoʻohana ʻia i nā mīkini wili pōhaku.
- Paʻi pinepine ka drill bit i ka ʻili pōhaku i ke alapine kiʻekiʻe, e hana ana i nā haʻihaʻi a me ka wehe ʻana i nā ʻāpana pōhaku.
- Hoʻopili ʻia ka pahu drill i kahi piston a i ʻole ka hāmare e neʻe wikiwiki a i lalo, e hāʻawi ana i ka ikaika hopena i ka ʻili pōhaku.

2. ʻO Rotary Drilling:
- Hoʻohana ʻia ʻo Rotary drilling i ka wā e wili ai ma waena o nā papa pōhaku paʻakikī.
- Kaʻawili ʻia ka bit drill i ka wā e kau ana i ke kaomi i lalo, wili a haki i ka pōhaku.
- Hoʻohana mau ʻia kēia ʻenehana i nā hana ʻeli hohonu, e like me ka ʻimi ʻaila a me ke kinoea.

3. ʻO ka wili ʻana ma lalo o ka Hole (DTH):
- ʻO ka wili DTH he ʻano like ʻole o ka wili percussion.
- Hoʻopili ʻia ka pahu drill i kahi kaula drill, a laila hoʻohaʻahaʻa ʻia i loko o ka lua.
- Hoʻokuʻu ʻia ka ea i hoʻopaʻa ʻia i lalo i ke kaula drill, hoʻopilikia i ka bit drill a haki i ka pōhaku.

He kuleana koʻikoʻi nā mīkini wili pōhaku i nā ʻoihana like ʻole, e hiki ai i nā hana wili a pololei.ʻO ka hoʻomaopopo ʻana i ka hoʻohālikelike kumu a me nā loina hana o kēia mau mīkini he mea nui ia no ke koho ʻana i nā lako kūpono no nā noi kikoʻī.Inā paʻa lima a kau ʻia paha, hoʻohana ʻia e ka ea, ka uila, a i ʻole hydraulics, e hoʻomau nei nā mīkini wili pōhaku e hoʻokō i nā koi o nā ʻoihana hou.
