ʻO kahi rig drill down-the-hole, i ʻike ʻia ʻo DTH drill rig, he mīkini ikaika i hoʻohana ʻia i nā ʻoihana like ʻole no ka ʻeli ʻana i nā lua i ka lepo.Hoʻohana maʻamau ia i ka ʻeli ʻana, kūkulu, a me ka ʻimi ʻaila a me ke kinoea.E wehewehe ana kēia ʻatikala i ka hana ʻana o kahi rig drill down-the-hole a me kāna mau kumu kumu.
ʻO ke kumumanaʻo hana o kahi pahu hoʻoheheʻe i lalo e pili ana i ka hui pū ʻana o nā ʻano hana wili a me nā mea hana.Hoʻokomo ʻia ka pahu drill me kahi hāmare, i hoʻopili ʻia i ka hope o ke kaula drill.Hoʻokele ʻia ka hāmare e ka ea kaomi a i ʻole ka mana hydraulic a loaʻa kahi piston e paʻi i ka bit drill.ʻO ka drill bit ke kuleana no ka uhaʻi ʻana i ka pōhaku a i ʻole mea lepo a hana i puka.
Ke hoʻohana ʻia ka rig drill, hoʻololi ʻia ke kaula drill e ke kumu mana o ka rig, e like me ka ʻenekini a i ʻole ka motika.Ke kaʻawili ʻana o ke kaula drill, neʻe ka hāmare a me ka bit drill i luna a i lalo, e hana ana i kahi hopena hammering.Paʻi ka hamare i ka bit drill me ke alapine kiʻekiʻe a me ka ikaika, e ʻae iā ia e komo i ka lepo a i ʻole ka pōhaku.
Ua hoʻolālā kūikawā ʻia ka drill bit i hoʻohana ʻia i loko o kahi pahu hoʻoheheʻe i lalo no ka wili ʻana.Hana ʻia ia i nā mea paʻakikī, e like me ka tungsten carbide, e pale i ka hopena kiʻekiʻe a me ka abrasion i ka wā wili.Loaʻa paha nā ʻano a me nā nui o ka drill bit ma muli o nā koi wili kikoʻī.
No ka hōʻoia ʻana i ka hoʻoheheʻe maikaʻi ʻana, hoʻohana pinepine ʻia ka wai a i ʻole ka wai wili i ka wā o ke kaʻina hana.Kōkua ka wai wili e hoʻomāalili i ka bit drill, wehe i nā ʻoki ʻia, a hāʻawi i ka lubrication.He kōkua nō hoʻi ia e hoʻopaʻa i ka lua a pale i ka hāʻule.
Hoʻokomo maʻamau ʻia ka puʻu hoʻoheheʻe iho ma luna o kahi kolo a kaʻa paha no ka neʻe maʻalahi.Hoʻohana ʻia ia e nā mea hana akamai e hoʻomalu i nā ʻāpana wili, e like me ka wikiwiki o ka hoʻololi ʻana, ka hammering frequency, a me ka hohonu o ka wili.Loaʻa paha i nā rigs drill kiʻekiʻe nā hiʻohiʻona a me nā mana kamepiula no ka hoʻonui ʻana i ka pololei a me ka pono.
I ka hopena, hana ʻia kahi pahu hoʻoheheʻe i lalo ma ka hoʻohui ʻana i nā ʻano hana wili a me nā mea hana.ʻO ka hāmare, i alakaʻi ʻia e ka ea kaomi a i ʻole ka mana hydraulic, hahau i ka drill bit me ke alapine kiʻekiʻe a me ka ikaika e wāwahi i ka lepo a i ʻole ka pōhaku.ʻO ka drill bit, i hana ʻia me nā mea paʻakikī, komo i ka lepo i ka wā e kaʻa ai ke kaula drill.Hoʻohana ʻia ka wai a i ʻole ka wai wili no ka hoʻomaikaʻi ʻana i ka pono wili.Me kona mana ikaika a me ka mana pololei, ʻo ka down-the-hole drill rig he mea pono i nā ʻoihana like ʻole.
