I nā makahiki ʻelua i hala iho nei, ua hoʻonui ʻia ka drill pōhaku o ka leg leg drill me ka mana hopena nui ma ka mākeke, a ua hoʻonui ʻia ka drill pōhaku o kahi ʻāpana o ke ʻano kiʻekiʻe kiʻekiʻe a me nā pihi pihi liʻiliʻi.ʻO ke pihi pihi anawaena liʻiliʻi e like me ka huahana nui i ka ʻoihana brazing a me ka ʻoihana kila e hoʻolohe i kēia ʻano hoʻomohala.
Me ka wikiwiki o ka hoʻomohala ʻana i nā hana kūkulu hale ma Kina, ʻo ka hoʻohana ʻana i ka ʻeli pōhaku hydraulic a me nā kaʻa wili, ʻoi aku ka nui o ka hoʻoheheʻe ʻana i nā pōhaku hydraulic open-air a me nā kaʻa wili, e hōʻike ana i ka piʻi nui ʻana.Kekahi wai nui a me ka uila kahua kūkulu ma Kina, nui pohaku mala a hiki i kanaka hana e kuai hydraulic kaa wili pōhaku i ka helu o ka hoonui.ʻO nā hiʻohiʻona o nā kaʻa hoʻoheheʻe hydraulic, e like me ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe o ka hoʻohana ʻana i ka ikehu, ka manawa pani pōkole kōkua a me ka ʻoihana hana maikaʻi, ua uku nui ʻia e ka ʻoihana wili pōhaku.I kēia manawa ua hoʻoponopono nā mea hana haole nui o nā mīkini wili pōhaku i ke kumukūʻai kūʻai aku o ka wili pōhaku hydraulic a me nā kaʻa wili no nā manawa he nui e like me nā kūlana aupuni o Kina.Ua hoʻonui ʻia ka nui o ka hana ʻana o nā ʻoihana kūloko a me nā ʻoihana kālā ʻē aʻe, e hōʻike ana e hiki ke hoʻohana ʻia ka hoʻohana ʻana i ka hoʻoheheʻe pōhaku hydraulic a me nā kaʻa wili i Kina, a e piʻi aʻe hoʻi ke koi no ke kākoʻo ʻana i ka wili pōhaku a me nā mea hana wili.
ʻO ka mea hoʻoheheʻe DTH he mīkini wili pōhaku ākea a nui i hoʻokele ʻia e ka ea compressed.I nā ʻāina hoʻomohala ʻenehana, hoʻohana wale ʻia nā mea hana drill DTH e like me nā mīkini wili no nā kahua kūkulu kūikawā.Loaʻa i ka DTH rock drill nā hiʻohiʻona o ka hana maʻalahi, hoʻohana maʻalahi, mālama maʻalahi a me ke kumu kūʻai haʻahaʻa.No laila, ua lilo ʻo DTH rock drill i ʻano mīkini wili pōhaku e hoʻololi i ke kaʻa wili pōhaku hydraulic i loko o ka hale ākea ākea a me ka ʻenekinia wili pōhaku nui.Eia nō naʻe, loaʻa nā mea pono ʻole DTH e like me ka haʻahaʻa haʻahaʻa haʻahaʻa, ka haʻahaʻa o ka hoʻohana ʻana i ka ikehu a me ka manawa hana kōkua lōʻihi.
ʻO ka pōhaku drill kahi mea kākoʻo o ka mīkini wili pōhaku, kāna mau ʻāpana huahana, koi mākeke, nā koi hana huahana, a me nā mea ʻē aʻe.Pono ka ʻoihana e hoʻoikaika i ka hoʻololi ʻana i nā ʻano like ʻole me nā ʻoihana hana ʻenekinia drilling a me nā ʻoihana hana mīkini wili.Hoʻopaʻa i ka manawa hoʻomohala o kēia mau māla e hoʻoikaika i ka hoʻomohala ʻana i nā huahana drill a me nā mea kila.
ʻO nā mea hana wili, nā mea hana wili ʻenekinia pōhaku, nā mea hana wili honua, nā mea hana wili hoʻopaʻa pōhaku a me nā mea hana wili lua ahi metallurgical he nui nā ʻano huahana me ka mākeke nui.Pono e nānā pono nā mea hana wili i ka ulu ʻana o ka mākeke o kēia mau huahana.
ʻO ka hoʻokumu ʻia ʻana o nā kaila hoʻolaha lehulehu e hoʻokuʻu aku i ka nui o nā mea hana hoʻoheheʻe kūloko i nā mākeke ʻē aʻe e hoʻoikaika nui i ka holomua o nā ʻoihana, hoʻomohala huahana a me ka hoʻonui ʻana i ka nui o ka ʻoihana.
