Hoʻonui i ke kūpaʻa hopena o ka mea ʻokiʻoki mining: Hōʻike ka loea US 10 makahiki i nā noi Diamond Enhanced Compact (DEC)
Ma hope o ka hala ʻana o hoʻokahi ʻumi makahiki ma ka ʻoihana wili pōhaku ma ʻAmelika Hui Pū ʻIa, ua ʻike maka au i nā ʻeha poʻo he nui mai ke kūpaʻa ʻana i ka hopena o nā mea ʻokiʻoki subpar—nā mea ʻoki i puhi ʻia i ka wā o ka ʻeli ʻana i nā pōhaku paʻakikī ma Colorado, ka manawa hoʻomaha mau no nā pani ma nā lua lanahu o Texas, a me nā kumukūʻai hana e piʻi nui ana e hoʻohilahila ai i nā luna o ka lua. Akā ua loli ka pāʻani i ka wā i oʻo ai ka ʻenehana diamond enhanced compact (DEC), ʻoiai me ka hoʻohana nui ʻia ʻana o ka Conical diamond enhanced compact. Ma ke ʻano he kanaka i haumia kona mau lima i nā lua ma lalo o ka honua a me nā hale hana ma ʻAmelika Hui Pū ʻIa, e ʻae mai iaʻu e wehewehe pehea i hoʻololi ai kēia huahana i ke kūpaʻa ʻana i ka hopena o nā mea ʻokiʻoki mai kahi hiʻohiʻona boots-on-the-ground.
Hana Lima i Hōʻoia ʻia: Ke Kuamoʻo o ke Kūʻē Hopena o ka Conical Diamond Enhanced Compact
Ma ka ʻoihana mining o ʻAmelika Hui Pū ʻIa, ke ola nei mākou ma muli o ka mantra "ʻaʻohe ala pōkole ma ka hana" - a hāʻawi ka Conical diamond enhanced compact i kēlā. ʻO ke kī i kona paʻakikī aia i ka hana ʻana me ka akahele, aʻu i hōʻoia ponoʻī ai i ka wā o nā kipa hale hana. ʻO ka mea nui loa no ke kūpaʻa ʻana i ka hopena o ka mea ʻoki ʻo ia ka pilina ma waena o ka papa daimana a me ka substrate carbide, kahi mea hana a haki paha aʻu i hoʻāʻo pinepine ai. Hoʻohana kēia huahana i ka ʻenehana polycrystalline diamond compact core, me ka mahana a me ke kaomi i hoʻoponopono ʻia i nā hapa o ke kekelē a me ka psi - kahi mea a nā mines o ʻAmelika Hui Pū ʻIa e koi ai no ke kūlike.
Ua like ke koʻikoʻi o ke koho ʻana i nā mea maka: ua piʻi ka maʻemaʻe o ka daimana i ka 99.9%+, a ua hele ka paʻakikī o ka substrate carbide i ʻekolu mau puni o ka hoʻāʻo ʻana o ka ASTM-standard. Ua ʻike maka au i kā lākou kaʻina hana hoʻomalu maikaʻi: ʻo kēlā me kēia pūʻulu o ka Conical diamond enhanced compact e kū i 5,000 mau hopena pōhaku paʻakikī i hoʻohālikelike ʻia ma o nā mīkini paʻi hydraulic—ʻaʻohe māwae, ʻaʻohe ʻāpana, ʻaʻohe hala ʻana. ʻO ia ke ʻano o ka hana lima e unuhi ʻia i ka hana maoli. Ma ka Powder River Basin o Wyoming, ʻo ia hoʻi, hoʻopuehu like ka mea ʻoki i ka ikaika hopena, e pale ana i ka hāʻule ʻino e hoʻopilikia ana i nā koho ʻē aʻe ʻoi aku ka maikaʻi. ʻAʻole wale ia he "hana maikaʻi"—ua kūkulu ʻia e ola i nā kūlana ʻino e kū nei i nā miners US i kēlā me kēia lā.
Hoʻolālā i kūkulu ʻia no ke kumu: Hoʻololi ka Conical Diamond Enhanced Compact i nā ʻano paʻakikī o ʻAmelika Hui Pū ʻIa
Ua ʻike nui ʻia ka ʻāina eli ʻana o ʻAmelika Hui Pū ʻIa he mea hoʻowahāwahā ʻole—mai ke one pōhaku ʻāwili o Utah a hiki i ka granite mānoanoa o Kaleponi, ke alo nei nā mea ʻoki i nā papa palupalu a paʻakikī e hoʻololi ana i ka hopena no nā huahana i hoʻolālā maikaʻi ʻole ʻia. ʻO ke ʻano tapered o ka conical diamond enhanced compact he mea hoʻololi pāʻani, i hana ʻia me nā ʻano US i ka noʻonoʻo. Mai kahi ʻano mechanical, hiki i ka hoʻolālā cone ke nahu koke i ka pōhaku, e hōʻemi ana i nā ukana hopena i hoʻopaʻa ʻia, ʻoiai ʻo ka mānoanoa o ka papa daimana i hoʻomaikaʻi ʻia e hoʻohui i kahi pale i hoʻoikaika ʻia ma kahi o ke kaumaha nui loa—he kikoʻī aʻu i hōʻoia ai i ka wā o nā hoʻokolohua kahua ma Arizona.
E lawe i nā hiʻohiʻona paʻa i hoʻonui ʻia i ka daimana Conical C3129 a me C0609, nā lio hana ma nā lua ʻeli ʻAmelika. Ma kahi lua pōhaku paʻakikī o Colorado, ua holo ka C3129 no 8 mau hola pololei me ka ʻole o ka hōʻino ʻia—hoʻohālikelike ʻia me 3 mau hola no nā mea ʻoki maʻamau. Ma kahi lua lanahu ma lalo o West Virginia, ua lawelawe ka C0609 i ka shale a me ka limestone ʻokoʻa, e hoʻonui ana i ke ola lawelawe ma 40% e hoʻohālikelike ʻia me nā DEC maʻamau. ʻAʻole kēia he ʻenekinia akamai wale nō; ua hoʻokumu ʻia ka hoʻolālā ma ka hoʻomaopopo ʻana i nā pilikia o ka lua ʻeli ʻana o ʻAmelika. No nā mea ʻeli ma aneʻi, ʻo ia hoʻi ka emi ʻana o ka manawa downtime, ka emi ʻana o nā pani, a me nā tone hou aʻe i neʻe ʻia—ʻo ia ka mea e pono ai mākou e noho hoʻokūkū.
Nā Hualoaʻa i Hōʻoia ʻia ma ke Kahua: Hoʻemi ka Conical Diamond Enhanced Compact i nā Kumukūʻai no nā Mines US
Ma ke ʻano he loea o ʻAmelika Hui Pū ʻIa, hoʻohiki wale wau ma nā huahana e hāʻawi ana ma kahi—a ua hala ka Conical diamond enhanced compact i ka hoʻāʻo ma mua o 30 mau mines ma ka ʻāina, mai nā kahua lanahu Appalachian a i nā mines metala Nevada. He ākea ka manaʻo: ʻoi aku ka maikaʻi o ka pale ʻana i ka hopena, emi ka hoʻololi ʻana, a me ka mālama kālā nui. Ua haʻi mai kekahi mea hana mine ma Texas iaʻu e hoʻololi i kēia huahana e hōʻemi i nā pani ʻokiʻoki mahina ma 6, hoʻonui i ka huahana lako ma 25%, a mālama i kahi kokoke i $300,000 i kēlā me kēia makahiki—nā helu e pili ana i ka ʻoihana mining US i hoʻokele ʻia e ka laina lalo.
Eia kekahi, hoʻokō ka mea hana i nā pono o ka mine US me nā kikoʻī hiki ke hoʻopilikino ʻia—19mm, 16mm, 13mm, a me nā nui maʻamau US ʻē aʻe, a me ka mānoanoa o ka papa daimana i hana ʻia no nā ʻano kikoʻī. I ka wā o nā kūkākūkā ma ka pūnaewele, ua ʻike kaʻu hui ʻo ka hoʻohui ʻana i ka huahana me nā alakaʻi hoʻonohonoho a ka mea hana (i hoʻomohala ʻia me nā lako US i ka noʻonoʻo) e hōʻemi ana i ka ʻōpala ukana hopena ma 30%. ʻO ia ke ʻano o ke kākoʻo kūpono e hoʻokaʻawale ai i ka Conical diamond enhanced compact—ʻaʻohe buzzwords, nā hoʻonā wale nō e hana no nā hana mining US.
I ka hana ʻeli ʻana ma ʻAmelika Hui Pū ʻIa, ʻaʻole ia he mea hoʻohiwahiwa ke kūʻē i ka hopena—he mea pono ia. Hāʻawi ka ʻāpana conical diamond i hoʻonui ʻia me ka hana lima i hōʻoia ʻia, ka hoʻolālā kikoʻī no ke kūkulu ʻana, a me nā hopena i kūpono i nā mea hana ʻeli. Inā luhi kāu ʻeli ʻana ma ʻAmelika Hui Pū ʻIa i nā hemahema pipiʻi o ka mea ʻoki a me ka manawa downtime, ʻaʻole kēia huahana he hoʻonui wale nō—he hoʻoholo ʻoihana akamai ia.
No nā kikoʻī hou aku e pili ana i ka Conical diamond enhanced compact a i ʻole e kūkākūkā i nā hoʻonā maʻamau no kāu hana mining US, e kelepona mai:
Ma hope o hoʻokahi ʻumi makahiki ma ka ʻoihana, kū wau ma ka ʻaoʻao o nā huahana e hana pono ana i ka wā e pono ai. Ua loaʻa i ka conical diamond enhanced compact kona wahi ma ke ʻano he lio hana hilinaʻi ma nā mines US, e hōʻoia ana e hiki i ka hana ʻana o ka honua ke hoʻokō a ʻoi aku ma mua o nā kūlana hana US. Eia nā mea ʻokiʻoki paʻakikī, nā hana maʻalahi, a me nā kumukūʻai haʻahaʻa—kahi mea e hiki i kēlā me kēia mea hana mines US ke kākoʻo.

E hahai mai iā mākou
No nā nīnau e pili ana i kā mākou huahana a i ʻole ka papa inoa kumukūʻai, e ʻoluʻolu e waiho i kāu leka uila iā mākou a e hoʻopili mākou i loko o 24 mau hola.
