Kukonza Kukana Kukhudzidwa ndi Kudula Migodi: Katswiri wa Zaka 10 wa ku US Apereka Umboni ku Magwiritsidwe Ntchito a Diamond Enhanced Compact (DEC)
Popeza ndakhala zaka khumi mumakampani obowola migodi ku US, ndawona mavuto ambiri chifukwa cha kukana kugwiritsa ntchito makina odulira miyala yolimba ku Colorado, nthawi zonse ndikagwira ntchito yosintha makina m'migodi ya malasha ku Texas, komanso kukwera mtengo kwa ntchito zomwe zimapangitsa oyang'anira migodi kukhumudwa. Koma masewerawa adasintha pamene ukadaulo wowonjezera diamondi (DEC) unakula, makamaka chifukwa cha kugwiritsa ntchito makina owonjezera a Conical diamondi. Monga munthu amene wakhala akugwiritsa ntchito migodi yapansi panthaka komanso m'malo opangira zinthu ku US konse, ndiloleni ndifotokoze momwe mankhwalawa asinthira kukana kugwiritsa ntchito makina odulira kuchokera pansi.
Ukadaulo Wotsimikizika: Msana wa Diamondi Yokhala ndi Koni Yowonjezera Mphamvu ya Compact
Mu gawo la migodi ku US, timakhala ndi mawu akuti "palibe njira zachidule zogwirira ntchito" - ndipo diamondi yowonjezera ya Conical imagwira ntchito bwino. Chinsinsi cha kulimba kwake chili mu kupanga mosamala, komwe ndatsimikizira ndekha paulendo wa fakitale. Chofunika kwambiri pakulimbana ndi kugwedezeka kwa cutter ndi mgwirizano pakati pa diamondi layer ndi carbide substrate, chinthu chomwe ndayesa mobwerezabwereza. Chogulitsachi chimagwiritsa ntchito ukadaulo wa polycrystalline diamond compact core, wokhala ndi kutentha kwa pressure ndi pressure zomwe zimayesedwa mpaka magawo a digiri ndi psi - chinthu chomwe US imachifuna kuti chikhale chogwirizana.
Kusankha zinthu zopangira n’kovuta kwambiri: kuyera kwa diamondi kufika pa 99.9%+, ndipo kuuma kwa carbide substrate kumayesedwa katatu ngati muyezo wa ASTM. Ndinaonanso njira yawo yowongolera khalidwe: gulu lililonse la diamondi yowonjezeredwa ya Conical diamondi limapirira kugwedezeka kwa miyala yolimba yoyeserera 5,000 kudzera mu makina osindikizira a hydraulic—popanda ming'alu, palibe tchipisi, kapena kudutsa. Umenewo ndi mtundu wa luso lomwe limamasulira magwiridwe antchito enieni. Mu Powder River Basin ku Wyoming, izi zikutanthauza kuti choduliracho chimagawa mphamvu yogunda mofanana, kupewa kulephera kwakukulu komwe kumakhudza njira zina zotsika mtengo. Sikuti "chopangidwa bwino" chokha - chimapangidwa kuti chipulumuke mikhalidwe yoopsa yomwe ogwira ntchito m'migodi aku US amakumana nayo tsiku ndi tsiku.
Kapangidwe Kopangidwa ndi Cholinga: Chopangidwa ndi Diamondi Yokhala ndi Ma Conical Yogwirizana ndi Mapangidwe Ovuta a US
Malo osungiramo migodi ku US amadziwika kuti ndi osakhululuka—kuyambira miyala ya mchenga ya ku Utah mpaka miyala yowirira ya ku California, odulira amakumana ndi zigawo zofewa komanso zolimba zomwe zimawonetsa mavuto kwa zinthu zopangidwa molakwika. Mawonekedwe ocheperako a diamondi yolumikizidwa bwino ndi conical ndi osintha kwambiri, opangidwa poganizira mapangidwe aku US. Kuchokera kumalingaliro amakina, kapangidwe ka cone kamalola wodulira kuluma mwala mwachangu, kuchepetsa kuchuluka kwa mphamvu, pomwe makulidwe a diamondi okonzedwa bwino amawonjezera chishango cholimba pamalo ovuta kwambiri—chidziwitso chomwe ndinachitsimikizira panthawi yoyesa kumunda ku Arizona.
Tengani mitundu ya C3129 ndi C0609 Conical diamond compact enhanced, workhorses in US mines. Mu mgodi wa miyala yolimba ku Colorado, C3129 inagwira ntchito kwa maola 8 motsatizana popanda kuwonongeka—poyerekeza ndi maola atatu a odulira wamba. Mu mgodi wa malasha wapansi panthaka ku West Virginia, C0609 inali ndi shale ndi limestone, zomwe zinawonjezera moyo wa ntchito ndi 40% poyerekeza ndi ma DEC wamba. Izi sizongopanga mwanzeru zokha; kapangidwe kake kamachokera pakumvetsetsa zovuta za migodi ku US. Kwa ogwira ntchito m'migodi pano, izi zikutanthauza kuti nthawi yochepa yogwira ntchito, malo osinthira ochepa, ndi matani ambiri osunthidwa—ndi zomwe timafunikira kuti tipitirizebe kupikisana.
Zotsatira Zotsimikizika: Diamondi Yokhala ndi Ma Cone Owonjezera Yachepetsa Ndalama Zogulira Migodi ku US
Monga katswiri waku US, ndikulumbira zinthu zomwe zimagulitsidwa pamalopo—ndipo kampani yopangidwa ndi diamondi ya Conical yapambana mayesowa m'migodi yoposa 30 mdziko lonselo, kuyambira minda ya malasha ya Appalachian mpaka migodi yachitsulo ya Nevada. Ndemanga zake ndi zapadziko lonse: kukana kukhudzidwa bwino, kuchepetsa kusintha kwa zinthu, komanso kusunga ndalama zambiri. Wogwira ntchito m'migodi ku Texas anandiuza kuti ndisinthe kugwiritsa ntchito zinthuzi posintha zinthu zodulira mwezi uliwonse ndi 6, kukulitsa kupanga kwa zida ndi 25%, ndikusunga pafupifupi $300,000 pachaka—ziwerengero zomwe zimagwirizana ndi makampani opanga migodi aku US omwe ali ndi phindu lalikulu.
Kuphatikiza apo, wopanga amakwaniritsa zosowa za mgodi wa ku US pogwiritsa ntchito zinthu zomwe zingasinthidwe—19mm, 16mm, 13mm, ndi zina zomwe zili ku US, komanso makulidwe a diamondi okonzedwa kuti agwirizane ndi mapangidwe enaake. Pa zokambirana zomwe zikuchitika pamalopo, gulu langa linapeza kuti kuphatikiza chinthucho ndi malangizo a wopanga (opangidwa poganizira zida zaku US) kumachepetsa zinyalala zowononga ndi 30%. Umenewo ndi mtundu wa chithandizo chothandiza chomwe chimasiyanitsa diamondi ya Conical yowonjezeredwa—palibe mawu omveka bwino, koma mayankho omwe amagwira ntchito pa ntchito za migodi ku US.
Mu migodi ya ku US, kukana kugunda si chinthu chapamwamba—ndi chinthu chofunikira. Chopangidwa ndi diamondi yozungulira bwino chimapereka luso lodziwika bwino, kapangidwe kake kapadera, komanso zotsatira zake zomwe zimakopa ogwiritsa ntchito migodi. Ngati mgodi wanu waku US watopa ndi kulephera kwa kudula kokwera mtengo komanso nthawi yogwira ntchito, izi sizongowonjezera chabe—ndi chisankho chanzeru cha bizinesi.
Kuti mudziwe zambiri za kapangidwe kake ka diamondi kokhala ndi mawonekedwe a conical kapena kukambirana njira zothetsera mavuto omwe mumagwiritsa ntchito pogwira ntchito yanu yamigodi ku US, lemberani:
