Nyob rau hauv kev loj hlob txuas ntxiv ntawm kev xav tau thoob ntiaj teb, cov khoom siv mining zoo thiab ruaj khov tau dhau los ua qhov tseem ceeb rau kev ua kom muaj zog thiab cov khoom siv ntxhia. Polycrystalline pob zeb diamond compact (PDC) cutters, nrog lawv cov kev ua tau zoo tshaj, yog maj mam hloov cov tsoos carbide cutters raws li ib feem tseem ceeb ntawm cov peev txheej extraction. Lawv cov txiaj ntsig tseem ceeb nyob hauv peb qhov tseem ceeb: kev siv thev naus laus zis, kev hloov kho tshwj xeeb, thiab kev tsim kho tshiab.

Los ntawm txoj kev xav, PDC cutters tau ua tiav quantum leap hauv hardness thiab hnav tsis kam. Synthesized nyob rau hauv qhov kub thiab txias siab los ntawm pob zeb diamond micro hmoov thiab carbide substrate, lawv tau txais lub siab tawv ntawm pob zeb diamond (tshaj HV10,000) thaum tuav cov kev cuam tshuam toughness ntawm carbide. Qhov no daws qhov teeb meem ntsib los ntawm cov tsoos cutters: siab hardness ua rau brittleness, thaum siab toughness ua rau hnav. Hauv kev sib sib zog nqus-shaft mining, PDC cutters, ua haujlwm hauv cov pob zeb nyuaj xws li granite thiab basalt, pom tus nqi hnav uas tsuas yog ib feem tsib ntawm cov carbide cutters, txuas lawv lub neej kev pabcuam los ntawm 3-5 zaug. Qhov no txo ​​qis qhov zaus ntawm cov khoom hloov pauv hauv av thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam cov mining. Nyob rau hauv cov nqe lus ntawm adaptability, versatility ntawm PDC cutters ua tau raws li ntau haiv neeg xav tau kev pab extraction. Nyob rau hauv cov roj thiab roj drilling, lawv cov ntse txiav ntug sai sai tsoo pob zeb formations. Customized hniav profiles (xws li cov npoo thiab daim duab diav) hloov mus rau qhov sib txawv ntawm qhov chaw zoo, ua kom cov drilling efficiency nyob rau hauv kab rov tav thiab kev taw qhia qhov dej ntau dua 40%. Nyob rau hauv cov thee mining, cuam tshuam-resistant PDC cutters tiv taus qhov cuam tshuam hnyav ntawm coal seam inclusions, tiv thaiv cov hniav puas thiab ua kom muaj kev ua haujlwm tsis tu ncua ntawm cov khoom siv mining tag nrho. Hauv cov hlau mining, PDC cutters nrog corrosion-resistant coatings tiv taus yaig los ntawm acidic mining dej, ua rau lawv haum rau ob qho tib si qhib-qhov thiab underground mining nyob rau hauv complex geological ib puag ncig.

Los ntawm kev xav txog kev lag luam, PDC cutters tau pab ncaj qha rau kev txo nqi thiab kev txhim kho kev siv peev txheej. Ntawm qhov tod tes, lawv lub neej ntev ntev txo tus nqi ntawm kev yuav khoom thiab hloov cov khoom siv. Piv txwv li, hauv cov roj drilling, tus nqi ntawm cov cutters ib qhov dej tuaj yeem raug txo los ntawm 20% -30%. Tsis tas li ntawd, lawv cov kev ua tau zoo txiav ua kom luv luv lub voj voog mining. Piv txwv li, tom qab siv PDC cutters, ib lub pob zeb loj loj tau nce nws cov shearer cov duab txhua hnub los ntawm 80 meters mus rau 120 meters, nce txhua xyoo muaj peev xwm los ntawm 15%. Tsis tas li ntawd, cov khoom siv qis qis ntawm PDC cutters txo qis kev tsim thiab ua kom yooj yim rau kev tu lub qhov dej, ua rau kev txhim kho kev nyab xeeb ntawm mining.

Raws li cov peev txheej extraction nce zuj zus thiab mus rau hauv ntau txoj kev tsim, thev naus laus zis hloov pauv ntawm PDC cutters txuas ntxiv mus. Nyob rau hauv lub neej yav tom ntej, los ntawm kev txhim kho qhov kub thiab txias los ntawm nano-txheej technology thiab optimizing lub cutter qauv los ntawm 3D luam ntawv, PDC cutters yuav ntxiv kov yeej cov kev ua tau zoo bottlenecks, muab kev txhawb zog rau txoj kev loj hlob ntawm nyuaj-rau-extract peev xwm xws li shale gas thiab dej hiav txwv sib sib zog nqus minerals, thiab ntxiv consolidating lawv txoj hauj lwm tseem ceeb nyob rau hauv cov kev pab cuam extraction.
