Khoom Description LEANOS
DTH (Down-The-Hole) lub nplhaib ntiv nplhaib yog ib hom tshwj xeeb ntawm cov cuab yeej drilling siv hauv cov mining, kev tsim kho, thiab roj thiab roj kev lag luam rau drilling boreholes thiab qhov dej. Nws yog ib qho tseem ceeb ntawm DTH drilling system, uas yog percussive drilling txoj kev.
Khoom Description LEANOS
Daim ntawv thov LEANOS
DTH (Down-The-Hole) yas nplhaib khoom yog ntau yam cuab yeej drilling tsim los siv rau hauv ntau qhov chaw thiab tsim geological. Lawv feem ntau ua hauj lwm nyob rau hauv cov nram qab no hom terrains thiab geological tej yam kev mob:
Hard Rock Formations: DTH yas nplhaib cov khoom siv tau zoo heev rau kev drilling hauv cov pob zeb nyuaj xws li granite, basalt, limestone, thiab lwm cov pob zeb ntom ntom thiab abrasive. Lawv cov tungsten carbide txiav cov ntsiab lus tuaj yeem cuam tshuam los ntawm cov ntaub ntawv nyuaj.
Soft Rock Formations: Cov khoom no tuaj yeem siv rau hauv cov pob zeb softer xws li sandstone thiab shale. Cov ntsiab lus txiav ntawm lub nplhaib lub nplhaib tuaj yeem raug kho kom haum rau qhov tshwj xeeb hardness ntawm pob zeb.
Overburden Drilling: DTH drilling nrog lub nplhaib nplhaib feem ntau yog siv rau overburden drilling hauv mining thiab kev tsim kho cov haujlwm. Overburden hais txog cov khoom siv xoob lossis tsis sib koom ua ke npog cov pob zeb, thiab DTH cov khoom tuaj yeem nkag mus thiab tshem tawm cov khoom no kom ncav cuag lub hauv paus pob zeb lossis pob zeb hauv av.
Conglomerate Formations: DTH yas nplhaib cov khoom tuaj yeem tawg los ntawm kev sib koom ua ke, uas muaj cov pob zeb sib npaug ntawm cov khoom sib xyaw ua ke.
Hardpan thiab Caliche: Nyob rau hauv cov cheeb tsam arid, qhov twg hardpan khaubncaws sab nraud povtseg los yog caliche (ib hardened txheej ntawm calcium carbonate) yog tam sim no, DTH drilling yog ua hauj lwm los mus rau nkag mus thiab tawg cov txheej txheem nyuaj.
Geothermal Drilling: DTH yas nplhaib cov khoom siv nyob rau hauv geothermal drilling kom nkag mus rau hauv cov dej kub hauv av nyob tob hauv lub ntiaj teb lub pob zeb, feem ntau hauv cov pob zeb nyuaj.
Dej qhov dej: Cov khoom no feem ntau yog siv rau qhov dej drilling, qhov chaw uas lawv tuaj yeem nkag mus rau ntau yam geological tsim kom nkag mus rau hauv av. DTH drilling yog tshwj xeeb tshaj yog pab tau mus txog qhov tob aquifers.
Mineral Exploration: DTH yas nplhaib cov khoom siv dav siv hauv kev tshawb nrhiav pob zeb hauv av los sau cov qauv ntawm cov qauv sib txawv, suav nrog ob hom pob zeb tawv thiab mos.
Foundation Drilling: Hauv kev tsim kho, DTH drilling yog siv rau kev ua haujlwm hauv lub hauv paus, suav nrog qhov drilling qhov rau piling thiab anchoring hauv ntau hom av thiab pob zeb.
Kev Tshawb Fawb Roj thiab Roj: DTH drilling yog ua hauj lwm nyob rau hauv cov roj thiab roj kev tshawb nrhiav kom ncav cuag thiab qauv subsurface formations rau muaj hydrocarbons. Nws tuaj yeem tswj tau ntau yam ntawm geological tej yam kev mob ntsib hauv kev lag luam no.
