DTH Drilling khoom

DTH sawv cev rau "Down-The-Hole," thiab DTH drilling cov khoom yog ib hom kev drilling cuab yeej siv nyob rau hauv ntau yam lag luam, xws li mining, kev tsim kho, thiab kev tshawb nrhiav roj. Cov khoom no yog tsim los tho qhov rau hauv av los yog pob zeb tsim los ntawm kev siv rauj.

 

Lub DTH drilling system muaj ib tug laum me ntsis, xyaum yeeb nkab, thiab ib tug percussion mechanism. Lub laum me ntsis yog cov cuab yeej txiav txuas mus rau qhov kawg ntawm cov yeeb nkab laum. Nws feem ntau muaj kev siv zog thiab ruaj khov los tiv thaiv lub zog thiab kev puas tsuaj thaum lub sij hawm drilling.

 

Txoj kev DTH drilling muaj xws li kev ua haujlwm rauj tsim los ntawm cov cua compressed los yog lwm yam kua dej, uas yog kis los ntawm cov yeeb nkab laum mus rau lub laum me ntsis. Qhov kev ua rau hammering pab ua kom cov pob zeb tsim los yog cov khoom siv hauv av nyuaj, thiab lub laum me ntsis txiav cov npoo nti tawm cov khoom tawg.

 

DTH drilling cov khoom muaj nyob rau hauv ntau yam kev tsim thiab kev teeb tsa kom haum rau cov kev xav tau sib txawv. Qee hom muaj xws li:

Khawm Cov Khoom: Cov khoom no muaj cov duab kheej kheej lossis hemispherical inserts ua los ntawm cov ntaub ntawv nyuaj xws li tungsten carbide. Lawv haum rau drilling los ntawm nruab nrab mus rau tawv pob zeb formations.

 

Hla Cov Khoom: Cov DTH drilling cov khoom no muaj ob lub kaum sab xis txiav uas sib tshuam ntawm qhov chaw, tsim cov duab ntoo khaub lig. Lawv feem ntau yog siv rau drilling hauv abrasive thiab tawg pob zeb formations.

 

Chisel Bits: Cov DTH drilling cov khoom no muaj lub tiaj, chisel-shaped txiav ntug. Lawv haum rau drilling hauv softer pob zeb formations thiab feem ntau yog siv rau lub hauv paus ua hauj lwm thiab hauv av consolidation.

 

Kauj Ruam Cov Khoom: Cov DTH drilling cov khoom no muaj cov kauj ruam profile nrog ntau qhov txiav. Lawv yog tsim los rau drilling nyob rau hauv ntau yam pob zeb formations, muab ceev nkag mus.

 

DTH drilling cov khoom paub txog lawv cov kev ua haujlwm siab drilling, kev hloov hluav taws xob zoo, thiab kev ua haujlwm zoo hauv kev tuav cov av sib txawv. Lawv tau siv dav hauv cov ntawv thov uas cov txheej txheem drilling cov qauv yuav tsis zoo lossis ua tau.

 

DTH (Down-The-Hole) drilling me ntsis yog siv nyob rau hauv ntau yam kev lag luam, xws li mining, kev tsim kho, thiab kev tshawb nrhiav hauv av. Cov khoom no raug hnav thiab tuaj yeem txhim kho qhov yuam kev thaum lub sijhawm. Nov yog qee qhov kev ua txhaum uas cuam tshuam nrog DTH drilling cov khoom thiab cov kev daws teeb meem los daws lawv:

1. Txo tus nqi nkag:
Ua tau: Hnav-tawm me ntsis, huab cua tsis txaus, dej ntws tsis txaus.

Kev daws teeb meem:
Hloov qhov hnav-tawm me ntsis nrog ib qho tshiab.
Xyuas kom meej tias huab cua siab nyob rau hauv qhov kev pom zoo.
Tshawb xyuas cov dej ntws tawm rau qhov thaiv thiab xyuas kom muaj kev tu kom zoo.

 

2. Bit Jamming:
Ua tau: Ntau dhau hnav lossis puas rau me ntsis, pob zeb wedging.
Kev daws teeb meem:
Hloov cov khoom puas nrog ib qho tshiab.
Xaiv qhov tsim me ntsis tsim nyog rau qhov tshwj xeeb drilling tej yam kev mob.
Kho qhov drilling tsis xws li kev sib hloov ceev thiab yaug kom txo tau pob zeb wedging.

 

3. Ntsis Bounce lossis Skating:
Ua tau: Tsis txaus qhov hnyav ntawm me ntsis, hnav-tawm lossis puas me ntsis, tsim pob zeb tsis sib xws.
Troublesootinhg:
Ua kom qhov hnyav ntawm me ntsis kom ntseeg tau tias muaj kev sib cuag nrog lub pob zeb tsim.
Hloov qhov hnav-tawm lossis puas me ntsis nrog ib qho tshiab.
Txheeb xyuas cov pob zeb tsim thiab kho qhov ntsuas qhov ntsuas kom haum
