Mitundu Yosiyanasiyana Ya Migodi Ndi Chitsime Chobowola

Migodi ndi pobowola zing'onozing'ono ndizobowola zomwe zimabowola ndikulowa mu miyala yofewa komanso yolimba. Amagwiritsidwa ntchito m'migodi, kubowola zitsime, kukumba miyala, kumanga tunnel, kumanga, kufufuza za geological, ndi kuphulitsa.

Tizilombo tobowola migodi ndi zitsime nthawi zambiri zimakhala ndi ulusi wolumikizana ndi chingwe chobowola ndi thupi lopanda kanthu lomwe madzi akubowola amazungulira. Madzi obowola amafunikira kuti achotse zodulidwazo, kuziziziritsa pang'ono, ndikukhazikitsa khoma labowolo. Mitundu ya nthiti zoboola zitsime ndi izi:

Ma tricone kapena ma roller bitsili ndi ma cones atatu, iliyonse ili ndi ngodya ya magazini yomwe imayikidwa kumtunda woyambira. Mbali ya magazini imasinthidwa molingana ndi kuuma kwa mapangidwe. Mano a msomali uliwonse amalumikizana wina ndi mnzake kuti adutse dothi lolimba. Pang'onopang'ono imayendetsedwa ndi kulemera-pa-bit (WOB) pamene imakokedwa ndi machitidwe ozungulira a mutu wa kubowola.

Zida za nyundo zapansi pa dzenje (DTH).amagwiritsidwa ntchito ndi nyundo za Down-the-hole pobowola mabowo kudzera mumitundu yambiri ya miyala. Molumikizana ndi nyundo za DTH, nyundo zobowola zidapangidwa ndi splined drive kuti zizizungulira pang'ono pansi. Ma bits a DTH ndi tizidutswa tapamutu tokhazikika tokhala ndi ma conical kapena chisel bit bits olumikizidwa mu matrix pafupi ndi mutu wa kubowola. Kapangidwe ka mutu wa kagawo kakang'ono kamakhala kowoneka bwino, kosalala, kapena kosalala.

Zithunzi za PDCzoyikapo polycrystalline diamondi compact (PDC) zitha kutchedwa PDC bits. Mosiyana ndi ma tricone bits, PDC kubowola bits ndi matupi amodzi opanda magawo osuntha ndipo amapangidwa kuti azikhala; chilichonse chimapangidwa m'nyumba kuti chigwire ntchito, kusasinthika komanso kudalirika. Sankhani Matrix kapena chitsulo champhamvu kwambiri kuti chigwirizane ndi ntchito zosiyanasiyana zobowola.

Zolemba za batanindizofanana ndi ma DTH bits amutu-okhazikika omwe amakhala ndi ma conical kapena chisel bit omwe amalumikizana ndi matrix pamutu wobowola. Kapangidwe ka mutu wa kagawo kakang'ono kamakhala kowoneka bwino, kosalala, kapena kosalala. Button bit ndiye chozungulira chonse chomwe chili choyenera pamiyala yolimba kwambiri, kubowola nyundo.

Zidutswa zopingasa ndi ma chisel bitsndizitsulo zokhazikika zomwe zimakhala ndi zitsulo zolimba kapena masamba a carbide. Ma chetchi amatanthauzidwa ndi tsamba limodzi pomwe zopingasa zimakhala ndi masamba awiri kapena kupitilira apo omwe amadutsa pakati pa  biti. Masambawo nthawi zambiri amapendekera kumtunda wodulira.
