PLATO ili ndi mwayi wopatsa makasitomala zida zonse za zida zoboola za DTH, kuphatikiza nyundo za DTH, ma bits (kapena zida zofananira nazo), ma adapter ang'onoang'ono, mapaipi obowola (ndodo, machubu), nyundo za RC ndi ma bits, kubowola pakhoma pawiri. mapaipi ndi mabenchi ophulika nyundo ndi zina zotero. Zida zathu za DTH Drilling zidapangidwanso bwino ndikupangidwira migodi, mafakitale akubowola zitsime zamadzi, kufufuza, zomangamanga ndi zomangamanga.

Njira ya down-the-hole (DTH) poyambilira idapangidwa kuti ibowole mabowo akulu akulu pansi pobowola pamwamba, ndipo dzina lake lidachokera kuti makina a percussion (nyundo ya DTH) amatsata pang'ono pang'onopang'ono kulowa mu dzenje. , m'malo mopitirizabe ndi chakudya monga ma drifters wamba ndi jackhammers.

Mu DTH pobowola dongosolo, nyundo ndi pang'ono ndi ntchito zofunika ndi zigawo zikuluzikulu, ndipo nyundo ili molunjika kuseri kwa kubowola ndi ntchito pansi dzenje. Pisitoni imagunda molunjika pamalo ang'onoang'ono, pomwe choyikapo nyundo chimapereka chiwongolero chowongoka komanso chokhazikika pabowolo. Izi zikutanthawuza kuti palibe mphamvu yamphamvu yotayira kudzera m'malo olumikizirana mafupa onse mu chingwe chobowola. Mphamvu yamphamvu ndi kulowetsedwa kotero kumakhalabe kosalekeza, mosasamala kanthu za kuya kwa dzenje. Pistoni yobowola imayendetsedwa ndi mpweya woponderezedwa womwe umaperekedwa kudzera mu ndodo pakukakamiza koyambira kuyambira 5-25 bar (0.5-2.5 MPa / 70-360 PSI). Makina osavuta a pneumatic kapena hydraulic okwera pamwamba pa chowongolera amatulutsa kasinthasintha, ndipo kuduladula kumatheka ndi mpweya wotulutsa kuchokera ku nyundo mwina ndi mpweya woponderezedwa ndi jekeseni wamadzi amadzi kapena mpweya wamba wamba wokhala ndi chotolera fumbi.

Mapaipi obowola amatumiza mphamvu yofunikira ya chakudya ndi torque yozungulira kumakina okhudzidwa (nyundo) ndi pang'ono, komanso kutulutsa mpweya woponderezedwa wa nyundo ndi ma cuttings otulutsa kuti mpweya wotuluka uwombe dzenje ndikulitsuka ndikunyamula zodulidwazo. dzenje. Mapaipi obowola amawonjezedwa ku chingwe chobowola motsatizana kuseri kwa nyundo pamene dzenje likuzama.

Kubowola kwa DTH ndi njira yosavuta kwa ogwiritsa ntchito pobowola zakuya komanso zowongoka. M'dzenje la 100-254 mm (4" ~ 10"), pobowola DTH ndiyo njira yayikulu kwambiri yobowola masiku ano (makamaka ngati kuya kwa dzenje kukupitilira mamita 20).

Njira yobowola DTH ikukula kwambiri, ndikuwonjezeka kwa magawo onse ogwiritsira ntchito, kuphatikizapo kuphulika, chitsime cha madzi, maziko, mafuta & gasi, makina oziziritsa ndi kubowola mapampu osinthira kutentha. Ndipo mapulogalamu adapezeka mobisa, pomwe njira yoboola nthawi zambiri imakhala yokwera m'malo mopita pansi.

Zomwe zikuluzikulu ndi zabwino pakubowola kwa DTH (makamaka yerekezerani ndi kubowola nyundo):

1.Wide osiyanasiyana makulidwe mabowo, kuphatikizapo lalikulu kwambiri dzenje awiri;

2.Kuwongoka bwino kwa dzenje mkati mwa 1.5% kupatuka popanda zida zowongolera, zolondola kwambiri kuposa nyundo yapamwamba, chifukwa chakukhudzidwa komwe kumakhala mu dzenje;

3.Kuyeretsa bwino dzenje, ndi mpweya wambiri woyeretsa dzenje kuchokera ku nyundo;

4.Good dzenje khalidwe, ndi yosalala ndi ngakhale dzenje makoma kuti alipirire mosavuta za mabomba;

5.Kuphweka kwa ntchito ndi kukonza;

6.Kutumiza mphamvu zogwiritsira ntchito mphamvu ndikubowola dzenje lakuya, ndikulowa kosalekeza ndipo palibe kutaya mphamvu m'magulu kudzera mu chingwe chobowola kuyambira pachiyambi mpaka kumapeto kwa dzenje, monga ndi nyundo yapamwamba;

7.Amapanga pang'onopang'ono zinyalala, kusweka pang'ono kwachiwiri, kuchepa kwa ore ndi ma chute hang-ups;

8.Kutsika mtengo kwa zinthu zogwiritsira ntchito ndodo zobowola, chifukwa cha chingwe chobowola sichimagwedezeka ndi mphamvu yamphamvu monga kubowola nyundo ndi moyo wa zingwe zobowola zimatalikitsidwa kwambiri;

9.Kuchepetsa chiopsezo chokakamira pamiyala yosweka ndi yolakwika;

10.Kutsika kwa phokoso pamalo ogwirira ntchito, chifukwa cha nyundo yomwe ikugwira ntchito pansi pa dzenje;

11.Kulowa kwapakati kumakhala pafupifupi molingana mwachindunji ndi kuthamanga kwa mpweya, choncho kuwirikiza kawiri kuthamanga kwa mpweya kumapangitsa kuti pafupifupi kuwirikiza kawiri.
