Yiziphi izinhlobo zemishini yokumba ephansi?

I-down-the-hole rig, eyaziwa nangokuthi i-down-the-hole rig, iwuhlobo lwemishini yokumba esetshenziswa ezimbonini zezimayini, zokwakha, nezihlola uphethiloli.Lezi zinsimbi zenzelwe ukubhoboza imigodi emhlabathini ngokusebenzisa indlela efana nesando ukugqekeza idwala noma inhlabathi.Kunezinhlobo ezimbalwa zemishini yokumba imigodi engaphansi emakethe, ngayinye inezici zayo ezihlukile namandla ayo.Ngezansi kukhona ezinye izinhlobo ezijwayelekile zokubhoboza imbobo phansi.

1. Isiseshi sokumba imbobo phansi:
Lolu hlobo lwe-drilling rig lufakwe ku-crawler chassis futhi lungahanjiswa kalula endaweni emagebhugebhu.Ivamise ukusetjenziswa emisebenzini yezimayini neyokwakha lapho umnotho uqakatheke khulu.Imishini yokumba ama-Crawler down-the-hole ayaziwa ngokuzinza, ukuqina kanye nokusebenza kahle kokubhola.

2. Isisetshenziswa sokubhola se-DTH esifakwe emotweni:
Njengoba igama liphakamisa, lolu hlobo lokumba umgodi ophansi lufakwa elolini ukuze kube lula ukuhamba ukusuka kwenye indawo ukuya kwenye.Ngokuvamile isetshenziswa kumaphrojekthi wokwakhiwa komgwaqo nezinye izinhlelo zokusebenza ezidinga ukuhamba.Imishini yokumba i-DTH egibele ngeloli iyaziwa ngokuguquguquka nekhono lokumba imigodi ezinhlobonhlobo zenhlabathi namadwala.

3. Uhlobo lwe-trailer yokumba i-DTH:
Ngokufanayo nezinsimbi zokumba ze-DTH ezifakwe emotweni, izinsimbi zokumba ze-DTH ezifakwe nge-trailer zifakwe kuma-trailer ukuze zihambe kalula.Ijwayele ukusetshenziswa kumaphrojekthi amancane wokwakha kanye nokumbiwa kwemithombo yamanzi.Izinsimbi zokumba ezibekwe nge-trailer ezansi nomgodi zaziwa ngosayizi wazo ohlangene nokusebenza okulula.

4. Umshini wokumba ongasheleli phansi:
Amarigi okubhola e-DTH afakwe eskid afakwa kumabhulokhi wokushibilika ukuze anikeze ukuzinza ngesikhathi sokumba.Ivame ukusetshenziswa kumaphrojekthi we-geotechnical drilling kanye nemvelo yokumba.Amarigi okumba e-DTH afakwe eskid aziwa ngokuklama kwawo okuhlangene, ukufakwa kalula kanye nokunemba okuphezulu kokubhola.

5. Umshini wokumba ongaphansi komhlaba we-DTH:
Lolu hlobo lwe-drilling rig ye-down-the-hole yakhelwe ngokukhethekile imisebenzi yokumba ngaphansi komhlaba.Ivamise ukusetshenziswa kwezobunjiniyela bezimayini kanye nomhubhe, lapho ukubhola kuyadingeka ezindaweni ezivalekile.Izinsimbi zokumba ezingaphansi komhlaba ze-DTH zaziwa ngosayizi wazo ohlangene, ukuhleleka nokusebenza kahle ekubholeni ngaphansi kwezimo eziyinselele.

Ngamafuphi, kunezinhlobo ezahlukene zemishini yokumba imigodi ephansi emakethe, ngayinye yakhelwe izinhlelo zokusebenza nezidingo ezithile.Kungakhathaliseki ukuthi ukumba izimayini, ukwakhiwa noma ukuhlola uwoyela, ukukhetha uhlobo olulungile lwe-drilling rig ephansi kubalulekile ukuze kuqinisekiswe imisebenzi yokumba ephumelelayo nephumelelayo.
