Phansi kwentengo ye-dth blast hole isando sokusabalalisa

Phansi kwembobo i-dth blast hole isando senani lokusabalalisa Isithombe esifakiwe

Incazelo emfushane:

Phansi kwamapayipi okubhoboza imbobo adlala indima ebalulekile kukho konke ukubhola kwe-DTH, kungakhathaliseki ukuthi asebenza ngaphi, uhlobo lwamadwala, ukujula kwembobo noma umshini wokubhoboza.Izici ezibalulekile zeshubhu ye-DTH yekhwalithi ephezulu ukuqina, ukunemba nokuphathwa.Amapayipi okubhoboza e-DTH enziwe nge-alloy ephakeme futhi zombili iziphetho zentambo ziyi-friction eshiselwe epayipini lensimbi elingenamthungo.Umoya ocindezelayo ophezulu ulethwa isando se-DTH ngepayipi lokubhoboza i-DTH, ngesikhathi esifanayo udlulisela ukuzungezisa nokucindezela amandla esando se-DTH.

Umlayezo I-imeyili

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

1) Ukungavimbi: Uchungechunge lwethu lwe-S Phansi izando zembobo zifakazelwa ukuze kuqinisekiswe izinga eliphansi kakhulu lokuvinjwa ngesikhathi lisebenza.

2) Ukusebenza Okuphakeme Kakhulu:Imishini yokumba umthombo ithwala amandla amakhulu okuvama komthelela kanye ne-torque, ngaleyo ndlela iqinisekise ukungena ngokushesha.Uma kuqhathaniswa nabanye, ukusebenza kahle kungathuthukiswa ngo-10%.

3) Impilo Yesevisi Ende: Zonke izindawo zesando se-DTH nezingcezu ziphathwa ngobuchwepheshe obunqanda ukungqubuzana nokuqina.Uma isetshenziswa emisebenzini yokumba i-deep-hole, ingafinyelela kumamitha angu-5000 noma ngaphezulu.

4) Umphumela Omuhle Kakhulu Wokuhlanza: Leli thuluzi le-DTH linokukhishwa komoya okukhulu, eliklanyelwe ngokukhethekile abasebenzisi bemithombo yamanzi futhi lenza likwazi ukukhipha ama-cuttings emisebenzini yokumba imigodi ejulile.

5) Isando sethu namabhithi kuyahambisana ne-DHD, QL ne-Mission isando namabhithi.
