Inkcazelo emfutshane:

I-DTH drill rod/ibhobho yokomba uxinzelelo oluphezulu lokugrumba, ukugrunjwa kwequla lamanzi, imigodi.

Umyalezo I-imeyile

Iinkcukacha zeMveliso

Iithegi zeMveliso

Umbhobho wokugrumba, uhlobo olufutshane lombhobho wokugrumba umngxuma, luhlobo lwentonga yokomba engaphandle.Isetyenziswa ikakhulu kwi-rotary percussive drilling equlethe iigesi kunye nolwelo.Amacandelo ayo aphambili abandakanya umbhobho (intonga) umzimba kunye nokudibanisa.

Eyethu phantsi kombhobho wokubhobhoza umngxuma wenziwe ngokusekelwe kwimigangatho ye-API.Kwaye ngokweemfuno ezithile, sikwabonelela ngolu hlobo lombhobho wokubhola kwiinkcukacha ezahlukeneyo zesiTshayina kunye neMelika.

Ngokubhekiselele kwizinto eziluncedo, ineempawu zokuqina okukhulu, amandla okutywina okulungileyo, ulwakhiwo lwangaphandle olusicaba, kunye netorque ephantsi kunye nokumelana xa ujikeleza.

Ngokuphathelele ukupakishwa, inyanda yemibhobho yokubhobhoza iya kupakishwa ngeseti enye yesakhelo sentsimbi, kwaye inyanda iya kuba nemibhobho yokubhobhoza eyi-9 ukuya kwengama-40.

Izinto eziluhlaza: Umbhobho oshushu waqengqeleka ongenamthungo, osuka kwi-BAO STEEL/TPCO/BAO GANG njalo njalo, Ngokungqongqo ngokuhambelana nokuhlolwa kwemigangatho efanelekileyo, ngeplanti yokuvelisa, iplanti yokucubungula kabini, ukuqinisekisa umgangatho wezinto ezikrwada.
