Ungayinweba kanjani impilo yesevisi ye-DTH drill bit ngesikhathi sokumba imbobo ejulile

Ezinhlelo zokusebenza zokumba imigodi ejulile, izingcezu zokubhola ze-DTH azinciphisi nje kuphela izindleko zokumba kodwa futhi zithuthukisa ukusebenza kahle kokubhola. Izingcezu zokubhoboza ze-DTH zisebenza kahle kakhulu nempilo ende yesevisi, enezindlela ezimbili zesakhiwo: Izingcezu zomoya omaphakathi nophansi we-DTH kanye nezingcezu zomoya ophakeme we-DTH, ukuxazulula inkinga yesikhathi esifushane sokuphila se-drill bits ekwakhekeni kwamadwala aqinile futhi abuthakathaka kanye nokuzuza imiphumela emihle.

Ubunzima okuhlangatshezwana nabo ekubhobolweni kwemigodi ejulile imijikelezo emide yokwakha kanye nezindonga zama-borehole ezingazinzile. Ngokukhula kokujula kokumba, ukuzinza kwe-borehole kuncipha, okwenza izingozi ngaphakathi kwembobo zibe nokwenzeka kakhulu. Ukuphakamisa njalo nokwehliswa kwentambo yokubhoboza kwandisa umonakalo ezintini zokubhoboza. Ngakho-ke, ngokwezici zokwakha kanye nezimo zokumba imbobo ejulile, uma isikhathi eside isikhawu kanye nesithombe esibuyiswayo sokuphakanyiswa, kuba ngcono. Izingcezu zokubhoboza ze-DTH zingamathuluzi akhethekile okumba amatshe, ngakho-ke zidlala indima ebalulekile ekusetshenzisweni kokumba imigodi ejulile.

Ama-drill bits e-HFD DTH anezici zokusebenza kahle kakhulu nempilo ende yesevisi, angagcini nje ngokunweba isikhathi sokusebenza se-drill bit ngaphansi komthombo kodwa futhi anciphisa inani lemisebenzi yokuphakamisa nokwehlisa, ukufeza umgomo wokusampula okusheshayo, ukuhlangana. izidingo zokubhoboza i-deep-hole, ukunciphisa kakhulu isikhathi sokwakha, kanye nokuqhubekisela phambili ubuchwepheshe bokubhola ezingeni elisha.
