Isando se-Hydraulic DTH, i-hydraulic shock noma i-hydraulic hammer), umthwalo womthelela we-hydraulic impact rotary drilling device, ukusetshenziswa kwayo ngesikhathi sokumba iphampu yodaka kuhlanza ukunikezwa kwamandla kwedrayivu eqondile ye-hydraulic isando esinomthelela esando phezulu naphansi esibuyisela ukunyakaza [ 1], futhi ngokuqhubekayo sibeke imvamisa ethile yomthwalo womthelela kumathuluzi okumba aphansi, Ukuze kuzuzwe umthelela wokubhola okujikelezayo.
I-Hydraulic DTH drilling iyinguquko enkulu yokumba okuvamile okujikelezayo kanye nendlela entsha yokumba ngemva kokubhoboza idayimane lesimanje kanye nokubhola komoya.Kuwubuchwepheshe obusebenzayo bokubhola ukuxazulula inkinga yokusebenza kahle kokumba kanye nekhwalithi embi yokumba ye-hard rock kanye ne-rock strata eyinkimbinkimbi ngokusebenzisa kahle ubuthakathaka betshe eliqinile elinobukhazikhazi obukhulu namandla okugunda okuphansi.
Uma kuqhathaniswa nokubhola okujikelezayo okujwayelekile
, ukumba i-hydraulic DTH kunezinzuzo ezilandelayo:
(1) Asebenzise ngokugcwele amathuluzi asekelayo asendaweni futhi ngokuyisisekelo angazishintshi izinqubo ezikhona zokusebenza;
(2) Ngenxa yokuthi umfutho wephampu wephampu yodaka kulula ukufinyelela inani eliphakeme, ngakho isando se-hydraulic IYAHLANGANISA ekujuleni kwembobo enkulu;
(3) Ukwakheka kwetshe eliqinile kunokuguga okuphezulu kokumba;
(4) I-stratum ephukile akulula ukuyixhuma, futhi ubude bevidiyo bubuyiselwa;
(5) Yelula ukuphila kancane kancane;
(6) Yehlisa imbobo amandla oblique ngokwezinga elithile;
(7) Ukunciphisa ukusetshenziswa kwamandla kanye nokungcoliswa kwemvelo okuncane;
(8) Ukungesabi i-aquifer, ikhono eliqinile lokuvikela udonga;
(9) Kulula ukuyisebenzisa nokuyinakekela.
