1. Isandulelo
I-Rotary drilling rig ingumshini wokwakha ofanele imisebenzi yokumba ekwakheni ubunjiniyela besisekelo. Eminyakeni yamuva nje, sekuyiwona mandla amakhulu ekwakhiweni kwesisekelo senqwaba ekwakhiweni kwamabhuloho eChina. Ngamathuluzi okumba ahlukene, i-rotary drilling rig ifaneleka ekusebenzeni kokumba endaweni eyomile (i-short spiral), emanzi (ibhakede elijikelezayo) kanye nezingqimba zamatshe (i-core drill). Inezici zamandla afakiwe aphezulu, i-torque ephezulu ephumayo, ingcindezi enkulu ye-axial, i-flexible maneuverability, ukusebenza kahle okuphezulu kokwakhiwa kanye nokusebenza okuningi. Amandla alinganiselwe we-rotary drilling rig ngokuvamile angu-125-450kW, i-torque yamandla ephumayo ingu-120-400kN•m, ububanzi bembobo obukhulu bungafinyelela ku-1.5-4m, kanti ukujula kwembobo okuphezulu kungu-60-90m, okungahlangabezana nezidingo zokwakhiwa kwesisekelo esikhulu esihlukahlukene.
Ekwakhiweni kwamabhuloho ezindaweni eziqinile ngokwezwe, izindlela zokwakha isisekelo senqwaba ezivame ukusetshenziswa yindlela yenqwaba yokumba mathupha kanye nendlela yokumba umthelela. Indlela yokumba mathupha iyayekwa kancane kancane ngenxa yesikhathi eside sokwakhiwa kwezisekelo zenqwaba, ubuchwepheshe obuphelelwe yisikhathi, kanye nesidingo semisebenzi yokuqhumisa, okudala izingozi ezinkulu kanye nobungozi; Kukhona futhi nezinkinga ezithile zokusebenzisa imishini yokumba ukuze kwakhiwe, ebonakala kakhulu ngesivinini sokumba esinensa kakhulu sokubhoboza okunethonya kumatshe aqinile ngokwezwe, kanye nokwenzeka kokungambiwa usuku lonke. Uma i-karst ye-geological ithuthukiswe kahle, i-drilling jamming ivame ukwenzeka. Lapho nje ukubhoboza i-jamming kwenzeka, ukwakhiwa kwenqwaba eboshiwe ngokuvamile kuthatha izinyanga ezingu-1-3, noma ngisho nangaphezulu. Ukusetshenziswa kwama-rotary drilling rigs ekwakheni isisekelo senqwaba akugcini nje ngokuthuthukisa isivinini sokwakha futhi kunciphisa izindleko zokwakha, kodwa futhi kubonisa ukuphakama okusobala kwekhwalithi yokwakha.
2. Izici zezindlela zokwakha
2.1 Isivinini esisheshayo sokwakheka kwezimbotshana
Ukuhlelwa kwamazinyo kanye nesakhiwo se-rock core drill bit ye-rotary drilling rig yakhelwe ngokusekelwe kumbono wokuhlukaniswa kwamadwala. Ingakwazi ukubhoboza ngokuqondile ongqimbeni lwamadwala, okuholela esivinini sokumba ngokushesha futhi kube ngcono kakhulu ukusebenza kahle kokwakhiwa.
2.2 Izinzuzo ezivelele ekulawuleni izinga
Ama-Rotary drilling rigs ngokuvamile afakwe imbobo yembobo engaba amamitha angu-2 (enganwetshwa uma inhlabathi engemuva emgodini iwugqinsi), futhi i-rig ngokwayo ingashumeka i-casing, enganciphisa umthelela wenhlabathi yokubuyisela emuva emgodini. enqwabeni ebhoboziwe; I-Rotary drilling rig ithatha umsele ovuthiwe ongaphansi kwamanzi othela inqubo yokuthulula inqwaba kakhonkolo, engagwema imiphumela emibi yokuwa kodaka emgodini kanye nenhlabathi ekhiqizwa ngesikhathi sokuthulula; I-Rotary drilling rig iyimishini yokwakha isisekelo senqwaba ehlanganisa isayensi nobuchwepheshe besimanje. Phakathi nenqubo yokumba, inokunemba okuphezulu kokuma mpo, ukuhlolwa kongqimba lwamadwala ngaphansi komgodi, nokulawula ubude benqwaba. Ngesikhathi esifanayo, ngenxa yenani elincane le-sediment ngaphansi komgodi, kulula ukuhlanza umgodi, ngakho ikhwalithi yokwakhiwa kwesisekelo senqwaba iqinisekisiwe ngokugcwele.
2.3 Ukuzivumelanisa nezimo okuqinile ekubunjweni komhlaba
I-Rotary drilling rig ifakwe izingcezu zokubhola ezihlukene, ezingasetshenziselwa izimo ezehlukene zejoloji njengezingqimba zesihlabathi, izingqimba zenhlabathi, amatshe amatshe, izingqimba zamatshe, njll., ngaphandle kwemikhawulo yendawo.
2.4 Ukuhamba kalula kanye nokuguquguquka okuqinile
I-chassis ye-rotary drilling rig ithatha i-crawler excavator chassis, ekwazi ukuzihambela yodwa. Ukwengeza, ama-rotary drilling rigs angasebenza ngokuzimela, abe nokuhamba okuqinile, azivumelanise nendawo eyinkimbinkimbi, futhi ayidingi izinsiza ezisizayo zokufakwa nokuhlakazeka. Zithatha indawo encane futhi zingasebenza ngokumelene nezindonga.
2.5 Ukuvikelwa kwemvelo kanye nokuhlanzeka kwendawo yokwakha
I-Rotary drilling rig ingasebenza ekwakhekeni kwamadwala ngaphandle kodaka, okungagcini nje ngokunciphisa ukuchithwa kwemithombo yamanzi kodwa futhi egwema ukungcoliswa kwendawo ezungezile okubangelwa udaka. Ngakho-ke, indawo yokwakha ye-rotary drilling rig ihlanzekile futhi ibangela ukungcoliswa okuncane kwemvelo.
3. Ububanzi besicelo
Le ndlela yokwakha ifaneleka ngokuyinhloko izinqwaba zokumba ngemishini yokumba eyi-rotary ekwakhekeni kwamadwala anesimo sezulu esingesihle esinekhwalithi eqinile uma kuqhathaniswa.
4. Umgomo wenqubo
4.1 Izimiso Zokuklama
Ngokusekelwe esimisweni sokusebenza sokumba i-rotary drilling rig, kuhlanganiswe nezakhiwo zemishini zamatshe kanye nethiyori eyisisekelo yokuhlukaniswa kwamadwala ngokumba i-rotary drilling rig, izinqwaba zokuhlola zambiwa ekwakhekeni kwe-limestone enesimo sezulu esilinganiselwe ngamatshe aqinile uma kuqhathaniswa. Imingcele yezobuchwepheshe efanele kanye nezinkomba zezomnotho zezinqubo ezihlukene zokumba ezisetshenziswa i-rotary drilling rig zahlaziywa ngokwezibalo. Ngokuqhathanisa okuhlelekile kwezobuchwepheshe nezomnotho kanye nokuhlaziya, indlela yokwakha yezinqwaba zokumba izinsimbi ezijikelezayo ekwakhekeni kwe-limestone enesimo sezulu esilinganiselwe namatshe aqinile uma kuqhathaniswa yanqunywa.
4.2 Umgomo wobuchwepheshe bokubhola bomshini wokumba ojikelezayo ekwakhekeni kwamadwala
Ngokuhlomisa i-Rotary drilling rig enezinhlobo ezahlukene zokumba ukuze yenze imbobo ekhuliswe ngokwezinga ekwakhekeni kwamadwala aqinile, indawo ekhululekile ngaphansi kwembobo kwakhiwa insimbi yokubhola eyi-rotary, ethuthukisa ikhono lokungena edwaleni lokumba okujikelezayo. i-rig futhi ekugcineni izuze ukungena okusebenzayo kwamadwala ngenkathi yonga izindleko zokwakha.
