1. Intshayelelo
I-Rotary drilling rig ngumatshini wokwakha ofanelekileyo kwimisebenzi yokugaya kwisiseko sobunjineli bokwakha. Kwiminyaka yakutshanje, iye yaba yeyona nto iphambili kulwakhiwo lwesiseko semfumba ekwakhiweni kwebhulorho eTshayina. Ngezixhobo ezahlukeneyo zokomba, i-rotary drilling rig ifanelekile kwimisebenzi yokomba kwindawo eyomileyo (i-spiral emfutshane), emanzi (ibhakethi ejikelezayo) kunye neengqimba zamatye (i-core drill). Ineempawu zamandla aphezulu afakiweyo, i-torque ephezulu ephumayo, uxinzelelo olukhulu lwe-axial, ukuguquguquka okuguquguqukayo, ukusebenza kakuhle kolwakhiwo kunye nokusebenza okuninzi. Amandla alinganisiweyo we-rotary drilling rig ngokubanzi yi-125-450kW, i-torque yokuphuma kwamandla yi-120-400kN•m, ubuninzi bomngxuma ububanzi bunokufikelela kwi-1.5-4m, kwaye ubunzulu bomngxuma ophezulu yi-60-90m, enokuthi ihlangabezane neemfuno zokwakhiwa kwesiseko esikhulu.
Kulwakhiwo lwebhulorho kwiindawo ezinobunzima bejoloji, iindlela zokwakha isiseko semfumba ezisetyenziswa ngokuqhelekileyo yindlela yemfumba yokwemba ngesandla kunye nendlela yokwemba impembelelo. Indlela yokwemba ngesandla iyapheliswa kancinci kancinci ngenxa yexesha elide lolwakhiwo lweziseko zemfumba, ubuchwephesha obuphelelwe lixesha, kunye nesidingo semisebenzi yokuqhushumba, ethi ibeke imingcipheko enkulu kunye neengozi; Kukwakho iingxaki ezithile ngokusebenzisa impembelelo yokugrumba kulwakhiwo, ikakhulu ebonakaliswa kwisantya esicothayo sokugrumba sempembelelo kwimigangatho yamatye aqinileyo ngokwejoloji, kunye nesenzeko sokungagrunjwa imini yonke. Ukuba i-geological karst iphuhliswe kakuhle, ukugrumba i-jamming ihlala isenzeka. Nje ukuba ukugrumba ukugrumba kwenzeke, ukwakhiwa kwemfumba egrunjiweyo kaninzi kuthatha iinyanga ezi-1-3, okanye nangaphezulu. Ukusetyenziswa kwezixhobo zokomba ezijikelezayo kulwakhiwo lwesiseko semfumba akuphuculi kakhulu kuphela isantya sokwakha nokunciphisa iindleko zokwakha, kodwa kukwabonisa ukongama okucacileyo kumgangatho wokwakha.
2. Iimpawu zeendlela zokwakha
2.1 Isantya sokwenziwa kwe pore
Ulungelelwaniso lwamazinyo kunye nolwakhiwo lwe-rock core drill bit ye-rotary drilling rig iyilwe ngokusekelwe kwithiyori yokuqhekeka kwamatye. Inokugrumba ngokuthe ngqo kumqolo wamatye, okukhokelela kwisantya esikhawulezayo sokomba kwaye iphucule kakhulu impumelelo yolwakhiwo.
2.2 Iinzuzo ezibalaseleyo kulawulo lomgangatho
Izixhobo zokomba ezijikelezayo zixhotyiswe ngokubanzi ngomngxuma omalunga neemitha ezi-2 (ezinokwandiswa ukuba umhlaba wokuzalisa ngasemva kumngxunya ungqindilili), kwaye i-rig ngokwayo inokushumeka i-casing, enokunciphisa impembelelo yomhlaba wokuzalisa ngasemva emngxunyeni. kwimfumba eyombiweyo; Umbhobho ojikelezayo wamkela umjelo ovuthiweyo ongaphantsi kwamanzi ogalela inkqubo yokugalela imfumba yekhonkrithi, enokuthi ithintele iziphumo ezibi zodaka oluwa kumngxuma kunye nentlenga eyenziwe ngexesha lokugalelwa; I-Rotary drilling rig ngumatshini wokwakha isiseko semfumba odibanisa isayensi kunye nobuchwepheshe bale mihla. Ngexesha lenkqubo yokugrumba, inokuchaneka okuphezulu kwi-verticality, ukuhlolwa kwe-rock layer ezantsi komngxuma, kunye nokulawula ubude bemfumba. Ngelo xesha, ngenxa yexabiso elincinci le-sediment ephantsi komngxuma, kulula ukucoca umngxuma, ngoko umgangatho wokwakhiwa kwesiseko semfumba uqinisekisiwe ngokupheleleyo.
2.3 Ukuziqhelanisa okuqinileyo nokwakheka komhlaba
Isixhobo sokomba esijikelezayo sixhotyiswe ngamasuntswana okomba awohlukeneyo, anokusetyenziswa kwiimeko ezahlukeneyo zejoloji ezifana neeleya zesanti, iileya zomhlaba, igrabile, iileya zamatye, njl. njl., ngaphandle kwemida yejografi.
2.4 Ukushukumiseka okufanelekileyo kunye nokuguquguquka okuqinileyo
I-chassis ye-rotary drilling rig ithatha i-crawler excavator chassis, ekwazi ukuzihambela yodwa. Ukongezelela, i-rotary drilling rigs inokusebenza ngokuzimeleyo, ibe nokuhamba okuqinileyo, ukulungelelanisa nomhlaba onzima, kwaye ayifuni izixhobo ezincedisayo zokufakela kunye nokuchithwa. Bahlala kwindawo encinci kwaye banokusebenza kwiindonga.
2.5 Ukhuseleko lokusingqongileyo kunye nokucoceka kwendawo yokwakha
Isixhobo sokomba esijikelezayo sinokusebenza kumatye akhiwe ngaphandle kodaka, nto leyo enganciphisi nje kuphela inkcitho yobutyebi bamanzi kodwa ikwathintela nokungcoliswa kwendalo engqongileyo okubangelwa ludaka. Ke ngoko, indawo yokwakha yerotary drilling rig icocekile kwaye ibangela ukungcoliseka okuncinci kokusingqongileyo.
3. Ubungakanani besicelo
Le ndlela yolwakhiwo ifanelekile ikakhulu kwiimfumba zokomba ngoomatshini bokubhola be-rotary ngendlela ephakathi kunye nebuthathaka ephantsi kolwakhiwo lwamatye kunye nomgangatho wamatye aqinileyo.
4. Umgaqo wenkqubo
4.1 Imigaqo yoYilo
Ngokusekwe kumgaqo wokusebenza wokugrumba i-rotary drilling rig, kudityaniswe neempawu zobuchwephesha bamatye kunye nethiyori esisiseko yokuqhekeka kwamatye ngokucolwa ngokujikelezayo, iimfumba zovavanyo zombiwa ngendlela ephakathi kunye nolwalwa oluqinileyo. Imilinganiselo yobugcisa efanelekileyo kunye nezalathi zezoqoqosho zeenkqubo ezahlukeneyo zokomba ezisetyenziswa yi-rotary drilling rig zahlalutywa ngokweenkcukacha-manani. Ngothelekiso nocazululo olucwangcisiweyo lobugcisa noqoqosho, indlela yolwakhiwo lweemfumba zokomba ezijikelezayo kulwakhiwo lwelitye lekalika olunobume obuphakathi kunye namatye aqinileyo ekugqibeleni yamiselwa.
4.2 Umgaqo-siseko wobuchwephesha bokugrumba kwi-rotary drilling rig kwi-formations yamatye
Ngokuxhobisa i-rotary drilling rig eneentlobo ezahlukeneyo zamasuntswana e-drill ukwenza ukwandiswa komngxuma ohleliweyo kulwakhiwo oluqinileyo lwamatye, indawo ekhululekileyo ezantsi komngxuma yenzelwe i-rotary drilling rig drill bit, iphucula isakhono sokungena kwelitye lokugrumba okujikelezayo. i-rig kwaye ekugqibeleni kuphunyezwe ukungena okusebenzayo kwamatye ngelixa kugcinwe iindleko zokwakha.
