I-PLATO DTH imingxunya yokuvula imingxuma inokubonelela ngokwandiswa komngxuma kwiimfuno ezahlukeneyo zesicelo sokomba isando esisezantsi, izizathu ezisusela kwi-drilling rig kunye nezixhobo zokusebenza ukuya kwimeko yendawo yokusebenza kunye neenkcukacha zomsebenzi. Ukongeza, ii-Acedrills' hole openers ziyafumaneka kwiindlela ezahlukeneyo zoyilo, nganye kuzo inokulungela kakhulu usetyenziso oluthile. Esi sixhobo siqhele ukusetyenziswa kushishino ukwenza imingxunya emikhulu kakhulu.

Imingxunya evula imingxunya ngamasuntswana okomba akhethekileyo anokuthi asetyenziswe ukwenza banzi imingxuma esele ikhona. Kwimeko ethile yomsebenzi kunokuba yimfuneko ukwandisa ubungakanani bomngxuma owenziwe ngaphambili ukuya kububanzi obukhulu okanye ukugrumba imingxuma emikhulu. Iibhithi zokuvula umngxuma ziyilelwe ngokukodwa le njongo, eyindlela esebenzayo yokwandisa imingxuma, yiloo nto amasuntswana abizwa ngokuba yi "Hole Opener". Isenzo esiqhelekileyo siquka ukugrumba umngxuma wokulingwa omncinane ngokwentelekiso kwinqanaba lokuqala, kwaye inqanaba lesibini nelokugqibela emva koko wandise ngakumbi ngeebhithi zokuvula umngxuma, kuba oku kunokukhokelela kumngxuma othe ngqo kwaye kufuna oomatshini abangenamandla kangako. Kwaye izigaba ezahlukeneyo zinokusetwa ngokweenkcukacha zokomba ukuze kwandiswe ukwaphuka nokususa, kunye nezakhono zokuriga. Ngaphandle koko, i-torque ejikelezayo, i-DTH yokuvula umngxuma ibandakanya amandla e-concussive achaphazela ngokuphindaphindiweyo intloko yokomba kwilitye okanye enye i-substrate. Isenzo sokuphembelela singacolisisa ilitye kwaye kwakhona alinyanzele ukuba libuye linyuke, linceda ukukhupha umngxuma wokutsala amanzi. Ke, ukongeza ekwandiseni umngxuma wokugqobhoza, isivula-mngxuma sinokucoca imathiriyeli engaphezulu kuyo.

Ukugrunjwa kwamaqula amakhulu kuyafuneka kwinani lamashishini ahlukeneyo, afana nokuhlola i-hydrocarbon, ukugrunjwa kwamaqula, kunye nokugrumba okuthe tyaba ukwenzela itonela kunye nezinye iinjongo njalo njalo. Ukugrumba umngxuma omnye omkhulu kunokufuna isixa samandla esikhethekileyo kunye noomatshini abakhulu kakhulu, ngoko ke inkqubo ngamanye amaxesha yenziwa ngamanyathelo amaninzi. Kwezinye iimeko, intwana encinci yobungakanani iya kusetyenziswa ukugrumba umngxuma wokulinga. Olu hlobo lokugrumba lufuna amandla amancinci kunokwenza kwinqanaba elinye kwaye lunokubangela umngxuma othe ngqo. Emva kokuba lo mngxuma wokuqala ugqojoziwe, indawo yokuvula umngxuma ingasetyenziselwa ukwandisa umngxuma wokutsala amanzi. Kwimeko enjalo, isiphumo sinokuba ngumngxuma wamanzi ochaneke ngakumbi owadalwa unezixhobo ezingenamandla kangako kunokuba bekuya kufuneka ukugrumba umngxuma omkhulu ekuqaleni ngokuthe ngqo.

Amasuntswana okuvula umngxuma wePLATO DTH ayafumaneka kwiidayamitha eziphindiweyo ukusuka kwi-130mm ukuya kwi-660mm (5 1/8” ukuya ku-26”) ngoyilo lwamashanki ukuze lulingane uninzi lweehamile ze-DTH ezidumileyo, kwaye zenziwe ngokweendlela ezininzi zoqwalaselo ukuhlangabezana nokugrunjwa kwendawo nganye. iimfuno. I-Acedrill isebenzisa kuphela eyona ntsimbi ifanelekileyo ekuveliseni imingxunya yayo yokuvula imingxunya, eya kukunika iyure emva kweyure yokugrumba okungenangxaki, kwaye kunye nabo uya kuhlala usazi ukuba yaveliswa ngomgangatho obuwulindele. Ukongeza, ii-Acedrills ziyakwazi ukusebenza nawe ukuyila intwana yokuvula umngxuma omtsha ukunyusa ukusebenza phantsi kweemeko zomhlaba ojongene nazo emsebenzini wakho ukuba kuyimfuneko.

I-PLATO ikwimeko yokubonelela abathengi ngamacandelo apheleleyo oluhlu lwezixhobo zokomba ze-DTH, kubandakanywa izando ze-DTH, amasuntswana (okanye izixhobo zokusebenza ezilinganayo), ii-adapter ezisezantsi, imibhobho yokubhobhoza (iintonga, iityhubhu), izando ze-RC kunye namasuntswana, i-drill-udonga olumbini. imibhobho kunye neebhentshi zokuqhawula isando njalo njalo. Izixhobo zethu zoKwemba i-DTH zikwayilwe kakuhle kwaye zenzelwe imigodi, imizi-mveliso yokomba amanzi, uphononongo, ulwakhiwo kunye nobunjineli boluntu.

EzantsiIndlela ye-Hole (DTH) yaphuhliswa ekuqaleni ukugrumba imingxunya enobubanzi obukhulu ezantsi kwizicelo zokugrumba umphezulu, kwaye igama layo lisuka kwinto yokuba i-percussion mechanism (isando se-DTH) ilandela isuntswana ngoko nangoko ukuya ezantsi emngxunyeni, endaweni yoko. ngaphezu kokuhlala kwi-feed njengama-drifters aqhelekileyo kunye nama-jackhammers.

Kwinkqubo yokugaya i-DTH, isando kunye ne-bit yinkqubo esisiseko kunye namacandelo, kwaye isando sifumaneka ngokuthe ngqo emva kwe-drill bit kwaye sisebenza phantsi komngxuma. I-piston ibetha ngokuthe ngqo umphezulu wempembelelo ye-bit, ngelixa i-hammer casing inika isikhokelo esithe ngqo nesizinzileyo se-drill bit. Oku kuthetha ukuba akukho mandla empembelelo aphumayo kuwo nawaphi na amalungu kuwo wonke umtya wokubhola. Amandla empembelelo kunye nezinga lokungena ke ngoko lihlala lingatshintshi, kungakhathaliseki ubunzulu bomngxuma. I-drill piston inikwe amandla ngumoya ocinezelweyo ohanjiswe ngeentonga kuxinzelelo lonikezelo olusuka ngokuqhelekileyo ukusuka kwi-5-25 bar (0.5-2.5 MPa / 70-360 PSI). I-pneumatic okanye i-hydraulic motor elula efakwe kwi-surface rig ivelisa ukujikeleza, kwaye ukugungxula ukusikwa kufezekiswa ngokuphuma komoya ophuma kwihamile mhlawumbi ngomoya oxinzelelweyo ngenaliti yenkungu yamanzi okanye ngomoya oqhelekileyo womgodi kunye nomqokeleli wothuli.

Imibhobho yokucoca idlulisela amandla okutya ayimfuneko kunye netorque ejikelezayo kwindlela yempembelelo (isando) kunye nesuntswana, kunye nokuhambisa umoya ocinezelweyo wehamile kunye nezisikwa ezigungxulwayo ngokuthi umoya wokukhupha uvuthulule umngxuma kwaye uwucoce kwaye uthwala izisikwa phezulu. umngxuma. Imibhobho yokomba yongezwa kumtya wokubhola ngokulandelelanayo emva kwehamile njengoko umngxuma uya usiba nzulu.

I-DTH yokugrumba yindlela elula kakhulu yabasebenzi yokomba umngxuma onzulu kunye othe ngqo. Kuluhlu lomngxuma oluyi-100-254 mm (4” ~ 10”), ukugrumba i-DTH yeyona ndlela ibalaseleyo yokugrumba namhlanje (ingakumbi xa ubunzulu bomngxuma bukhulu kuneemitha ezingama-20).

Indlela yokugaya i-DTH ikhula ekuthandeni, kunye nokunyuka kuzo zonke iinxalenye zesicelo, kubandakanywa ukuqhuma-umngxuma, umthombo wamanzi, isiseko, i-oyile kunye negesi, iinkqubo zokupholisa kunye nokugrumba iimpompo zokutshintsha ubushushu. Kwaye kwafunyanwa izicelo kamva zangaphantsi komhlaba, apho isalathiso sokomba siqhele ukubheka phezulu endaweni yokuya ezantsi.

Ezona mpawu ziphambili kunye neengenelo zokugrumba i-DTH (ngokukodwa thelekisa nokugrumba ngehamile ephezulu):

1.Uluhlu olubanzi lweesayizi zemingxuma, kubandakanywa nobukhulu bomngxuma omkhulu kakhulu;

2.Umngxunya ogqwesileyo wokuthe tye ngaphakathi kwe-1.5% ukutenxa ngaphandle kwezixhobo ezikhokelayo, zichaneke ngakumbi kunesando esiphezulu, ngenxa yempembelelo esemngxunyeni;

3.Ukucocwa komngxuma okulungileyo, kunomoya omninzi wokucoca umngxuma kwihamile;

4.Umgangatho omhle womngxuma, kunye neendonga ezigudileyo kunye nemingxuma yokutshaja lula kweziqhushumbisi;

5.Ukulula kokusebenza kunye nokugcinwa;

6.Ukuhanjiswa kwamandla okusebenzayo kunye nomthamo onzulu wokugaya umngxuma, kunye nokungena rhoqo kwaye akukho lahleko yamandla kumalungu ngokusebenzisa intambo yokubhobhoza ukusuka ekuqaleni ukuya ekupheleni komngxuma, njengehamile ephezulu;

I-7.Yenza i-debris encinci yokuxhoma, ukuqhawula okuncinci okwesibini, i-ore encinci yokudlula kunye ne-chute hang-ups;

8.Ixabiso eliphantsi kwizinto ezityiwayo ze-drill rod, ngenxa ye-drill string ayinyanzelwanga kunyanzeliso olunzima lwe-percussive njengoko kusembiwa kwehamile ephezulu kunye nobomi bomtya wokugrumba ngoko bandiswa kakhulu;

9. Ukunciphisa umngcipheko wokuxinga kwiimeko zamatye eziqhekekileyo kunye nezineziphene;

10.Inqanaba lengxolo ephantsi kwindawo yokusebenza, ngenxa yesando esisebenza phantsi komngxuma;

11.Amazinga okungena aphantse alingane ngokuthe ngqo kuxinzelelo lomoya, ngoko ke ukuphinda kabini uxinzelelo lomoya kuya kubangela ukuba kungene ngokuphindwe kabini.
