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.

Indlela ephantsi komngxuma (DTH) yaphuhliswa ekuqaleni ukugrumba imingxunya enobubanzi obukhulu ezantsi kwizicelo zokugrumba umphezulu, kwaye igama layo lisuka kwinto yokuba indlela ye-percussion (ihamile ye-DTH) ilandela isuntswana ngoko nangoko ukuya ezantsi emngxunyeni. , kunokuhlala kwifidi njengee-drifters eziqhelekileyo kunye neejackhammers.

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.
