PLATO iri mumwanya wo guha abakiriya ibice byose byurwego rwibikoresho byo gucukura DTH, harimo inyundo za DTH, bits (cyangwa bits ibikoresho bihwanye) imiyoboro n'intebe zo kumena inyundo nibindi. Ibikoresho byacu byo gucukura DTH nabyo byateguwe neza kandi bikozwe mubucukuzi bwamabuye y'agaciro, inganda zicukura amazi, ubushakashatsi, ubwubatsi nubwubatsi.

Uburyo bwo kumanura umwobo (DTH) bwabanje gutunganywa kugirango bucukure umwobo munini wa diametre hepfo mu bikorwa byo gucukura hejuru, kandi izina ryayo ryaturutse ku kuba uburyo bwa percussion (inyundo ya DTH) bukurikira bito bikamanuka mu mwobo. , aho kuguma hamwe nibiryo nkabashoferi basanzwe na jackhammers.

Muri sisitemu yo gucukura DTH, inyundo na biti nibikorwa byibanze nibigize, kandi inyundo iherereye inyuma yinyuma ya biti kandi ikorera munsi yumwobo. Piston ikubita hejuru yubuso bwa biti, mugihe inyundo itanga icyerekezo kigororotse kandi gihamye cyimyitozo. Ibi bivuze ko nta ngaruka imbaraga zirekura zinyuze mubice byose mumurongo wimyitozo. Ingaruka zingufu nigipimo cyinjira rero ziguma zihoraho, tutitaye kuburebure bwumwobo. Piston ya drill ikoreshwa numwuka uhumeka utangwa unyuze mu nkoni ku gitutu cyo gutanga kiri hagati ya 5-25 (0.5-2.5 MPa / 70-360 PSI). Moteri yoroheje ya pneumatike cyangwa hydraulic yashyizwe hejuru yubutaka itanga kuzunguruka, kandi gutemagura ibintu bigerwaho numwuka uva mu nyundo haba n'umwuka uhumeka hamwe n'inshinge zatewe n'amazi cyangwa n'umwuka usanzwe wo mu kirombe hamwe n'ikusanyirizo ry'umukungugu.

Imiyoboro ya drill yohereza imbaraga zikenewe zo kugaburira hamwe no kuzunguruka kuri tike yuburyo bwo kugira ingaruka (inyundo) na biti, ndetse no gutanga umwuka ucometse ku nyundo no gukata amashanyarazi kubera ko umwuka wuzuye uhuha umwobo ukawusukura kandi ugatwara ibice hejuru. umwobo. Imiyoboro ya myitozo yongewe kumurongo wimyitozo ikurikiranye inyuma yinyundo uko umwobo ugera kure.

Gucukura DTH nuburyo bworoshye cyane kubakoresha kubucukuzi bwimbitse kandi bugororotse. Mu mwobo uri hagati ya mm 100-254 (4 ”~ 10”), gucukura DTH nuburyo bwiganje bwo gucukura muri iki gihe (cyane cyane iyo ubujyakuzimu burenze metero 20).

Uburyo bwa DTH bwo gucukura buragenda bwiyongera mubyamamare, hamwe no kwiyongera mubice byose byasabwe, harimo guturika-umwobo, iriba ryamazi, umusingi, peteroli na gaze, sisitemu yo gukonjesha no gucukura pompe zo guhanahana ubushyuhe. Kandi porogaramu yaje kuboneka kubutaka, aho icyerekezo cyo gucukura muri rusange kiri hejuru aho kumanuka.

Ibintu nyamukuru nibyiza byo gucukura DTH (cyane ugereranije no gucukura hejuru-inyundo):

1.Urugero runini rw'imyobo, harimo na diameter nini cyane;

2.Umwobo mwiza ugororotse muri 1.5% gutandukana udafite ibikoresho biyobora, byukuri kuruta inyundo yo hejuru, kubera ingaruka ziri mumwobo;

3.Gusukura umwobo mwiza, hamwe numwuka mwinshi wo koza umwobo ku nyundo;

4.Ubuziranenge bwumwobo, hamwe nurukuta rworoshye ndetse n’urwobo rwo kwishyuza byoroshye ibisasu;

5.Ubworoherane bwo gukora no kubungabunga;

6.Imbaraga zogukwirakwiza ingufu hamwe nubushobozi bwo gucukura umwobo muremure, hamwe no guhora byinjira kandi nta gutakaza ingufu mu ngingo zinyuze mu mugozi wimyitozo kuva itangira kugeza irangiye umwobo, kimwe ninyundo yo hejuru;

7.Kora imyanda mike kumanikwa, kumeneka kabiri, gucukura amabuye make na chute kumanikwa;

8.Ibiciro bito ku bikoresho bikoreshwa mu gucukura, kubera umugozi wimyitozo ntibikoreshwa ningufu ziremereye nkuko hamwe no gucukura inyundo zo hejuru hamwe nu mugozi wimyitozo rero biraramba cyane;

9.Kugabanya ibyago byo kugwa mumiterere yamabuye yamenetse kandi afite amakosa;

10.Urwego rwo hasi rw'urusaku ku kazi, kubera inyundo ikora munsi y'umwobo;

11.Ibipimo byinjira byinjira hafi yumuvuduko wumwuka, kubwibyo gukuba kabiri umuvuduko wumwuka bizavamo inshuro ebyiri kwinjira.
