Ukuqonda Izimiso Zemishini Yezando Nezicucu ze-DTH

Lapho umba amatshe aqinile,Izando ze-DTH (Down the Hole) nezinsimbi zokubhoboza dlala indima ebalulekile enqubweni yokumba. Lawa mathuluzi enzelwe ukudabula ngempumelelo amatshe aqinile futhi anikeze izixazululo ezingabizi kakhulu zezinhlelo zokusebenza zokumba ezihlukahlukene. Kule bhulogi, sizobhekisisa ukuthi kanjaniizando ze-down-the-hole nama-drill bitsumsebenzi kanye nokubaluleka kwawo embonini yokumba.

 Isando sembobo phansi nebhithisebenzani ndawonye ukwakha indlela enamandla yokumba.Isando se-DTH iyithuluzi lomthelela elisetshenziselwa ukuletha igalelo elinamandla ku-drill bit, ngaleyo ndlela kuphulwa ukwakheka kwedwala. I- impactor inamathiselwe phezulu kwentambo yokubhoboza, futhi uma ishaya i-drill bit, ikhiqiza amandla omthelela aphezulu adluliselwa endaweni yedwala. La mandla omthelela enza ukuthi i-drill bit ingene edwaleni futhi yakhe imbobo.

Ama-influencer angaphansi kwembobo asebenza ngokucindezela umoya noma okunye uketshezi lokumba (njengamanzi noma udaka) ukuze kunikwe amandla amandla. Njengoba umoya ocindezelweyo noma uketshezi lwehla entanjeni yokubhoboza, lungena ku- impactor bese ludala uchungechunge lwamagalelo asheshayo, anamandla. Lawa magalelo asebenza ngqo ku-drill bit, eyivumela ukuthi iphuke futhi iphule ukwakheka kwamadwala. Ukusebenza kahle kweisando somgodi ophansiilele ekhonweni layo lokuletha amandla angaguquki nanamandla aphezulu, okuyenza ifaneleke izimo zokumba eziyinselele.

I-drill bit, ngakolunye uhlangothi, iyisici esiyinhloko esisebenzisana ngokuqondile nokwakheka kwamadwala. Yakhelwe ngezinto ezingagugi njengama-carbide blade ukuze imelane nokuguga kokumba amatshe. I-drill bit inochungechunge lwezinkinobho noma amazinyo abekwe ngokucophelela ukuze enze isenzo sokusika lapho eshaywa ngesando. Lesi senzo sokusika, esihlanganiswe namandla omthelela wesando, sivumela i-drill bit ukuthi iphule kahle idwala futhi yakhe imbobo yobubanzi obufunekayo.

Enye yezinzuzo eziyinhloko ze-down-the-hole hammer kanye ne-drill bit systems yikhono lokugcina izimbobo zokumba ziqondile futhi zinembile, ngisho nasezindaweni zamatshe aqinile. Amandla omthelela aphezulu akhiqizwa i-impactor aqinisekisa ukuthi i-drill bit igcina izinga lokungena elingaguquki, okuholela ekubholani okushelelayo nokunembayo. Lokhu kubaluleke kakhulu ezicelweni ezifana nezimayini, ukwakhiwa kanye nokumbiwa kwe-geothermal, lapho ikhwalithi ye-borehole ibaluleke kakhulu empumelelweni yomklamo.

Ngaphezu kwalokho, amasistimu wesando se-DTH nama-drill bit ahlinzeka ngokuhlukahluka emisebenzini yokumba. Ingasetshenziswa ezinhlobonhlobo zokwakheka kwamadwala, okuhlanganisa ukubunjwa okuqinile nokunama-abrasive, lapho ezinye izindlela zokumba zingase zibe nzima ukuthola imiphumela oyifunayo. Lokhu kuguquguquka kwenza izando ezidonsela phansi nezimbobo zibe yizinqumo ezidumile zamaphrojekthi ahlukahlukene okumba, kusukela ekumbiweni kwemithombo yamanzi kuya ekuhloleni uwoyela negesi.

Ngamafuphi, izando eziphuma phansi kanye nezinsimbi zokubhoboza ziyingxenye ebalulekile yemboni yokumba, ehlinzeka ngezixazululo ezinamandla nezisebenzayo zokumba amatshe aqinile. Ikhono labo lokuletha amandla omthelela omkhulu, ukugcina ukunemba kokumba kanye nokunikeza ukuguquguquka okuhlukahlukene kubenza babe ithuluzi elibalulekile lezinhlelo zokusebenza ezihlukahlukene zokumba. Ukuqonda ukuthi izando ze-DTH nezinsimbi zokubhola zisebenza kanjani kusiza ukuqonda ukubaluleka kwazo emhlabeni wokumba kanye nendima yazo ekunqobeni izimo zokumba eziyinselele.
