Phantsi komngxuma (DTH) amasuntswana okugrumba yinkqubo ephucukileyo yokuguqula imisebenzi yokomba kwimizi-mveliso yezimayini kunye nolwakhiwo.Ezi bhithi zisebenza ngeendlela ezininzi, ezikwaziwa ngokuba zii-hammer bits, zisebenzisa ihamile ye-percussion eqhutywa ngumoya ekwincam yebit.Esi sando sikhupha izithonga ezinamandla kumtya wokubhola, ukuwuvumela ukuba ugqobhoze nakweyona ndlela inzima yamatye.
Olona ncedo luphambili lwe-DTH drilling bits kukunyusa izinga lokungena kwabo, ngakumbi kwiimeko zamatye aqinileyo.Ngokungafaniyo neendlela zakwantu, ezixhomekeke ekugrunjweni okujikelezayo okanye kwi-percussive, amasuntswana okomba e-DTH asebenzisa indibaniselwano yazo zombini, nto leyo evumela ukomba okusebenzayo nokukhawulezayo.Ukongeza, i-DTH drilling bits yenzelwe ukujamelana neendawo zokugaya ezinobunzima, kubandakanywa noxinzelelo oluphezulu kunye neemeko zokushisa eziphezulu, ezizenza zilungele uluhlu olubanzi lwezicelo.
Enye yeenzuzo eziphambili ze-DTH zokomba amasuntswana kukuguquguquka kwazo.Zingasetyenziselwa imisebenzi eyahlukeneyo, kubandakanya ukugrumba imingxunya, ukugrumba imveliso, ukugrumba ukuhlola, kunye nokumbiwa phantsi komhlaba.Oku kuguquguquka kubenza babe sisisombululo esinendleko kwiiprojekthi ezininzi ezahlukeneyo zokomba.
Ukwenziwa kweebhithi zokomba ze-DTH yinkqubo entsonkothileyo ebandakanya uyilo olucokisekileyo kunye nokwenziwa ngokuchanekileyo.Iibhithi zenziwe ngentsimbi ephezulu kunye nezixhobo ze-carbide, ezikhethwe ngokucokisekileyo kwaye ziphathwe ukuze kuqinisekiswe amandla aphezulu kunye nokuqina.Amasuntswana ke acutshungulwa ngononophelo ukuba acacise iinkcukacha, ukuqinisekisa umgangatho ongaguqukiyo kunye nokusebenza.
Ukusetyenziswa kweebhithi zokomba ze-DTH nazo zithe ngqo.Intwana idityaniswe ngokulula kumtya we-drill kwaye ithotywe emngxunyeni.Xa sele ikwindawo, ihamile ye-percussion ngaphakathi kwebit iyavuselelwa, kwaye inkqubo yokomba iyaqala.Isiphumo sisebenza kakuhle kakhulu sokomba esinokunceda ukonga ixesha kunye nemali.
Ngamafutshane, i-DTH drilling bits lutshintsho olutsha oluguqula ishishini lokomba.Ngamazinga abo okungena angenakulinganiswa, ukuguquguquka, kunye nokuqina, bakhawuleza babe sisisombululo kwiiprojekthi ezininzi zokomba.Njengoko imfuno yezisombululo zokomba ezisebenzayo nezinexabiso elithe kratya ziqhubeka zikhula, i-DTH drilling bits iqinisekile ukuba idlala indima ebaluleke kakhulu kumashishini emigodi kunye nokwakhiwa kwiminyaka ezayo.
