Ukubhola nge-DTH: Ukuguqula amashishini eMigodi noKwakha

Kwihlabathi eliguqukayo lobuchwepheshe bokugrumba, ukugrumba kwe-DTH (Down The Hole) kufumana ingqwalasela enkulu ngokusebenza kwayo kakuhle nangokusebenza kwayo, ngakumbi kumashishini afana nemigodi, ulwakhiwo, kunye nomsebenzi we-geotechnical. Le ndlela, esebenzisa isando kunye ne-bit ukugrumba ngqo emhlabeni, iye yaba yinto etshintsha umdlalo, inceda iinkampani ukuba zifumane iziphumo zokugrumba ezinzulu, ezikhawulezayo nezichanekileyo. Nantsi ingqwalasela enzulu yentoUkubhola nge-DTHyiyo loo nto, kutheni ibaluleke kangaka, kwaye iguqula njani amashishini kwihlabathi liphela.

Yintoni i-DTH Drilling?

Ukubhola nge-DTH (Down The Hole) kubhekisa kwindlela yokubhola apho ihamile kunye ne-bit zifumaneka ekupheleni komtya wokubhola, okanye "ezantsi komngxuma," ngqo kwi-drill bit. Ngokungafaniyo nokubhola okujikelezayo okuqhelekileyo, apho i-drill bit ijikeleziswa yi-surface motor,Ukubhola nge-DTHisebenzisa isando esinamandla esisebenza ngomoya esibetha umphezulu welitye ngamandla amakhulu, siwaqhekeza abe ziingceba ezincinci. Iingceba eziphumayo emva koko zisuswa lulwelo olujikelezayo, oludla ngokucinezelwa ngumoya okanye ngamanzi.

Le ndlela isebenza kakhulu ekugrumbeni amatye aqinileyo narhabaxa, apho ezinye iindlela zinokuba nzima ukugcina isantya okanye ukuchaneka.Ukubhola nge-DTHisetyenziswa rhoqo kwizicelo ezifana nezi:

• Ukwemba: Kwemigodi yokuqhuma kwimisebenzi yokwemba.
• Ulwakhiwo: Ukudala iziseko kunye nemingxunya yokuxhasa izakhiwo ezinzima.
• Amanzi eMithombo: Ukufikelela emanzini angaphantsi komhlaba kwiindawo ezinejoloji enzima.
