Ka whakamahia nga paraka DTH mo te pupuhi poka keri rig me te hama DTH, te nuinga whakamahia i roto i Mining, Marble keri, poka keri me etahi atu kaupapa hanga.
Te tono o te hama DTH
1. Ko te roa o te ora o te drill: te mea koranu, me te roa o te whakamahi i te ora e pai ake ana i nga hua rite;
2. Te kaha o te keri keri: ko nga pihi keri he mau-aukati, kia noho koi tonu te keri, na reira ka pai ake te tere o te keri.
3. Ka tau te tere keri: ka waruhia te moka ka tapahia kia pakaru te toka.
4. He pai te mahi: He kaha te kakahu o te moka MSD, he pai te whakamarumaru o te diameter, ka taea te whakamahi pai i nga niho tapahi, ka taea te keri i nga mita.
5. Te whakamahi i te whānuitanga whanui: ko te mahi e whakaatu ana he pai te moka mo te toka warowaiha, te toka, te tioka, te toka uku,
te toka toka, te kirikiri me etahi atu mea ngohe me te maro (te 9-akomanga keri toka, keri toka maro), ka whakaritea ki te moka noa,
ina koa ko te keri i te toka 6-8 he tino nui te paanga.
E wha nga momo hoahoa kanohi mutunga mo nga paraire DTH pehanga hau nui: momo momo convex kanohi mutunga, momo rererangi kanohi mutunga, momo concave kanohi mutunga me te momo pokapū concave hohonu.Ko te carbide cimented te nuinga o te tango i nga niho poi, te niho puna, te tikanga tohatoha niho ranei e tiritiria ana e nga niho poi me nga niho puna.
Ko te DTH drill bit te nuinga e whakamahia ana i roto i te torotoro whenua, maina waro, tiaki wai me te hiko wai, huarahi nui, piriti, hanga aha atu.
Nga Painga Hammer DTH
1. Te tere keri tere me te iti o te kohi hau na te hanganga motuhake o roto.
2. Maeneene mahi me te roa o te ratonga na te kounga teitei o nga rauemi koranu maitai me te hangarau tukatuka matatau kua urutau.
3. He iti te tere o te raru me te ngawari ki te tiaki na te ngawari, te pono me te ngawari ki te whakaemi me te wetewete i te hanganga o roto o te hama.
4. He ngawari ki te wehe moka mai i te hama na te maha o nga miro e hono ana i te maaka me te rango o te hama.
5. Ka taea te whakawhiti ki te moka DTH me te paipa keri.
