Zosankha malasha ndi zida zofunika kwambiri pakukumba ndi migodi yosiyanasiyana:
Migodi Yamalasha Pansi Pansi: Choyambirira, chomwe chimagwiritsidwa ntchito kwa anthu ogwira ntchito m'migodi mosalekeza, ometa ubweya wautali, ndi otsogolera misewu.
Kutopetsa & Kuthamangitsidwa: Amagwiritsidwa ntchito pakupanga miyala yofewa kapena yolimba komanso yopangira migodi.
Kukumba kwa Trenching & Surface: Amagwiritsidwa ntchito pa ma trenchers ang'onoang'ono ndi okumba kuti azidula mu dothi lophatikizana ndi miyala yofewa.
Gome lotsatirali likufotokoza mwachidule zinthu zofunika kuziwona mwachangu:
| Mbali | Kufotokozera | Ubwino |
| Mutu Shape | Zoloza (conical) kapena ngati chisel. | Moyenera likulowerera ndi fractures zakuthupi. |
| Zakuthupi | Nsonga ya Tungsten carbide idalumikizidwa pathupi lolimba lachitsulo. | Amaphatikiza kukana kwambiri kuvala ndi kulimba kwamphamvu. |
| Core Mechanism | Kuzungulira kwaulere mkati mwa chotchinga chotsekedwa (kwa mitundu yambiri). | Imalimbikitsa ngakhale kuvala, kudzinola, komanso moyo wautali wautumiki. |
| Ntchito Yoyambira | Dulani ndikufukula malasha ndi mwala wofewa mpaka wapakati. | Zothandiza kwambiri pakuchotsa zinthu mwachangu mumigodi. |
| Phindu Lofunika Kwambiri | Kuchulukitsa Kuchita Mwachangu & Kuchepetsa Nthawi Yopuma. | Imasunga magwiridwe antchito, kuchepetsa kuchuluka kwa kusintha. |
| Common Applications | Ogwira ntchito m'migodi mosalekeza, ometa ubweya, oyendetsa misewu, makina opangira tunnel. | Chida chodulira chokhazikika chamigodi yamakono yamakina. |
Mwachidule, Zosankha Zamakala ndi zinthu zofunika kudyedwa mumakampani amigodi. Kapangidwe kawo kolimba, kuphatikiza nsonga yolimba ya tungsten carbide ndi thupi lolimba lachitsulo komanso makina ozungulira, zimatsimikizira zokolola zambiri komanso magwiridwe antchito pazovuta zapansi ndi pansi.
