Zipangizo Zapamwamba
Kampaniyo yakhazikitsa nsanja yanzeru yoyang'anira zida, ndipo yakhazikitsa ma seti 310 a maloboti ogwirira ntchito ndi kuwotcherera. Dongosololi likatha, padzakhala ma seti opitilira 500 (ma seti), ndipo kuchuluka kwa maukonde a zida kudzafika 95%. Mizere 32 yowotcherera yagwiritsidwa ntchito, 50 ikukonzekera kuyikidwa, ndipo kuchuluka kwa makina odziyimira pawokha kwa mzere wonse wazinthu kwafika 85%.
Malo Ogwirira Ntchito Omwe Amapangidwa ndi Magirder Awiri Okha Okha Okha Okha Okhala ndi Msoko Waukulu Wamkati
Malo ogwirira ntchito awa amagwiritsidwa ntchito makamaka popangira kuwotcherera kwa msoko wamkati wa girder yayikulu ya girder iwiri. Pambuyo poti chakudya chamanja chikhale pakati pa mbali zopingasa ndi zoyimirira, chogwirira ntchitocho chimazunguliridwa ±90° ndi makina otembenuza a L-arm hydraulic, ndipo lobotiyo imayang'ana malo owotcherera. Ubwino wa msoko wowotcherera wakonzedwa bwino kwambiri, ndipo kugwira ntchito bwino kwa kuwotcherera kwa zigawo za crane kwakonzedwa bwino, makamaka kuwotcherera kwa msoko wowotcherera wamkati kwawonetsa zabwino zazikulu. Ndi muyeso winanso wa Henan Mine kusamalira antchito ndikukweza khalidwe ndi magwiridwe antchito.
