Kafukufuku Woyesera Pa Kugwiritsa Ntchito Ufa wa Granite Mu Konkire

M'zaka zaposachedwa, makampani opanga miyala yomangira ku China apita patsogolo mofulumira ndipo akhala dziko lalikulu kwambiri padziko lonse lapansi lopanga, kugwiritsa ntchito, ndi kutumiza kunja miyala. Kugwiritsa ntchito mapanelo okongoletsera pachaka mdzikolo kumaposa 250 miliyoni m3. Minnan Golden Triangle ndi dera lomwe lili ndi makampani opanga miyala yomangira kwambiri mdzikolo. M'zaka khumi zapitazi, chifukwa cha kupita patsogolo kwa makampani omanga, komanso kukongola kwa nyumbayo komanso kukongola kwake, kufunika kwa miyala m'nyumbamo kuli kwakukulu kwambiri, zomwe zabweretsa nthawi yabwino kwambiri kumakampani opanga miyala. Kufunika kwakukulu kwa miyala kwathandizira kwambiri pachuma cha m'deralo, komanso kwabweretsa mavuto azachilengedwe omwe ndi ovuta kuthana nawo. Mwachitsanzo, Nan'an, kampani yopanga miyala yomangira bwino, imapanga matani oposa 1 miliyoni a zinyalala za ufa wa miyala chaka chilichonse. Malinga ndi ziwerengero, pakadali pano, pafupifupi matani 700,000 a zinyalala za ufa wa miyala amatha kukonzedwa bwino m'derali chaka chilichonse, ndipo matani oposa 300,000 a ufa wa miyala sakugwiritsidwabe ntchito bwino. Popeza kuti anthu akumanga malo osungira zinthu komanso osamalira chilengedwe, n’kofunika kwambiri kufunafuna njira zogwiritsira ntchito bwino ufa wa granite kuti tipewe kuipitsa chilengedwe, komanso kuti tikwaniritse cholinga chokonza zinyalala, kuchepetsa zinyalala, kusunga mphamvu komanso kuchepetsa kugwiritsa ntchito mphamvu.
