Ukuze kuthuthukiswe ukuphepha kwesakhiwo, iHong Kong icacise imininingwane ephelele yenqubo yokusetshenziswa kweizinqwaba zomhlabathi ezihlanganisiwe: imikhiqizo enobukhulu be-zinc engu-≥ 85 μ m futhi ehambisana nezindinganiso ze-GB/T 13912 kumele ikhethwe. Ukuhlolwa kwe-geology kumele kwenziwe ngaphambi kokwakhiwa, futhi abasebenzi abaqinisekisiwe kumele basebenzise imishini ekhethekile yokufaka ejwayelekile, belawula ngokuqinile ukuma kanye nokujula kokungcwaba. Ngemva kokufakwa, kuyadingeka ukuhlolwa kokucindezelwa nokucindezela kanye nokuqinisekiswa kokuqina komlilo. Imikhiqizo engafaneleki ayivunyelwe ngokuphelele ukungena endaweni ukuze kugwenywe izingozi zokuphepha ezivela emthonjeni.

I-Hong Kong isungule indlela yokulawula yesikhathi esideizinqwaba zomhlabathi ezihlanganisiwe, kudinga ukuhlolwa njalo kwezingxenye eziveziwe, ukwanda kwemvamisa ngemva kwesimo sezulu esibi kakhulu, kanye nokulungiswa ngesikhathi esifanele komonakalo wokugqwala kanye nowendlalelo lwezinki. Ngesikhathi esifanayo, sungula incwadi yokusebenzisa, ucacise umkhawulo ophezulu wempilo yenkonzo yeminyaka engama-30, bese ugunyaza ukuthi kushintshwe izinqwaba zomhlabathi eziphelelwe yisikhathi noma ezonakele. Uhulumeni uzophinde aqinise ukuhlolwa okukhethekile kanye nokuqeqeshwa kwabachwepheshe ukuze bandise izinzuzo zabo ekuvimbeleni ukugqwala, ukuvimbela umlilo, kanye nokuzinza.
