Masih bisa mas koko. Ada banyak cara. Bisa di remediasi, di bersihkan longsorannya, trus slope design-nya diubah (di gali ulang) menurut itung2annya geotek. Atau pakai rekayasa engineering, bisa dipasang concrete atau teknik perkuatan lereng lainnya. Yg pasti sih dari segi cylce time tambang akan berubah, pengaruh ke sisi operasional, finansial, produksi, dll.
