Mengingat besarnya "Dampak yang disebabkan oleh Aktifitas Tambang" diperlukan upaya-upaya pengelolaan yang terencana dan terukur. Pengelolaan lingkungan di sektor Pertambangan biasanya menganut prinsip Best Management Practice. US EPA ( 1995) merekomendasikan beberapa upaya yang dapat digunakan sebagai upaya pengendalian dampak kegiatan tambang terhadap sumberdaya air, vegetasi dan hewan liar.

Beberapa upaya pengendalian tersebut adalah :

Menggunakan struktur penahan sedimen untuk meminimalkan jumlah sedimen yang keluar dari lokasi penambangan.
Mengembangkan rencana sistim pengedalian tumpahan untuk meminimalkan masuknya bahan B3 ke badan air.
Hindari kegiatan konstruksi selama dalam tahap kritis.
Mengurangi kemungkinan terjadinya keracunan akibat sianida terhadap burung dan hewan liar dengan menetralisasi sianida di kolam pengendapan tailing atau dengan memasang pagar dan jaring untuk Mencegah hewan liar masuk kedalam kolam pengendapan tailing.
Minimalisasi penggunaan pagar atau pembatas lainnya yang menghalangi jalur migrasi hewan liar. Jika penggunaan pagar tidak dapat dihindari gunakan terowongan, pintu-pintu, dan jembatan penyeberangan bagi hewan liar.
Batasi dampak yang disebabkan oleh frakmentasi habitat minimalisasi jumlah jalan akses dan tutup serta rehabilitasi jalan-jalan yang tidak digunakan lagi.
Larangan berburu hewan liar di kawasan tambang. Sedangkan ringkasan upaya pengelolaan yang direkomendasikan untuk setiap tahapan-tahapan kegiatan dapat dilihat pada tabel 3.

Prodjosumarto (1992) telah mengidentifikasikan beberapa upaya pengelolaan yang lazim digunakan bagi kegiatan Pertambangan di Indonesia. Upaya-upaya pengelolaan tersebut diuraikan sebagai berikut :

Tahap Persiapan Penambangan (Mining Development) Pembukaan atau pembersihan lahan (Land Clearing) sebaiknya dilaksanakan secara bertahap, artinya hanya bagian lahan yang akan langsung atau segera ditambang. Setelah penebasan atau pembabatan selesai, maka tanah pucuk (Top Soil) yang berhumus dan biasanya subur jangan dibuang bersama-sama dengan tanah penutup yang biasanya tidak subur, melainkan harus diselamatkan dengan cara menimbun ditempat yang sama, kemudian ditanami dengan tumbuh-tumbuhan penutup yang sesuai (rumput-rumputan dan semak-semak), sehingga pada saatnya nanti masih dapat dimanfaatkan untuk keperluan reklamasi lahan bekas tambang.

Pada saat mengupas tanah penutup (Striping of Overburden) jalan-jalan angkut yang dilalui alat-alat angkut akan berdebu, oleh sebab itu perlu disiram air secara berkala. Bila keadaan lapangan memungkinkan, hasil pengupasan tanah penutup jangan diibuang kearah lembah-lembah yang curam, karena hal ini akan memperbesar erodibilitas lahan yang berarti akan menambah jumlah tanah yang akan terbawa air sebagai lumpur dan menurunkan kemantapan lereng (Slope Stability).

Bila tumpukan tanah tersebut berada ditempat penimbunan yang relatif datar, maka tumpukan itu harus diusahakan berbentuk jenjang- jenjang (Benches) dengan kemiringan keseluruhan (Overall Bench Slope) yang landai. Disamping itu cara pengupasan tanah penutup sebaiknya memakai metoda nisbah pengupasan yang konstan (Constant Stripping Ratio Method) atau metoda nisbah pengupasan yang semakin besar (Increasing Stripping Ratio Method) sehingga luas lahan yang terkupas tidak sekaligus besar.
