Abstract

Underground mining location Ciurug L.450 south, there is a lot of water entering or stagnant in the mine opening hole. At Ciurug L.450 south there are 10 mine sumps. The pumping system flows from one mine sump to the next mine sump to the main mine sump. The pump is used 24 units and is used interchangeably because electricity is limited and one pump works 15 hours / day. The purpose of this study is to reduce the number of pumps that do not work optimally and the use of electric power. Groundwater discharge measurements were carried out manually in three locations namely Ramp Down A, Ramp Down B, and Ramp Down C using trenches. Based on observations and data analysis, groundwater discharge XC 445 2,899 (m3 / m), XC 438 B 8,940 (m3 / m), and XC 438 A 1,440 (m3 / m). The actual electricity consumption of 1561,7 Kw was reduced after being designed to be 1061.5 Kw, and a design 19 pumps units was used.Keywords: Flow System, Pump, Water Discharge

Abstract

Pertambangan emas rakyat tanpa ijin (PETI) di wilayah Hampalit, Kabupaten Katingan menyisakan bentang alam dan lubang bekas tambang yang tergenang air. Penggunaan merkuri (Hg) dalam proses pengolahan emas (amalgamasi) dapat mencemari lingkungan dan sangat berbahaya jika dalam kondisi terlarut. Penelitian ini dimaksudkan untuk mengetahui kondisi air permukaan terhadap kandungan Hg terlarut pasca tambang emas rakyat. Penelitian dilakukan dengan metode purposive sampling method, pada 4 titik sampling. Sampel 1 Hg = 0,000541 mg/l; sampel 2 Hg = 0,00211 mg/l; sampel 3 = Hg = 0,00017 mg/l; sampel 4 Hg 0,00105 mg/l. Nilai Ambang batas Hg pada air limbah tambang emas adalah maksimum 0,005 mg/l dan untuk air minum adalah 0,001 mg/l. Indeks Pencemaran Air = 1,776387. Sehingga berdasarkan Keputusan Menteri Lingkungan Hidup No. 115 tahun 2003, status mutu air lokasi penelitian adalah tercemar ringan. Upaya pengelolaan air limbah pasca tambang emas rakyat adalah dengan pembuatan kolam pengendapan, penggunaan zeolit sebagai penyerap Hg dalam air, fitoremidiasi dan pemantauan baku mutu air.
