Abstract
Kondisi Hidrogeologi suatu daerah rencana penambangan perlu diketahui secara baik untuk menunjang kelancaran pelaksanaan terhadap kegiatan selanjutnya.oleh karena itu, sebagai antisipasi akan dilakukanya perencanaan tambang terbuka untuk endapan Batubara di Daerah Sungai Merdeka, Kec. Samboja, Kabupaten Kutai Kartanegara, Provinsi Kalimantan Timur, PT. Singlurus Pratama melakukan penyelidikan Hidrogeologi. Kajian Hidrogeologi yang dilakukan meliputi kondisi Hidrologi Daerah Sungai Merdeka.debit Air limpasan, sifat hujan, sistem dan karakteristik akuifer, potensi Air tanah. Data curah hujan di dapatkan dari stasiun Badan Meteorologi dan Geofisika Bandara Temindung Samarinda yaitu data 10 tahun terahir (2001-2010) dengan curah hujan tahunan berkisar (1.676,3– 2.757,5) dan hari hujan (187 – 261) daerah penelitian termasuk curah hujan cukup tinggi. Nilai debit air limpasan pada Blok Sungai Merdeka ialah 70-117 m3/detik. Berdasarkan hasil uji akuifer di lapangan dengan metode slug test dan konstan heard diketahui nilai permeabilitas (K) dari akuifer di Blok Sungai Merdeka berkisar antara (4,875 x 10-13- 4,975 . 10-6) meter/detik. Kualitas air permukaan tanah berdasarkan nilai pH dan DHL dari hasil analisis kimia conto air, diketahui bahwa air permukaan maupun airtanah di daerah penelitian berpotensi bersifat asam. Abstract Hydrogeology condition of a mining plan area should be well known to support the smooth implementation of activities selanjutnya.oleh therefore, as an anticipation of the execution of plans for open pit coal deposits in the River Region Merdeka district. Samboja, Kutai Kartanegara, East Kalimantan, PT. Singlurus Pratama Hydrogeology investigation. Hydrogeology studies performed included the Regional Hydrological conditions Merdeka.debit River Water runoff, rain properties, and characteristics of the aquifer system,ground water potential. Rainfall data get from the station of the Meteorology and Geophysics Temindung Samarinda Airport is the last 10 years of data (2001-2010) with annual rainfall ranging from (1676.3 to 2757.5) and rainy days (187-261) area of investigation, including bulk rainfall is high. Value of the runoff water discharge on the River Block is 70-117 m3/second Merdeka. Parameters of the aquifer was drilled to test Slug test drilling conducted on 6 drill holes, Based on the results of aquifer tests in the field with the slug test method known and heard the constant value of permeability (K) of the aquifer in the block between River Merdeka (4.875 x 10-13 - 4.975. 10-6) m / sec. Quality of ground water based on pH value and conductivity of the results of chemical analysis of water samples, it is known that the surface water and groundwater in the area of investigation could potentially acidic.
