Abstract

Surface coal mining may disrupts the carrying capacity of water, hence the sustainability of water resources during mining operations and post-mining depends on environmental services of mining void. This research was designed to study the environmental costs and benefits of mining void water (general term of pit lake in Indonesia) in PT. Adaro Indonesia on site Tanjung, Kabupaten Tabalong, South Borneo, Indonesia to understand the factors influencing mining sustainability through utilization of mining void or mining pit, and to develop a model for water resources sustainability in coal mining. The main factor influencing mining sustainability is the void water quality. pH is the key factor which determines how mining void water may be used. Water utilization is based on the demands of the surrounding community, andincludes drinking water, fish farming, and land farming. Calculations on the environmental services provided by mining void water for tourism, drinking water supply, and fish farming in PT. Adaro Indonesia shows an Extended NPV of Rp 7.124.884.062.739.430 (± USD 593, 740, 338, 561.62) and B/C ratio of 8, 25.
