Analisa Air Bawah Tanah pada Lokasi Tambang Batubara Tanah Laut Kalimantan Selatan

Abstract

 The impact of coal mining will produce a reservoir due to cutting and excavation from the mined area. If it is left without any effort to improve the environment due to mining it will have an impact on the surrounding environment. Research conducted by the author to determine the effect that occurs with a reservoir due to coal mining in the surrounding area. Based on measurements using the geoelectric method, it can be seen the condition of the soil layer in the reservoir and surrounding areas so that it can be estimated the movement of underground water in the aquifer layer. By using a piezometer around the reservoir it can be seen the change in the level of the underground water level at a certain time and the water level in the reservoir is measured in elevation so that it can be predicted the flow direction that occurs. From the results of the study obtained the underground water level has a greater value than the water level in the reservoir, especially in the rainy season. This activity is the initial stage of the study to determine the effect of the reservoir on underground water conservation. For the next stage measurements are needed throughout the year by installing logers so that data can be recorded automatically digitally and doing model simulations using Modflow software to predict the effect of reservoirs on underground water conservation in the long.
