Abstract
Mining is a rapid process of topographical change, the former sand mining area is a complex problem between the legal aspects of land ownership, environment, geohydrology, technology and socio-economic. The former sand mining area is quite extensive in the area along the Cisadane River which includes Tangerang Regency and Bogor Regency, for proper management of the area, a study needs to be carried out in the form of identifying the condition of the former sand mining quarry. This study aims to identify ex-mine pit and the complexity of problems in the management plan of the former sand mining area. This study was carried out only by evaluating published map maps and field observations from aspects of geology, geohydrology and environment. In the study area there were 112 holes in the sand excavation hole, 57 in the Bogor district and 55 holes in the Tangerang Regency with a range of 0.9 to 9.4 ha. The former sand hole is always filled with water so it becomes a lake or it is never dry because this mining exploits sand in the form of aquifer sand. From the existing holes there is no one who reclaims according to good and correct mining rules. Utilization of former excavation holes is relatively not optimal, only 1 is used as a source of rural clean water. Mapping of former sand mining areas is absolutely necessary for sustainable planning and management of environmentally sound management.
