Abstract
Reclamation in the former mining area is a series of ongoing activities with planned post-mining activities, so that the reclamation activity plan is adjusted to the post-mining activity plan. However, a lot of ex-mining land at this time, especially abandoned tin mine in Bangka Belitung Province is not well covered so it does not meet the applicable post-mining rules. Planning for reclamation of ex-mining land that has been abandoned or that has been re-mined by the community is a challenge to represent a concrete manifestation of sustainable management in the Indonesian mining sector, which refers to Government Regulation No. 78 of 2010 and the Minister of Energy and Mineral Resources Decree No. 1827 2018. Preliminary investigation of the condition of the land to be reclaimed is done by using a "drone", so that data collection can be done quickly and can present the original condition. "Drone" equipment is equipped with the concept of photogrammetry so that the results can be used for topographic map making. Some factors that need to be considered in the reclamation of alluvial tin mining are geological hazards, hydrological, hydrogeological, re-mining and monitoring. With good data from these aspects, good engineering can be carried out to realize the reclamation of the land of the former alluvial tin mine that is sustainable.
