The Kadapa district of Andhra Pradesh state is one of the richest districts abounds in minerals with large reserves with high grade Barytes and uranium, industries and lust tropical forest. The district is famous for its Barytes mines in the country which is located in the Mangampeta mandal. In Mangampeta mining operations have been going on since 1976 by opencast mine method and waste overburden is removed and dumped in the nearby areas up to a distance of 6 km on either side of the road. The dumps are invariably associated with pockets of soil/carbonaceous tuff overburden or waste rock incorporated in to the tailings. Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. Modern day mines, particularly in jurisdictions with well-developed mining regulations are operated by responsible mining companies, often incorporate the rehabilitation and proper closure of tailings areas in the mining costs and activities. For example, the Province of Quebec, Canada, requires not only submission of closure plan before the start of mining activity, but also the deposit of a financial guarantee equal to 100% of the estimated rehabilitation costs. The quantities and measurements of the mine and the overburden with mine dumps parameters are obtained from maps or field surveys. An attempt is made here to estimate the same using open source digital data and digital means of estimation using ASTER surface. The volume estimated through digital means and data sheet of the mine provided are in tandem to a satisfactory extent.
