This study provides a systematic solution and process for monitoring the disturbance and reclamation of surface coal mining in a large range with little known about the mines' location. It can effectively identify the mining disturbance and reclamation process which can also be extended to other areas, providing a quantitative assessment of ...

While the successful reclamation of coal postmining land sites in Indonesia has been evaluated, no costbenefit analysis has been carried out on the reclamation of mined land, and the impact of the reclamation work has not been determined. The results of this case study indicate that reclamation work is not an emissionfree process, but that the benefits delivered from this work are considerable.

The findings could lead Congress or the Department of the Interior to take steps to make sure unreclaimed mines get reclaimed, she said. The lawmakers have asked GAO to quantify the number, location and size of coal mines that have neither produced coal or made reclamation progress, and whether bonding or other financial assurances are adequate to address the problem.

The reclamation process for all surface mining—including coal, bentonite, and trona—is very similar. When mining begins, the top soil—the top layer of fertile soil in which plants grow—is removed and saved for later use. The overburden—the soil that covers the mineral—is also removed and saved. Once mining operations are finished ...
