Once coal removal is complete, final regrading takes place and the area is revegetated. The operation is required to reclaim the mine to "AOC" or "approximate original contours" unless this requirement has been waived by the agency that has granted the Surface Mining Control and Reclamation Act of 1977 (SMCRA) permit for the operation.

Mine operators for some time now have been increasingly turning to an alternative to conventional rip-and-stack or drill-and-blast coal mining: the use of surface miners. Diverse studies and tests ...
Aug 28, 2018· The 4200 SM surface miner was integrated into an ongoing operation for the selective mining of coal and interburden. Previously defined targets were checked regularly to determine if they were being met. The project score card (Figure 1) illustrates the advantages of using a surface miner in this mine.
Mining Operation: Types, Impacts and Remedial Measures! Mining is the process of taking mineral and other substances from the earth. These substances include metal compounds, non-minerals such as coal, sand, oil and natural gas and many other useful things.
In general, most contemporary surface mining operations rely on mobile drill rigs, hydraulic shovels, front-end loaders, scrapers and haul trucks to extract ore and initiate ore processing. The larger the mine operation, the larger the capacity of equipment required to maintain the mine plan.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.

results. Generally, a near-surface coal deposit is mined using surface mining methods, and a deep deposit by underground methods. Mining of coal begins once the mineable coal reserve is determined; depending on the chosen method, coal reserve is an input to the mine operations, and the output incudes coal which is stockpiled at the mine then ...
