In such cases, punch highwall mining is more effective than the conventional highwall mining. This paper describes conventional highwall mining and punch highwall mining systems and discusses the stability of the highwall due to punch highwall mining at opencut coal mines.
Determining the financial stability of surety companies has been challenging in certain instances. ... Why GAO Did This Study. Coal accounts for 17 percent of domestic energy production. SMCRA requires coal mine operators to reclaim lands that were disturbed during mining and to submit a financial assurance in an amount sufficient to ensure ...
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 .
Slope stability of overburden dumps plays as integral part of opencast mine project throughout the operation process. Waste dumps always have steep angled slopes as the waste has been tipped over from the top of the dump in a continuous and progressive manner. For new landfill it is often desirable to design steep slopes as it can accommodate the maximum amount of waste possible.
DroneBased Aerial Intelligence Platform for Coal Mining With regular flights using the Kespry solution, material removed from a shaft, incline, adit, or opencast mine is easily tracked in the Kespry Cloud.
The prefeasibility study defines an opencut strip mining operation utilising conventional truck and shovel equipment for overburden removal, Continuous Surface Miner for coal mining and waste backfilling to maximise inpit dumping thereby ensuring minimal environmental disturbance.

Coal mining, under current US regulations, has significantly reduced the abundance and variety of fish, invertebrates, salamanders, and other aquatic life in streams, according to a new study from the University of Tennessee, Knoxville.
The study has highlighted the coalproducing regions and geological issues related to high roof fall rates in underground coal mines. These results can be used to direct research, support technology development and mine layout alternatives.
In mining: Pit geometry .a pit have a certain slope determined by the strength of the rock mass and other factors. The stability of these walls, and even of individual benches and groups of benches, is very important—particularly as the pit gets deeper.
