Overall the start-up phase for a mine from exploration and property development to first mine production may take in excess of 10 years Mining Surface mining involves the removal (stripping) of surface vegetation dirt and if necessary layers of bedrock to reach buried ore deposits below Common techniques for surface mining include
Type of surface mining that uses explosives massive shovels and even larger machinery called draglines to remove rock/earth to expose seams of coal underneath a mountain Reclamation employs stronger more extreme techniques to clean up severe pollution or create a newly functioning ecosystem on a seriously degraded or barren site General Mining Act of 1872 A United States federal law
The decline in the production of surface mined coal in the UK is not reflected elsewhere in the world where in general production from surface mines has increased in recent years Despite the fact that most coal reserves are only exploitable through underground mining globally some 40% of coal is now surface mined The USA produces 50% of its coal from such mines (see

Somebody from Some company Says "It doesn't matter if your mining job takes you underground or keeps you on the surface What matters is how much material you produce and move how quickly you do it and how much it costs you each shift If you're not moving enough material working as efficiently as you need to and saving (and making) money in the process then it's time for better
Surface Mining Surface mining allows extraction of ores that are close to Earth's surface Overlying rock is blasted and the rock that contains the valuable minerals is placed in a truck and taken to a refinery As pictured in Figure below surface mining includes open-pit mining and mountaintop removal Other methods of surface mining
Mining Surveillance System (MSS) was launched on January 24 2017 It aims to curb illegal mining activity through automatic remote sensing detection technology Road Ahead There is significant scope for new mining capacities in iron ore bauxite and coal and considerable opportunities for future discoveries of sub- surface deposits
Surface Coal Mining The primary methods of surface coal mining used in Pennsylvania are Strip Mining Layers of soil and rock overburden are removed the coal exposed coal seam is excavated The area is then backfilled regraded and replanted during the reclamation process Highwall Mining An outcrop of coal is removed by traditional excavators or by using auger mining (drilling directly

Surface mining for coal has taken place in the Central Appalachian region of the United States for well over a century with a notable increase since the 1970s Researchers have quantified the ecosystem and health impacts stemming from mining relying in part on a geospatial dataset defining surface mining's extent at a decadal interval This dataset however does not deliver the temporal
In the operating ropes of large surface mining equipment not all characteristics have equal importance There are two characteristics – resistance to metal loss and deformation and fatigue resistance – that are usually the main considerations Most applications require a balance of these two characteristics The strength of the ropes can also be important of course when considering a
