#0183;#32;The common stripmining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of overburden (if needed), stripping, removal of the coal or other mineral commodity, and reclamation.
For example, since the passage of the 1977 Surface Mining Control and Reclamation Act (SMCRA) in the, direct fees have been collected by government agencies from existing coal mining companies. Various states and Native American tribes have used over US billion of those funds to reclaim almost 240,000 acres of hazardous highpriority coalrelated problems.

Surface mining methods: Strip Mining involves stripping the surface away from the mineral thats being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucketwheel excavators.
Draglines and continuous excavators move or displace the overburden from the active pit to the previous pit that has had the coal removed. The primary planning mechanism used in strip mining is the range diagram, which is a crosssectional plan of the shape of the pit in various stages of mining.
When a resource occurs in shallow horizontal deposits near the surface, the most effective mining method may be strip mining. During strip mining, layers of surface soil and rock are removed from large areas to expose the resource. After heavy machinery removes the soil and rock, the resource is extracted. Then, the soil and rock are replaced.
A strip mining technique wherein an active mining area is continuously moved across a mining ground. Overburden is removed from a leading end of the active mining area and conveyed by a conveyor system located on a highwall of the mining area to a following end of that mining area. The conveyed overburden is dumped adjacent the active mining area following end to form a spoil bank which is
Area strip mining with concurrent reclamation. The operator places spoil from the box cut on the side away from the direction in which mining will progress. In large mines, huge stripping shovels or draglines remove the overburden. Typical open pit mining method with thick coal seam.
#0183;#32;The character of the disturbance depends upon the disposition of the mined strata, and upon the methods used to mine them ().Continued improvement of coalmining methods is associated with the exploitation of deeper coal seams (below 1000 m in deep mining operations and a few hundred metres in surface or stripmine operations).
2 #0183;#32;Land reclamation, the process of improving lands to make them suitable for a more intensive use. Reclamation efforts may be concerned with the improvement of rainfalldeficient areas by irrigation, the removal of detrimental constituents from salty or alkali lands, the diking and draining of tidal marshes, the smoothing and revegetation of stripmine spoil areas, and similar activities.
Under SMCRA, prior to receiving a mining permit, operators must present a detailed and comprehensive plan for reclaiming the land after mining has been completed. The reclamation plan must include, among other criteria, the premining condition and use of the land to be mined; the proposed use of the land after reclamation; an estimated time table for the reclamation; and the steps that will be taken to comply
