Chapter 2: The Environmental Effects of Strip Mining - ,
This section describes the five main types of surface coal mining techniques: area mining, open pit mining, contour mining, auger mining, and mountaintop removal Underground mining is also considered in this section Terrain, economics, and custom generally dictate which technique an operator .
The next step is to conduct a feasibility study to evaluate the financial viability, the technical and financial risks, , These are oil and gas extraction, coal mining, metal ore mining, nonmetallic mineral mining and quarrying, and mining support activiti
Mountaintop removal is any method of surface coal mining that destroys a mountaintop or ridgeline, whether or not the mined area will be returned to what is legally described as the “approximate original contour”
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
