Pros and Cons of Strip Mining | APECSEC
The Pros of Strip Mining. 1. High Recovery Rate. Other forms of mining do not guarantee the same rate of return as strip mining does. Materials are recovered at a rate of up to 90 percent during strip mining, which is a much higher recovery rate than most forms of mining can promise. Tunnel mining, for instance, only offers users a …

What Is Surface Mining? | Types of Surface Mining
These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

Types, Effects and Solutions to Strip Mining
Strip mining is a form of surface mining for mineral deposits, which allows the overburden (soil, rock, etc.) to be removed from an ore body by mechanical means and then placed in nearby dumps or valleys. The main products are coal and oil shale. Strip mining is the process of extracting ore or minerals from the earth by first removing overburden.
Mining is bad for health: a voyage of discovery
Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining.

7.3.2: Contour Mining | GEOG 000
Mountaintop removal is another submethod of contour mining where a flat lying coal seam occurs near a mountain top and outcrops on opposite sides of a hill. When the overburden is sufficiently thin (less than 165 feet) across the hill, the deposit can be mined from outcrop to outcrop. In this method the hill is completely removed and the spoil ...
