What Are Mining Techniques For Basalt 2

Commonly used mining techniques to extract coal

 · Surface mining: The mining technique is used when the coal seam is present near the earth's surface. The techniques followed in surface mining include openpit mining, strip mining and mountaintop removal. While openpit mining involves extraction of coal from an open pit in the ground, strip mining includes stripping surface layers to reach coal deposits. Contour strip mining, area strip ......
