Surface mining refers to a category of mining where soil and rock overlying the mineral deposit are removed. There are several types of surface mining, and strip mining counts as one of them. In strip mining, a thin layer of material known as an overburden is removed so that access is made to the minerals buried underneath. Usually, strip mining is employed in mining tar sand and coal. First, the trees, shrubs and other structures in the area to be mined are removed — a task accomplished with heavy duty bulldozers.

Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you. Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam profitable bed of coal is located, extracting this black gold can require a smorgasbord of options.
What Are the Pros and Cons of Strip Mining?
Learn something new every day More Info Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth. Surface vegetation, soil, and rocks are removed in strips, often in conjunction with controlled explosions, to make removal more efficient.
Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient. Unfortunately, this economy comes with a strict environmental cost because the surface environment is destroyed and polluted during the mining process.
