Everything You Need To Know About Open Pit Mining – Positive Points
Open pit mining (also known as strip mining) is the process of extracting ore, minerals and/or fossil fuels that occurs on the surface of a particular mining site. When considering all the mining operations in the world, at least 40 percent of mining takes place at the surface reports Greenpeace International.

7 Different Types of Mining Processes – NewsMag Online
Hydraulic mining uses water to break the ore away and carry it to the surface. In underground mining, one of the most difficult problems to solve is how to get the coal back up to the surface. With hydraulic coal mining, water is pushed at high pressure against the ore’s surface, breaking away the chunks bit by bit.
