Mining is the removal of valuable raw materials or other geological materials from the earth, from an ore body, vein or (coal) seam. The term also includes the removal of soil. Materials healthier by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Any fabric that cannot be grown through agricultural processes, or created unnaturally in a laboratory or factory, is usually mined. Mining in a wider sense include taking away of any non-renewable resource.Mining of stone and metal has been done since pre-historic times. Modern mining processes involve prospect for ore bodies, analysis of the profit possible of a proposed mine, removal of the desired resources and finally retrieval of the land to get ready it for other uses once the mine is closed.
The nature of mining process creates a potential unenthusiastic impact on the environment both during the mining operation and for years after the mine is closed. This impact has led to most of the world's nations adopt system to moderate the negative effects of mining operation. Safety has long been a concern as well, though modern practices have superior safety in mines considerably.
