In addition to being safe and efficient, precision surface mining methods are helping miners create better sustainability practices. The vibrations caused by blasting can damage nearby infrastructure, including roads, utility lines, pipelines and buildings. To avoid this, mines are forced to abandon areas within close proximity to these obstacles.

mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic substance, coal, is often discussed as a mineral as well.)
