Underground Mining Method Selection Using WPM

2017-5-17  When mining is carried below the surface of the earth is called the underground mining. Underground mining depends on many physical, mechanical, economical and technical parameters. These parameters may be qualitative and quantitative. Hence, underground mining method selection falls under multi-attribute decision making work.
