Design of Mining Boundary for Yinjng Limestone

Mining boundary directly concerns economic benefits, so its design is very crucial. According to the given news about Yunjing mountain limestone such as geographic location,surrounding environment,topography-geomorphology, ore body occurrences , resources reserves and so on, this paper makes a design of mining boundary for Yinjng limestone following the rule that average stripping ratio is less than economic stripping ratio. This design will provide some guidance for the construction and production of the limestone.
