Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate since some ore is left behind in pillars . Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom.

What are the main methods of mining? American Geosciences Institute

There are four main mining methods: underground, open surface pit , placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...

Early Mining Methods HouseFuel

Room and pillar mining was a great idea, and methods similar to this are still used in different mining practices today. The downside to this however was that valuable coal had to be left behind. Longwall mining was a method where workers would mine at the coal face and as the mining face moved further along the seam, timber supports would be put in place prevent cave-ins.
