Room and Pillar Mining. In this method, mining is carried out in an ore deposit, leaving behind some of the ore in the form of columns to support the roof and prevent it from collapsing. Thus, it results in the formation of spaces called rooms, where the ore is excavated with pillars of ore distributed throughout.

Chapter 4 Mining waste

The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 21 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often deposited in piles or heaps close to the mine to minimize transports.
