729· Stripping ratio is the ratio of the volume of waste rock stripped off to the volume of ore exploited during the process of surface mining. It indicates the volume of waste rock required to be stripped for mining per cubic ore. Stripping ratio (see Fig. 1) is an important technical-economic indicator in open-pit mining, which reflects the economic benefits of open …

The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 2:1 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.
