surface mining underground steep
Moving towards deep underground mineral resources
2023.1.1 Surface subsidence can also result from underground mining, which can be significant depending on mine size, orebody shape, mining excavation method and mine depth. In general, mining-induced surface subsidence becomes less problematic with

Surface mining - Wikipedia
There are five main types of surface mining as detailed below. Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as overburden removal. It is most commonly used to mine coal and lignite (brown coal). Strip mining is only practical when the ore body to be excavated is relati
