16.2: Mining, Processing, and Generating Electricity
Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in which overburden is sequentially …
Uranium: How is it Mined?
Uranium resources can be extracted from the ground in three ways: open pit, underground, and in-situ leach (ISL). Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the …

Enormous machines dig up the ground in stair-stepped layers (called "benches") until the copper is extracted using drilling equipment and explosives. Once each layer is fully extracted, the next one is made until there isn't enough ore to mine profitably. Underground mining is more expensive and complex than open-pit mining.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
