Digging deeper: Mining methods explained Anglo American

Underground mining has a lower ground footprint than open pit mining. What is underground 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

Underground Mining for Meeting Environmental Concerns A

Jan 01, 2015 Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an open-pit of comparable capacity. The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.

Mining footprint: a spatial indicator of environmental

Jan 31, 2019 Since mining footprint can demonstrate the extent of environmental impact zone around a mine site, therefore, a spatial indicator can be designed on the basis size of a mining footprint. Seventeen air, sixteen soil, five surface water and six groundwater samples from a manganese mining region in Bhandara district, Maharashtra, were analysed.

Block caving: A new mining method arises Geoengineer

Jul 25, 2018 Block cave mining is the only underground method that can offer comparable open pit production rates and operating costs. For new developments, block cave mining offers the further advantage of a smaller surface footprint with significantly less waste disposal requirements.

State of Play: Ecosystem Low footprint mining innovation

In-line mining uses technology to shift processing underground “to the face” to reduce the movement of waste material and the operational footprint above ground. In-mine mining uses refrigerants to build a wall around an orebody and avoid contamination when subsequently leaching the ore.

Mining: Making the Most of Radioactive Caches How

Nov 15, 2011 Experts say in-situ recovery leaves a smaller footprint on the environment, as well as a smaller reclamation tab for mining companies [sources: Deery; Hunter]. Some operations use heap leaching,a process by which companies extract ore, break it into smaller pieces above ground and leach the pile with chemicals to separate the uranium.

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 ore below. Ore grades are normally less than 0.5%.
