deep level underground gold mining

DEEP LEVEL GOLD MINING - Rhodes High School

2020-4-17  Underground gold mining- gold is extracted from the rock known as ore. These mines can be very deep nearly 4 km underground . Extracting gold underground required expensive machinery and only the rich could afford it . Conditions underground are damp and dark some can be very hot and noisy and the tunnels maybe covered with hot,

Exploring the use of deep level gold mines in South Africa ...

This paper explores the viability of deep level gold mines in the Far West Rand (FWR) gold field, South Africa (SA), for underground pumped hydroelectric energy storage (UPHES). Ultra-deep, non-flooded shafts, extensive underground storage space, and abundance of water from an overlying karst aquifer make gold mines in the FWR exceptionally ...

Opportunities and Challenges in Deep Mining: A Brief ...

2017-8-1  The average depth of metal mines in South Africa has reached 2000 m, and the Western Deep Level gold mine has reached 4800 m . Deep rock mass is characterized by high in situ stress, high temperature, and high water pressure. Compared with shallow resource extraction, deep mining may be associated with disasters such as rockbursts, large-scale ...

How Gold Is Mined Gold Mining Process World Gold

2021-11-1  The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well ...

Some Challenges of Deep Mining - ScienceDirect

2017-8-1  For classical underground mining, that is, where miners extract ore via shafts, tunnels, and various mining methods, the depth to which the mine can be operated economically depends on the market value of the ore extracted. Thus, for a deposit with a gold content of 10 gt −1 and a market price for gold of $40 g −1, the ore is worth $400 t ...
