Open Pit Mining - an overview | ScienceDirect Topics

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

What Are the Disadvantages of Opencast Mining?

Opencast mining, also known as surface mining or strip mining, has disadvantages that include disturbance of the environment and local ecosystems, exposure of radioactive elements and contamination of freshwater sources. The use of heavy machinery and blasting techniques also create environmental pollution.

Effects Of Mining on the Environment and Human Health

Strip mining accounts for about 40 percent of the world's coal mines but in some countries, such as Australia, open cast mines make up 80 percent of mines. Even though it's highly destructive, industry often prefers strip mining as it requires less labour and yields more coal than underground mining.

Coal - Department for Energy and Mining

In 1943, open-cut mining began in the Telford Basin but was transferred in 1956 to smaller deposits at North Field, where coal was easier to extract. The best coal in these deposits was worked out by 1976, after which operations returned to the larger but deeper deposit in the Telford Basin.

For example, except under special circumstances, only underground mining is allowed in NSW, whereas in South Australia both underground and open cut mining are permissible. In Queensland open cut mining is the norm and bulldozers and 20 to 40 tonne excavators are widely used. Exploration is undertaken by surface prospecting and drilling.
