UNDERGROUND HARD ROCK MINING SUBSIDENCE
http://www.nswmin.com.au
When there are low concentrations of minerals in the ore body,
large amounts of ore need to be extracted and processed for the
mine to be economical. This can be done through open cut methods
or underground methods, with the appropriate method depending
on local circumstances, such as the depth of the ore body. 5
Some of the underground methods used to extract large volumes
of ore include block caving and panel caving. Each of these methods
involves tunneling under the ore body, fracturing the overlying ore
body and allowing it to cave down through gravity to underground
draw points where it can be extracted for processing. 10
When the ore body caves down, the overlying rock subsides
forming a subsidence zone at the surface. At the surface, the subsi-
dence zone will typically take the shape of a cone of depression with
steep slopes at the edges. There may also be some surface cracking
around the edges of the subsidence zone. The area and depth of 15
the subsidence zone will depend on the local conditions, such as the
amount of ore extracted and the nature of the local geology.
Access to the subsidence zone is restricted and any built or natural
features in this zone will generally be lost. Impacts caused by sub-
sidence are fully assessed during the project approval process with 20
appropriate measures implemented to minimize or offset any impacts.
The aim of conducting inquiries on subsidence zones is to promote opportunities for:
