Hunter Valley Coal Chain

Coal generally goes through the following stages between mine and port: The producer makes arrangements to sell coal to a buyer on certain terms. The coal is mined (most of the coal mines in the Hunter Valley are open cut mines, also known as open pit mines), processed, blended and stored either at a railway siding located at the mine or at a coal loading facility (used by several mines).

Open Cut and Underground Mining | iMINCO

Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

What is open-cut mining?

Open-cut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit. To uncover the minerals the land is first cleared of vegetation as when a new building like a house, school, factory or shop is constructed but in the case of open-cut mining, the top soil is removed and stockpiled for later use in the rehabilitation process.
