The Bagger 288, a bucket-wheel excavator, digs into the beet fields behind the farm of Norbert Winzen to expand Germany's Garzweiler coal mine, one of Europe's largest open-pit mines.

The intelligent construction of open-pit coal mines is still in its initial stage. The automation of equipment, design, and management information does not meet the requirements of intelligent mining. Therefore, the intelligent transformation, upgrading, and development of open-pit coal mines is an urgent and difficult task.

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of the IPCC system can reduce mining flexibility and introduce additional mining sequence requirements. This paper investigates the long …

Dragline excavators in mining are used to remove overburden – anything that's in the way of getting to the real product. For example, removing soil and rock from the surface above the coal seam. This overburden is repurposed, in some cases set aside to refill the open pit when the resources are exhausted.

Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd
