Mae Moh mine is the largest open-pit lignite mine in Southeast Asia. It is located some 600 km from Bangkok, in Lampang province in the north of Thailand. The new mining equipment, with capacities of up to 18 000 t/h, will be used to remove, convey and dump overburden. Two barracuda compact bucket wheel excavators with belt wagons and hopper cars will be supplied by thyssenkrupp, as well as two spreaders with tripper cars. Within the scope of the order thyssenkrupp will take care of engineering, procurement, construction and commissioning of the continuous mining system.
Thanks to its continuous operation the new mining system will help reduce both operating costs and environmental emissions at the Mae Moh mine. This is made possible by the use of two barracuda bucket wheel excavators that are able to work in hard material layers. Combined mining and loading of material by a single machine eliminates the need for blasting and separate loading operations.
