Large-scale mining of deep pit is a problem that has never been encountered before, and it is also one of the development trends of the mining industry in the future.
Sishanling iron ore mine, as the first large-scale deep mining pit that is about to be put into production in China, encountered technical difficulties such as design of a sizeable stope, deep pit filling, monitoring and control of rock mass stability.
In order to provide guarantee for the safe and efficient production of the mine, exploit the key technology of large-scale deep pit mining, and to promote the development of domestic deep mine large-scale mining industry and technology, Longxin Mining organised a large-scale Key Issues and Technical Seminar Held in Benxi.
