Stability Mechanism and Process Optimization Practice of High Bench Dumping in an Open Pit Mine
With the development of open-pit mine dumping technology,high-efficiency and low-cost high-bench dumping technology is widely adopted by open-pit mines at home and abroad.The increase in the height of the dumping section can significantly improve the efficiency of mining dumping and reduce the construction of dumping roads and other engineering quantities.High bench dumping refers to the dumping parameters that are greater than normal conditions.In terms of cost,it has significant advantages,so high bench dumping technology has become a new development trend in open-pit mine dumping technology.However,high step soil dumping is not necessarily better as it has limitations.The determination of reasonable parameters for an open-pit mine's dumping site should be tailored to local conditions,and different mines should combine their respective dumping processes for parameter selection.The designed bench height of the Tongman mining site's Nanjia waste dump is 40m,but based on the analysis of the on-site conditions in Nanjia,it is believed that there is room for improvement by appropriately increasing the height of its waste dump section.The application of high bench dumping technology has solved the production difficulties of enterprises and reduced their dumping costs.The relevant experience is worthy of reference and application in similar mines.
