摘要
随着矿山尾矿量的增加及土地资源的稀缺,安全环保地解决矿山的尾矿堆存问题是矿山企业必须研究的重要课题。新城金矿在旧库淤泥质软基上,采用碎石桩与反压法相结合的方法进行软基加固,然后采用池填法技术筑坝扩容。新增库容为93.89×104m3,延长尾矿库服务年限2.86年。该项目取得了预期的工程效果和经济效益。
With the increasing of tailings and the scarcity of land resources,how to solve the tailings storage with safe and environmental-friendly method is an important subject for mines.In old tailings pond,the soft soil foundation has been reinforced in Xincheng Gold Mine by using the method combined gravel pile and anti-pressure.Then the technology of pond filling method is used to build dam and expand capacity of tailings pond.The capacity of tailings pond in Xincheng Gold Mine has been increased to 93.89×104 m3,and the service life is extended 2.86 years.This project has obtained the expected engineering result and economic benefit.
