分段空场嗣后充填采矿法在厂坝李家沟采区的应用

Application of Sublevel Open Stoping with Subsequent Filling Mining Method in Lijiagou Mining Area of Changba

以厂坝铅锌矿李家沟采区为实例,详细介绍了分段空场嗣后充填采矿法安全高效环保开采工艺应用,包括采切工程布置、回采工艺、应用效果及在生产过程中需注意的问题。现场开采实践表明,该开采方法具有生产能力大、效率高、成本低、作业安全性高、地压活动得到有效控制等特点,实现了矿体开采的安全、高效、经济的技术目标。

Taking Lijiagou mining area of Changba lead-zinc mine as an example, the application of the sublevel open stoping with subsequent backfill mining technology is introduced in detail, including the layout of mining and cutting engineering, mining technology, application effect and problems needing attention in the production process. The field mining practice shows that the mining method has the characteristics of large production capacity, high efficiency, low cost, high safety and effective control of ground pressure activities, so as to achieve the technical goals of safe, efficient and economic mining of ore bodies.
