锡铁山铅锌矿充填孔钻探施工技术探索

Technical Exploration of Filling Hole Drilling Construction in Xitieshan Lead-zinc Mine

摘要:

充填采矿法采矿是减少矿山矿产资源浪费和环保的一项开采新技术,具有良好的社会效益、经济效益。锡铁山铅锌矿充填孔因地层复杂，工期紧，施工难度很大。在施工中对钻进工艺进行优化组合，同时配套钻具级配、钻进参数优化选择，达到了施工的目的。另外在钻孔孔斜控制和测量方法上采用具有针对性的方法组合，对孔斜控制提供了有利的技术保障。

Abstract:

Backfill mining is a new technology to reduce the waste of mineral resources and environmental protection; it has good social and economic benefits. The complex formations of Xitieshan lead-zinc mine and tight schedule made the construction difficult. By the optimized combination of drilling technologies, drilling tool gradation matching and optimization of drilling parameters in the construction process, the construction is completed. In addition, the targeted combination is adopted in hole deflection control and measurement, which provides the favorable technical support for hole deflection control.
