富家矿复杂难采矿体回采技术研究与实践

摘要

Complicated and hard-to-mine orebodies are essential in improving the utilization rate of geological re-sources.Take the transformation project of Fujia Mine from open-pit to underground mining for engineering back-ground,the paper in detail analyzed technical indexes of wing and wedge pillars in the 130 m stage.Based on produc-tion practices in Fujia Mine ,the recovery technology of hard-to-mine orebodies is introduced .The recovery of such ore-bodies achieves satisfactory economic results and benefits the recovery of middle depth minor and residual hard -to-mine orebodies in recovery design and construction for provision of new ideas and methods .%复杂难采矿体回采对于提高地质资源利用率具有非常重要的作用。以富家矿露天转地下开采为工程背景，详细分析了130 m中段两翼矿柱和楔形矿柱“复杂难采矿体”的开采技术条件；结合富家矿的生产实际，介绍了复杂难采矿体的回采技术，难采矿体回采取得了很好的经济效果，并为后续中深部边、残等难采矿体的回采设计、施工提供了新的思路和方法。
