摘要
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。
Complicated and hard-to-mine orebodies are essential in improving the utilization rate of geological resources. 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 production practices in Fujia Mine, the recovery technology of hard-to-mine orebodies is introduced. The recovery of such orebodies achieves satisfactory economic results and benefits the recovery of middle depth minor and residual hard-tomine orebodies in recovery design and construction for provision of new ideas and methods.
