邢台矿提高资源回收率综合技术研究

Study on the composite technology for improve resource recovery rate in Xingtai mining area

介绍了邢台矿试验和开发的冲积层露头区保护煤柱综放开采、综放分步旋转开采、沿空无护巷煤柱开采、近距离跨巷开采和铁路煤柱开采等综合技术,以及该矿加大资源管理力度,使矿区资源回收率达到90%以上的具体作法。

This article introduces the comprehensive techniques such as composite caving method in protective pillar in alluvium outcrop zone,composite caving step rotational mining,pillar mining without protective roadway along goaf,short distance working across over roadway and coal pillar mining under railway,that were experienced and developed in Xingtai mining area,and practical measures for strengthening resource management to guarantee above 90% of resource recovery rate.
