摘要
为探索安全、快速、高效的综放工作面末采回撤技术,华电煤业不连沟煤矿针对性的引用柔性聚酯纤维网,在厚松散层特厚煤层综放工作面末采收尾时使用,通过现场使用并与原铺设金属网铺顶工艺进行对比、分析、总结,逐渐掌握了适用于本矿地质特点的柔性聚酯纤维网末采铺顶工艺技术,为类似开采条件下,综放工作面的安全、高效末采回撤提供了新途径,具有推广应用价值。
To explore safe, fast and efficient at the end of the fullymechanized caving mining retracement technology, huadian Buliangou coal mine specific references to the flexible polyester fibres, especially at the end of the thick coal seam fully - mechanized caving mining in thick loose bed ending when use, through the field use and compared with the original metal net shop roof laid technology, analysis, summary, gradually mastered the applicable to the geological characteristics of mine shop at the end of the web mining technology, flexible resin for similar mining conditions, at the end of the safe and efficient mining caving mining working face retracement provides a new way, popularization and application value.
