大采高综采工作面过陷落柱收尾技术研究

摘要

The closing work is a supporting complicated , labor-intensive important part,which directly effect the rate of retracement of work-ing face and closure time also prevent potential accident.Closing while top coal caving with great mining height cause collapse column,in order to keep the integrity and stability of the weak cementation of roof,put forward the method:full-anchor+graticule+I-steel shed to strong and dis-posable combined supporting,which ensure the working face retreat the equipment rapidly and safely.%综采工作面收尾是一项支护工艺复杂、劳动强度大的重要环节,直接影响工作面回撤速度、封闭时间和有效预防事故隐患. 遇大采高陷落柱收尾时, 为加强陷落柱弱胶结状顶板完整性和稳定性,提出实施了"全锚+经纬网+工字钢棚"强力一次联合支护方式,保证了工作面快速、安全的回撤设备.
