柔性网铺顶工艺在大采高末采贯通中的应用

Flexible Net Roofing Technology of Mining Height Late through Mining

利用高强度柔性网,加强对工作面末采期间回撤通道破碎顶板与煤壁的稳定性控制,从而实现综采工作面安全快速回撤,是保证矿井安全高效生产的重要环节。文章主要介绍了万利一矿31303大采高工作面末采贯通期间,使用高强聚酯纤维柔性网对末采顶板进行维护的工艺流程,并且阐述了使用过程中所遇到的问题以及对应的解决方法,可以为类似开采条件的矿井提供借鉴。

To use of high - strength flexible net to strengthen the mining face during the late retracement channel broken roof and coal wall stability control,in order to achieve safe and fast retracement mechanized mining face is an important part of the mine to ensure safe and efficient production. The article describes a mine during the late Manley 31303 Large Working through mining,the use of high - strength polyester fiber flexible mesh roof for maintenance of the late mining process, and describes the problems encountered during use and the corresponding solutions the method can provide reference for similar mining conditions of the mine.
