大采高综采工作面预打地锚加固底板快速搬家技术研究

Research on Fast Moving Technology of Pre-driving Ground Anchor to Reinforce Floor in Fully Mechanized Mining Face with Large Mining Height

综采工作面利用预打地锚加固底板技术代替回撤通道底板硬化方法,在进行回撤通道底板加固的同时,保证了液压支架的顺利回撤,缩短了搬家工期,实现了大采高综采工作面的快速搬家。

In the fully mechanized mining face,the technology of reinforcing the floor with pre driving anchor instead of the hardening method of the withdrawal channel floor can ensure the smooth withdrawal of the hydraulic support,shorten the moving period and realize the rapid moving of the large mining height fully mechanized working face.
