Abstract
This paper studied the importance and challenges of deformation control of surrounding rock in ultra-advance section of coal mining face,discussed the common deformation control technology of surrounding rock in ultra-advance section by analyzing the deformation characteristics of ultra-advance section of coal mining face,and put forward the improvement strategy.The experimental results show that using this strategy can effectively control the deformation of the surrounding rock in the ultra-advance section,improve the safety and production efficiency of the coal mining face.
