Study on the Magnitude of the Roadway-Protection Pillar in the Isolated Face

Abstract:

In the actual production process, Zhengli Coal Mine has a problem to make sure that the width of chain pillars. This paper from the view of field application with theoretical calculation and numerical simulation method to calculate and verify the stability and security of the chain pillars, It achieved good effect and finally determined the width of chain pillars.
