Reasons of Great Mining Height Coal Side Fall and Study of Supports Preventing Technology

Abstract:

In order to control the side fall of coal face in great mining height fully mechanized face,this paper proposes a way of controling side fall by ensuring supports setting force,accelerating development,supporting timely of the fully mechnized face and making good use of supports sprag units on the basis of side fall influence study and side fall principle analysis. This paper not only analyses factors influencing stability and explains kinds of sprag units phenomenon of coal face in working face but also conducts quantitative analysis on the influence and provides theoretical basis for measures in order to prevent coal side fall in working face.Meantime,those measures this paper provides are all effectively in controlling coal side fall in great mining height fully mechanized.
