Study on law of Mine Pressure Behaviors at Fully Mechanized Face in Thin Coal Seam with Large Inclined Angle

Lei Han

Abstract

Taking 7246 coal face in Taoyuan Coal Mine as an example,by measuring and analysis on the working face support resistance,the law of mine pressure behaviors is revealed,which is at a fully mechanized face in a thin coal seam with large inclined angle,and the operation condition of hydraulic supports and the adaptability for the roof and floor in 72 coal seam are analyzed,for future production practice significance.
