Dip-Angle-Effect-Based Deformation and Failure Law of Steeply Dipping Stope Roofs with Large Mining Heights
Abstract:Dip-Angle-effect-BAseD DeformAtion AnD fAilure lAw of steeply Dipping stope roofs with lArge mining heightsThe deformation and failure law of stope roofs is more complicated than horizontal coal seams affected by the angle of the coal seam during the mining process of steeply dipping coal seams. This study focused on and analysed the working face of a 2130 coal mine with steep dipping and large mining height. Through the use of numerical calculation, theoretical analysis, physical similar material simulation e… Show more
