| Abstract: | Using FLAC 3D to build the corresponding analytical model,the maximum stress concentration factor,the characteristics of supporting the pressure in the plastic zone were studied in a different angle of the wall in front of the coal seam and mined-out area;combined with the field measurement of the specific production of mine,and laws of pressure behavior in the steeply dipping seam mining were obtained,which could provide guidance to the support measures. |
