| Abstract: | Using numerical simulation FLAC,analysis is made on the distribution characteristics of stress and plastic zone in the working faces and coal pillars during highwall mining with auger machine. The mechanical effect and damage mechanism are studied of coal pillars when pillars width or vertical septum between the working faces is reduced,which provides the basis for the design of coal pillars and working faces during highwall mining with auger machine. |
| Keywords: | rock mechanics highwall mining with auger machine mechanical effect coal pillar stability |
