| Abstract: | This paper takes the section coal pillar left in the residual coal pillar working face in 412 plate area of Meiyukou mine as an example,In order to analyze the stability of the coal pillar,a mechanical model is established to calculate the width of the coal pillar.FLAC3D numerical simulation and similar material simulation experiments are used to simulate the plastic zone and the failure of the coal pillar under two different width coal pillars,and the stability of the calculated width of the coal pillar is verified. |
