| Abstract: | Based on pressure observation on the mine, the circular change rule of working resistance of hydraulic support on light-support caving face of residual mining area, pressure distribution along the trend of working face, the laws of top-coal and roof movement in high-stress area in one coal mine have been analyzed.Results show that the light-support for the working face has a reasonable supporting parameters and a good adaptability.It is concluded it's safe and reliable to use light-support caving technology to recover boundary coal pillar in high-stress mining area. |

| Keywords: | light caving support high stress isolated working face of residual mining |
