| Abstract: | To take the Taiping coalmine in Jining City, Shandong Province as an example, the authors introduced measures of simulating test and numerical analysis, carried out in-depth analysis and research of pillar stress and strain states, strength mechanics and long-term stability of leaved pillars during thin bedrock partial extraction. Revealed interrelation between pillar stability, stress distribution and partial extraction dimension, recovery ratio, overlying strata features. Carried out partial extraction pillar stability assessment, provided theoretical basis for engineering practices. |
