Abstract: Taking the pressed coal in Qi village of Yuwu Coal Company as experimental purpose. The methods of theoretical calculation, surface movement, numerical simulation and deformation prediction are adopted to analyze the safety range of mining and remaining width, different coal pillar mining plan, coal pillar stability as well as surface deformation prediction caused by mining under Qi village，it suggest that the mining under Qi village is feasible, which improves the mining rate of coal resource，prolongs the service life and realizes the safety mining of the coal resource under the case of un-removing.
