| Abstract: | Based on the roof classification of individual hydraulic prop longwall face in Nanliang mine,the paper analyzed the support condition of the mining face and proposed the measures of forced caving method which can prevent the disaster of large area caving.The method is important to prevent roof disaster and achieve the mining face advancing continuity in individual hydraulic prop working face in shallow seam. |
| Keywords: | shallow seam large area caving roof classification disaster prevention |
