| Abstract: | For the characteristics of rock crosscut coal uncovering outburst in gently inclined outburst coal seam，and combined with numerous studies and practice of Ⅱ1 coal uncovering in Jiaozuo mining area，determining the coal uncovering technology which through short pilot tunnels shock-blasting with cross borehole pressure relief gas drainage in gently inclined outburst coal seam. Achieved safe exposing coal in 2415 and 2417 yard in Fengying Coal Mine，and provided protection for mining deployment reasonably. |
| Keywords: | uncovering coal short pilot tunnels gently inclined shock-blasting |
