| Abstract: | In order to rapidly open the gently inclined thick seam with outburst in potential in 21 seam of Xin'an coalfield,the paper studied the rapid opening seam technology of the cross-cut of the mine with the cross borehole and sidewall cut-off borehole gas drainage measures and with the pilot roadway.The results showed that the seam opening technology could reduce the construction period of the seam opening at the cross-cut in the outburst thick seam. |
