| Abstract: | According to the action of cantilever rock seam on the overly- ing strata of coal body, the paper analyses the distribution rule of abutment pressure and the theoretical basis of narrow pillar drift and exploies the sup- port type of drifts in inclined and steep inclined coal seam under the condi- tion of narrow pillar drift. |
