Abstract: Aiming at the problems of difficult support and poor supporting effect of mining roadway in deeply inclined coal
seams, based on the analysis of anchor bolt support theory and the anchor bolt support reliability, this paper analyzed the law of
strata pressure behavior of mining roadways in deeply inclined coal seams and the feasibility of bolt support in the roadway of the
deeply inclined coal seam. Finally, according to the coal mine geological conditions and coal seam characteristics, the support
parameters of roadway roof, two sides and floor were determined.
